M e t h o d o l o g y The purpose of this study report is to provide recommendations and guidance to American Lime Technology on which ASTM material tests may best fit the projected use and formulation of Tradical Hemcrete.

Tradical Hemcrete is a unique product that replaces several other building materials in a wall assembly: gypsum board, vapor retarder, siding, insulation, sound baffles, etc. As such, research was undertaken as part of this study to ascertain the building materials Hemcrete replaces and how those materials are traditionally tested. ModCell Hemp was not evaluated as part of this report.

As part of this study the project team:• Reviewed all previous completed testing and product data• Utilized the IBC (International Building Code) to ascertain how code official may view Hemcrete• Met with the client to discuss the future goals for product use• Established the materials Hemcrete replaces in a building wall assembly• Identified similar “traditional” and “innovation” building materials that have previously undertaken similar testing • Identified appropriate ASTM tests• Identified appropriate test agencies• Identified the impact of regional issues (i.e. humidity, seismic, wind, etc...)

Fi n d i n g s M a t r i xThe information provided in the Matrix depicts the types of construction and ASTM test. The intent of this matrix is to provide recommendations on what test likely suite specific types of construction. The use of this matrix should assist in targeting ASTM tests that most suite your goals for Tradical Hemcrete in the United States.

Tests denoted as “required” for code compliance on the matrix are essential to receive code approval for product use. Tests denoted in the matrix as “recommended” are not specifically required by code but are strongly encouraged to collect hard product data and inform code officials. Tests denoted as “not critical” are more driven towards gathering product data for marketing purposes and general information but not essential to any code official requirements. Tests denoted as ”not applicable” do not apply to the type of construction. Please note that “recommended” tests also speak to issues addressing individual states which may have regionally specific issues such as hurricanes. The information provided in no way speaks to standards in other countries.

Ty p e s o f C o n s t r u c t i o nPages 8 and 9 provide information on types of construction including definitions and typical building types. This information is critical in determining the types of buildings targeted for the Hemcrete market. Use this information to supplement the decision making process provided in the Matrix for determining which ASTM test are the most valuable to your end goal market needs at this time.

A S T M Te s t s D e f i n e dThe information provided in the section “ASTM Tests Defined” is meant to provide American Lime Technologies with a synopsis of information pertinent to determining which tests may be the most appropriate and how they are implemented. In their complete form, each ASTM section fully defines and instructs testing agencies as to how testing should actually be carried out. This in depth information is lengthy and not necessary for your purposes. Gaps in numeric sequences are not errors but are omissions of data more pertinent to testing agencies.

NOTE: Each test is considered proprietary. Once testing is complete and Hemcrete passes, compliance with the ASTM standard is only achieved through exact duplication of how the material was formulated/installed at the time of testing. Therefore, each sample/mock-up supplied to the labs should be an exact replica of how the product will be installed/specified in the field.

ASTM: E 84 Surface Burning Characteristics of Building Materials

0.0 Preface This test is the standard to establish the relative behavior of a finish material when exposed to open flame.

1.0 Scope1.1 This fire-test-response standard for the comparative surface burning behavior of building materials is

applicable to exposed surfaces such as walls and ceilings. This test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side.

1.2 The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.

1.3 The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.

1.4 Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in a low flame spread indices (measurement) that do not relate directly to indices by testing materials that remain in place.

4.0 Significance and use4.1 This test method is intended to provide only comparative measurements of surface flame spread and smoke

density measurements with that of select grade red oak and reinforced cement board surfaces under the specific fire exposure conditions described herein.

4.2 This test method exposes a nominal 24 ft (7.32-m) long by 20 in. (508 mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 5 1/2 min.

4.3 This test method does not provide the following:4.3.1 Measurement of heat transmission through the tested surface.4.3.2 The effect of aggravated flame spread behavior of an assembly resulting from the proximity of combustible

walls and ceilings.4.3.3 Classifying or defining a material as noncombustible, by means of a flame spread index by itself.

6.0 Test Specimens6.2 The specimen shall be provided in one of two ways: (1) a continuous, unbroken length; (2) sections that will

be joined or butted end-to-end.6.3 The size of the test specimen shall be: Width: between 20 and 24 in. (508 and 610mm) Length: 24 ft. + 12 in. - 6 in. Thickness: maximum 4 in. (101 mm)



11.0 Report11.1.4 Observations of the burning characteristics of the specimen during test exposure, such as delamination,

sagging, shrinkage, fallout, etc.11.1.5 Graphical plots of flame spread and smoke development data.

ASTM: E 119 Fire Tests of Building Construction and Materials0.0 Preface This test is the standard to establish the fire resistance of a building assembly (a system of components or materials). 1.0 Scope1.1 The test methods described in this fire-test-response standard are applicable to assemblies of masonry

units and to composite assemblies of structural materials for buildings, including bearing and other walls and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs. They are also applicable to other assemblies and structural units that constitute permanent integral parts of a finished building.

1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.

1.4 These test methods prescribe a standard fire exposure for comparing the test results of building construction assemblies. The results of these tests are but one factor in assessing predicted fire performance of building construction and assemblies. Application of these test results to predict the performance of actual building construction requires the evaluation of test conditions.

4.0 Significance and use4.1 This test method is intended to evaluate the duration for which the types of assemblies notes in 1.1 contain

fire, retain their structural integrity, or exhibit both properties dependent upon the type of assembly involved during a predetermined test exposure.

4.2 The test exposes a specimen to a standard fire controlled to achieve specified temperatures throughout a specified time period. When required, the fire exposure is followed by the application of a specified standard fire hose stream. The test provides a relative measure of the fire-test-response of comparable assemblies under these fire exposure conditions. The exposure is not representative of all fire conditions because conditions vary with changes in the amount, nature and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. Variation from the test conditions or specimen construction, such as size, materials, method of assembly, also affects the fire-test response. For these reasons, evaluation of the variation is required for application to construction in the field.

4.3 This test standards provides for the following:4.3.1 For walls, partitions, and floor or roof assemblies:4.3.1.1 Measurement of the transmission of heat.4.3.1.2 Measurement of the transmission of hot gases through the assembly, sufficient to ignite cotton waste.4.3.1.3 For load bearing elements, measurement of the load carrying ability of the test specimen during the test

exposure.

9.0 Test Specimen9.1 The test specimen shall be truly representative of the construction for which classification is desired, as

to materials, workmanship, and details such as dimensions of parts, and shall be built under conditions



representative of those obtaining as practically applied in building construction and operation. The physical properties of the materials and ingredients used in the test specimen shall be determined and recorded.

9.2 The size and dimensions of the test specimen specified herein shall apply for rating constructions of dimensions within the range employed in buildings. When the conditions of use limit the construction to smaller dimensions, the dimensions of the specimen shall be reduced proportionately for a test qualifying them for such restricted use.

TEST OF BEARING WALLS AND PARTITIONS14.0 Size of Specimen14.1 The area exposed to fire shall be not less than 100 ft2 (9m2), with neither dimension less than 9 ft. (2.7 m).

The test specimen shall not be restrained on its vertical edges.

TEST OF NONBEARING WALLS AND PARTITIONS17.0 Size of Specimen17.1 The area exposed to fire shall be not less than 100 ft2 (9m2), with neither dimension less than 9 ft. (2.7 m).

Restrain the test specimen on all four edges.

ASTM: E 136 Behavior of Materials in a Vertical Tube Furnace0.0 Preface This test is the standard to establish if a material is combustible or non-combustible.

1.0 Scope1.1 This fire-test-response test method covers the determination under specified laboratory conditions of

combustion characteristics of building materials. It is not intended to apply to laminated or coated surfaces. 1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and

flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.

4.0 Significance and use4.1 While actual building fire exposure conditions are not duplicated, this test method will assist in indicating

those materials which do not act to aid combustion or add appreciable heat to an ambient fire.4.2 Materials passing the test are permitted limited flaming and other indications of combustion.

6.0 Test Specimen6.1 All test specimens shall be 38 by 38 by 51 + 2.5 mm (1.5 by 1.5 by 2.0 + 0.1 in.). The specimens shall be dried

at 60 + 3oC (140 + 5oF) for not less than 24 hour but no more than 48 hours. Specimens shall not be placed in a desiccator to cool at least 1 hour before testing.

6.2 Not less than four identical specimens shall be tested.

8.0 Report8.1 Report the material as passing the test if at least three of the four specimens tested meet the individual

specimen criteria detailed in 8.2 or 8.3. The three specimens do not need to meet the same condition.8.2 When the weight loss of the specimens is 50% or less:8.2.1 The recorded temperatures of the surface and interior thermocouples do not at any time during the test rise

more than 30oC (54oF) above the stabilized temperature measured at T2 prior to the test.8.2.2 There is no flaming from the specimen after the first 30 seconds.8.3 When the weight loss of the specimen exceeds 50%:8.3.1 The recorded temperature of the surface and interior thermocouples do not at any time during the test rise

above the stabilized temperature measured at T2 prior to the test.8.3.2 There is no flaming from the specimen at any time during the test.

ASTM: E 736 Cohesion/Adhesion of Sprayed Fire-Resistive Materials Applied to Structural Members

0.0 Preface This test establishes how well an applied fire-resistive material adheres to structural steel.

1.0 Scope1.1 This test method covers a procedure for measuring the cohesion/adhesion or bond strength (tensile)

perpendicular to the surface of sprayed fire-resistive material (SFRM) applied to rigid backing. These fire-resistive materials include sprayed fibrous and cementitious materials. The test method is applicable to both laboratory and field procedures as indicated in Section 7.

4.0 Significance and use4.1 The intent of this test method is to determine a property of SFRM that may be used to provide an indication

of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during construction and during the life of the structure, as well as upon its satisfactory performance under fire conditions.

7.0 Test Specimen Note: The specimen can either be laboratory or field tested.7.1 Laboratory Tests:7.1.1 The SFRM shall be applied at a thickness of 12 mm to 25 mm (1/2 in. to 1 in.) to the 300 by 300 mm (12 by

12 in.) galvanized steel sheet.7.1.2 Condition the specimen at room temperature (20+ 10oC (68 + 18oF)). After 72 h, samples may be forced

dried in a drying oven at 43 + 6oC (110 + 10oF), and a relative humidity not greater than 60% until successive weight readings, taken at 8 h intervals, differ by less than 1 percent.

7.1.3 Testing may be performed after it has been determined that all samples have reached constant weight as defined in 7.1.2.

7.2 Field Tests:7.2.1 The test specimen shall be the in-place SFRM as applied to any field condition surface. Where a 300 mm

(12 by 12 in.) area is not available, such as on beams and fluted deck, use the width of the beam or the width of a flute by 300 mm (12 in.) length. The area shall be at least 100 by 300 mm (4 by 12 in.). See 5.2 for exceptions.

7.2.2 Condition the specimen at atmospheric conditions or in accordance with the manufacturer’s recommendations for a period sufficient to be considered dry.

7.2.3 Mechanical ventilation may be employed on the manufacturers’ recommendation to expedite drying. 8.0 Procedure8.1 Apply adhesive sufficient to fill the metal or plastic cap, and immediately place the cap against the surface

of the SFRM.8.2 Support the cap at the surface until the adhesive has adequately cured. Wipe away any excess adhesive

around the cap before it cures, or carefully cut it away after it cures.8.3 Laboratory Tests:




8.3.1 Restrain the specimen with the SFRM facing up to prevent movement and flexing during testing. 8.3.2 Engage the scale with the hook and exert an increasing force at a minimum uniform or incremental rate of

approximately 5 kg (11 lb)/min perpendicular to the surface.8.3.3 Force shall be applied until failure occurs, a predetermined value is reached, or until the capacity of the scale

is reached. 8.4 Field Tests:8.4.1 Perform tests as described in 8.3.2-8.3.4.8.4.2 A nondestructive field test may be performed by replacing the scale with a fixed weight that must be

supported for 1 min.

10.0 Report10.1 Report the following information:10.1.1 Force, newtons (pounds force),10.1.2 Cohesion/adhesive force (bond strength), pascals (pounds per 10.1.3 Description of the type of failure.10.1.4 Approximate area of material involved in the failure, if it extends beyond the perimeter of the cap.10.1.5 Thickness of the SFRM.10.1.6 Density of the SFRM.

ASTM: E 759 Effect of Deflection on Sprayed Fire-Resistive Materials Applied to Structural Members

0.0 Preface This test establishes how well an applied fire-resistive material bonds to steel decks while under bending

stress.

1.0 Scope1.1 This test method covers a procedure for determining the effect of deflection on sprayed fire-resistive

material (SFRM) applied to steel deck. Thee materials include sprayed fibrous and cementitious materials applied directly in contact with the structural members. The test method is applicable only to laboratory procedures.

3.0 Summary of Test Method3.1 In this test method a cellular steel deck panel sprayed with fire-resistive material is subjected to bending by

a vertical center load while supported horizontally at its ends.

4.0 Significance and use4.1 The intent of this test method is to determine properties of direct-applied SFRM that may be used to provide

an indication of serviceability. Satisfactory performance of fire-resistive material applied to structural members and assemblies depends upon its ability while in place to withstand the various influences that may occur during the life of the structure, as well as upon its satisfactory performance under fire tests.

4.2 This test method measures the behavior of SFRM when subjected to deflection and evaluates such phenomena as spalling and delamination under bending stress. It is an indication of the ability of SFRM to remain in place and resist removal during anticipates service conditions.

7.0 Test Specimen7.1 Apply the SFRM to the underside of the steel deck at a minimum 19 mm (3/4 in.) thickness. Do not apply

the SFRM to the area 330 mm (13 in.) from each end of the specimen, in order to permit the steel deck to bear directly on the supports.

7.2 Condition the prepared specimen for a period of not less than one week at ambient temperatures and humidity conditions (but not less than 4.4oC (40oF)) until cured.

7.3 Condition the specimen for a period sufficient to be considered dry in accordance with the manufacturers’ recommendations.

8.0 Procedure8.1 Place the specimen on the test supports with the SFRM as the lower surface.8.2 To measure the deflection of the specimen, record the initial reading of the dial micrometer prior to the

application of the load and record the deformation of the load applied.8.3 Apply a vertical center load to the upper face of the specimen by means of a bearing block to develop a

deflection of 1/120 of the clear span, that is, 25 mm (1.0 in.).




9.0 Report9.1 Report the following information:9.1.1 Condition of the test specimen when it has deflected the required 1/120 the clear span,9.1.2 Any spalling or delamination, and9.1.3 Thickness of the SFRM in millimeters (or inches) and the density in kilograms per cubic metre (or pounds per

cubic foot).

Associated CostsNote: Costs will vary from lab to lab and do not include the cost of materials or assembly.



ASTM: E 760 Effect of Impact on Bonding of Sprayed Fire-Resistive Materials Applied to Structural Members

0.0 Preface This test establishes how well an applied fire-resistive material bonds to steel decks while under bending

stress.

1.0 Scope1.1 This test method covers a procedure for determining the effect of impact loading on the bonding of sprayed

ASTM: E 761 Compressive Strength of Sprayed Fire-Resistive Materials Applied to Structural Members

0.0 Preface This test establishes the compressive strength of an applied fire-resistive material after being applied to

structural steel.

1.0 Scope1.1 This test method covers a procedure for measuring the compressive strength of sprayed fire-resistive material

(SFRM) applied to a rigid substrate. These fire-resistive materials include sprayed fibrous and cementitious materials applied directly in contact with the structural members. The test method is applicable only to laboratory procedures.

3.0 Summary of Test Method3.1 The compressive strength of SFRM applied to steel sheet is determined by applying a crushing load normal

to the surface of the specimen. This test method measures the stress at 10% deformation or at failure, whichever is smaller.

4.0 Significance and use4.1 The intent of this test method is to determine properties of direct-applied SFRM that may be used to provide

an indication of its serviceability. Satisfactory performance of fire-resistive material applied to structural members and assemblies depends upon its ability to withstand the various influences that may occur during the life of the structure, as well as upon its satisfactory performance under fire tests.

4.2 The test method measures the compressive strength of SFRM and is a measure of the resistance to deformation under a compressive load. It is an indication of the ability of SFRM to remain in place and resist removal during anticipated service conditions.

in.). 7.3 Condition the prepared specimen for a period of not less than 72 h at room temperature (20+ 10oC (68 +

18oF)) and at a relative humidity not greater than 60%. After 72 h, the specimen may be forced dried in a dying oven at 43 + 6oC (110 + 10oF), and at a relative humidity not greater than 60% until reachig constant weight.

7.4 Testing may be performed after it has been determined that the specimen has reached constant weight.7.5 Where necessary, even the surface of the specimen at two areas 150 mm (6 in.) square at opposite ends of

the specimen with an appropriate capping material such as polyurethane, epoxy, polyester, or other similar materials. The top plane of the capping material shall not exceed the thickest point of the test area of a test specimen with an irregular surface by more than 1.3 mm (0.05 in.).

7.6 Make two compression tests at opposite ends of the test specimen. Make one density test on the specimen.

ASTM: C 1363 Thermal Performance0.0 Preface This test establishes the insulative value of a material more commonly known as “R-value”.

1.0 Scope1.1 This test method covers the laboratory measurement of heat transfer through a specimen under controlled

air temperature, air velocity, and thermal radiation conditions established in a metering chamber on one side and in a climate chamber on the other side.

1.2 This test method generally is used for large homogeneous or nonhomogeneous specimens. This test method may be used for any building structure or composite assemblies of building elements for which it is possible to build a representative specimen of a size that is appropriate for the testing apparatus.

1.3 This test method is intended for use at conditions typical of normal building applications. The usual consideration is to duplicate naturally occurring outside conditions that in temperate zones may range from approximately -48 to 85oC and normal inside residential temperatures of approximately 21oC. Building materials used to construct the specimens are generally pre-conditioned to typical laboratory conditions of 23oC and 50% relative humidity prior to assembly.

1.4 The test method permits operation under natural or forced convective conditions at the specimen surface. The direction of air flow motion may be either perpendicular or parallel to the surface.

1.8 This test method does not permit intentional mass transfer of air or moisture through the specimen during measurements of energy transfer. Air infiltration or moisture migration can significantly alter net heat transfer.

5.0 Significance and use5.1 There is a need for accurate data on heat transfer through insulations and through insulated structures.

The data are needed to judge compliance with specifications and regulations as well as design guidance, for research evaluations of the effects of changes in materials or construction, and verification of, or use in, simulation models/energy models.

5.2 For the results to be representative of a building construction, only representative full-scale sections should be tested. The specimens should be duplicate framing geometry, material composition and installation practice, and orientation of construction.

7.0 Test Specimens7.1 The test specimens shall be representative of typical product (field) applications. 7.1.1 Size - The specimen shall be sized for the apparatus. Normally, the outside dimensions of the specimen

must match the inside dimensions of the specimen frame. If smaller elements must be tested, a surround panel may be used to fill out the required size.

11.0 Calculation11.2 Average Temperature Determination: 11.2.1 When operated under steady-state conditions with temperatures held constant during a test, the results

maybe expressed as either thermal resistance, R, thermal conductance, C, overall thermal resistance Ru, or thermal transmittance, U. This allows two procedures which are to be used in determining the average



A S T M T e s t s D e f i n e d : T H E R M A L P E R F O R M A N C E

surface temperatures used in the calculations. The choice between the two procedures depends upon the uniformity of the specimen and thus upon whether sufficiently uniform surface temperature exist that they can be measured by temperature sensors and a representative average obtained.

The two procedures are :11.2.1.1 For uniform and nearly uniform specimens, the average surface temperatures may be determined from area

weighted measurements from the temperature sensors installed as directed in 6.10. The thermal resistance, R, is then calculated using the measured heat transfer and the difference in the average temperatures of the two surfaces.

11.2.2 For very nonuniform specimens, meaningful average surface temperatures will not exist. In this case the thermal resistance, R, is calculated by subtracting surface resistance fro the two surfaces from the measured overall thermal resistance, Ru. These surface resistances shall be determined from tests conducted under similar conditions, but using a uniform test specimen of approximately the same overall thermal resistance.

12.0 Report12.1.10 Net heat transfer through the specimens, steady-state average rate or the average amount per cycle or

other stated time interval for dynamic tests. Include values for metering box loss, flanking loss, and other losses included in the net energy calculation.

12.1.11 Any thermal transmission properties calculated in 11.3 (“Calculation of Thermal Properties”), and their estimated error.

ASTM: C 1262 Evaluating the Freeze-Thaw Durability of Dry-Cast Segmental Retaining Wall units and Related Concrete units

0.0 Preface This test establishes the behavior of a material to freeze/thaw cycles.

1.0 Scope1.1 This test method covers the resistance to freezing and thawing of dry-cast segmental retaining wall (SRW)

units (see Specification C 1372) and related concrete units. Units are tested in a test solution that is either water or 3% saline solution depending on the intended use of the units in actual service. (Note 1: Related concrete units include units such as hollow and solid concrete masonry units, concrete brick, and concrete roof pavers.)

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

4.0 Significance and use4.1 The procedure described in this test method is intended to determine the effects of freezing and thawing

on SRW and related units in the presence of water or saline solution. 4.2 This procedure is not intended to provide a quantitative measure to determine an expected length of

service for a specific type of concrete unit.

6.0 Sampling6.1 Selection of Test Specimens - Select while units representative of the lot from which they have been selected.

The units shall be free from visible cracks or structural defects.6.2 Number of Specimens - Select five SRW units for freeze-thaw tests.

9.0 Calculation and Report9.1 Determine and report the cumulative weight loss of each residue collection interval expressed in terms of g

(lb) and as a percent of the calcualted initial weight of the specimen determined in accrodance with 8.3.5. Where the coupon thickness is less than 1.25 in. (32mm), the percentage and cumulative weight loss shall be multiplied by a value equal to the actual thickness in inches (mm) divided by 1.25 in. (32mm). Report these values for each specimen as well as the average of the specimens tested.

(8.3.5 - At the completion of the freezing-and thawing testing, dry each specimen at 212 to 239oF (100 to 155oC) for 24+ 1h. Weigh to the nearest 1 g (0.002lb) the final oven-dried specimen and record the final weight.

ASTM: D 3273 Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber

0.0 Preface This test measures the resistance to mold growth on or within the material.

1.0 Scope1.1 This test method describes a small environmental chamber and the conditions of operation to evaluate

reproducibility in a 4 week period the relative resistance of paint films to surface mold fungi, mildew growth in a severe interior environment.

1.2 This test method can be used to evaluate the comparative resistance of interior coating to accelerated mildew growth. Performance at a certain rating does not imply and specific period of time for a fungal free coating. However, a better rated coating nearly always performs better in actual end use.

3.0 Significance and use3.1 An accelerated test for determining the resistance of interior coatings to mold growth is useful in estimating

the performance of coatings designed for use in interior environments that promote mold growth and in evaluating compounds that may inhibit such growth and the aggregate levels for their use.

5.0 Reagents and Materials5.3.2 Gypsum Board Panels, 12.7 mm (1/2 in.) thick, 75 by 100 mm (3 by 4 in.). Note: These panels (after an initial

mold growth stage) are coated with the surface coating to be tested i.e. lime wash.

8.0 Report8.1 Report the results at the end of the 4 week exposure giving the mean and range of the three panels. The

result from any panel that differs by more than 2 rating units from either of the others can be considered manifestly faulty and discarded and the mean of the remaining two panels reported. If all panels in a set differ by more than 2 units in their ratings, discard all results and repeat the test.

ASTM: E 1886 Performance of Exterior Windows, Curtain Walls, Doors, and Storm Shutters Impacted by Missles(s) and Exposed to Cyclic Pressure Differentials

TKWA Note: Given that this test is typically structured around the wind speed maps for a particular region, we suggest selecting a region that typifies hurricane level event wind loads for maximum results.

0.0 Preface This test establishes the materials resistance to flying debis. The test is primarily used to evaluate windows.

however, testing hemcrete would establish the strength and durability to aborant weather conditions. It is not out of the ordinary to test building materials in this manner.

1.0 Scope1.1 This test method determines the performance of exterior windows, curtain walls, doors, and storm

shutters impacted by missile(s) and subsequently subjected to cyclic static pressure differentials. A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment. This test method is applicable to the design of entire fenestration or shutter assemblies and their installation. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm (i.e. hurricane or tornado).

4.0 Summary of Test Method4.1 This test method consists of mounting the test specimen, impacting the test specimen with a missile(s), and

then applying cyclic static pressure differentials across the test specimen in accordance with a specified test loading program, observing and measuring the condition of the test specimen, and reporting the results.

5.0 Significance and use5.1 Structural design of exterior windows, curtains walls, doors, and storm shutters is typically based on positive

and negative design pressure(s). Design pressures based on wind speeds with a mean recurrence interval (usually 25-100 years) that relates to desired levels of structural reliability and are appropriate for the type and importance of the building. The adequacy of the structural design is substantiated by other Test Methods such as E 330 and E 1233 which discuss proof loads as added factors of safety. However, these test methods do not account for other factors such as impact from windborne debris followed by fluctuating pressures associated with a severe windstorm environment. As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused significant amount of damage to building envelopes. The actual in-service performance of fenestration assemblies and storm shutters in areas prone to severe windstorms is dependent on many factors. Windstorm damage investigations have shown that the effects of windborne debris, followed by the effects of repeated or cyclic wind loading, were a major factor in building damage.



5.1.1 Many factors affect the actual loading on building surfaces during a severe windstorm, including varying wind direction, duration of the wind event, height above ground, building shape, terrain, surrounding structures, and other factors. The resistance of fenestration or shutter assemblies to wind loading after impact depends upon the product design, installation, load magnitude, duration, and repetition.

5.1.2 Windows, doors, and curtain walls are building envelope components often subject to damage in windstorms. The damage caused by windborne debris during windstorms goes beyond failure of building envelope components such as windows, doors, and curtain walls. Breaching of the envelope exposes a building’s content to the damaging effects of continued wind and rain. A potentially more serious result is internal pressurization. When the windward wall of a building is breached, the internal pressure in the building increases, resulting in increased outward acting pressure on the other walls and roof. The intyernal pressure coefficient (see ANSI/ASCE 7), which is one of several design parameters, can increase by a factor as high as four. This can increase the net outward acting pressure by a factor as high as two.

5.2 In this test method, a test specimen is first subjected to specified missile impact(s) followed by the application of a specified number of cycles of positive and negative static pressure differential. The assembly must satisfy the pass/fail criteria established by the specifying authority, which may allow damage such as deformation, deflection, or glass breakage.

5.3 The windborne debris generated during a severe windstorm varies greatly, depending upon windspeed, height above the ground, terrain, surrounding structures, and other sources of debris. Typical debris in hurricanes consists of missiles including, but not limited to, roof gravel, roof tiles, signage, portions of damaged structures, framing lumber, roofing materials, and sheet metal... The missiles and their associated velocity ranges used in this test method are selected to reasonably represent typical debris produced by windstorms.

5.4 To determine design wind loads, average wind speeds are translated into air pressure differences. Superimposed on the average winds are gusts whose aggregation, for short periods of time (ranging from fractions of seconds to a few seconds) may move at considerably higher speeds than the averaged winds. Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and other factors are considered.

5.4.1 Wind speeds are typically selected for particular geographic locations and probabilities of occurrence from wind speed maps such as those prepared by the National Weather Service, from appropriate wind load documents such as ANSI/ANCE 7 or from building codes enforced in a particular geographic region.

5.4.2 Equivalent static pressure differences are calculated using the selected wind speeds.5.5 Cyclic pressure effects on fenestration assemblies after impact by windborne debris are significant. It is

appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm. Gust wind loads are of relatively short duration. Other test methods such as E 330 and E 1233, do not model gust loadings. They are not to be specified for the purpose of testing the adequacy of the assembly to remain unbreached in a windstorm environment following impact by windborne debris.




8.0 Test Specimen8.1 The test specimen shall consist of the entire fenestration or shutter assembly and contain all devices used to

resist wind and windborne debris. Test specimens for large fenestrations and curtain wall assemblies shall be one panel unless otherwise specified.

ASTM: E 90 Airborne Sound Transmission Loss of Building Partition and Elements (acoustic properties)

0.0 Preface This test establishes the materials sound absorbing behavior.

1.0 Scope1.1 This test method covers the laboratory measurement of airborne sound transmission loss of building

partitions such as walls of all kinds, operable partitions, floor-ceiling assemblies, doors, windows, roofs, panels, and other space-dividing elements.

5.0 Significance and use5.1 Sound transmission loss refers to the response of specimens exposed to a diffuse incident sound field, and

this is the test condition approached by this laboratory test method. The test results are therefore most directly relevant to the performance of similar specimens exposed to similar sound fields. They provide, however, a useful general measure of performance for the variety of sound fields to which a partition or element may typically be exposed.

7.0 Test Specimens7.1 Size and Mounting - Any test specimen that is to typify a wall or floor shall be large enough to include all the

essential construction elements in their nominal size, and in a proportion typical of actual use. The minimum dimension (excluding thickness) shall be 2.4 m (7’-10 1/2”), except that specimens of doors, office screens, and other smaller building elements shall be their customary size. Preformed panel structures should include at least two complete modules (panels plus edge mounting elements), although single panels can be tested. In all cases the test specimen shall be installed in a manner similar to actual construction, with a careful simulation of normal constraint and sealing conditions at the perimeter and at joints within the field of the specimen.

7.2 Aging of Specimens - Test specimens that incorporate materials for which there is a curing process (for example adhesives, plasters, concrete, mortar, damping compound) shall age for a sufficient interval before testing. Manufacturers may supply information about curing times for their products.

• Pre-consumer material is defined as material diverted from the waste stream during the manufacturing process. Excluded is reutilization of materials such as rework, regrind or scrap generated in the process and capable of being reclaimed within the same process that generated it.

• Post-consumer material is defined as waste material generated by households or by commercial, industrial, and institutional facilities in their role as end-users of the product, which can no longer be used for its intended purpose.

4. Post-Consumer recycled content is calculated using 100% of material value. 5. Pre-Consumer recycled content is calculated using 50% of the material value. • Recycled Content Value ($) = (% Post-consumer Recycled Content x Material Cost) + 0.5 x (% Pre-consumer

Recycled Content x Material Cost)6. For assembly (products that are composed of multiple materials) recycled content values, consider the percents

by weight of the post- and pre-consumer recycled content in the assembly. 7. In the case of supplementary cementitious materials (SCMs) used in concrete that are recycled from other

operations, it is allowable to calculate the recycled content value based on the mass of the cementitious materials only rather then on the entire concrete mix. (See Example 1: Sample Supplementary Cementitious materials Calculation)
