Task 3.4. Validation of horizontal solutions

Fire and mechanical characterization

I. Fire validation

Reaction to Fire Tests EN-13501-1Determines whether a material fuels a fire. The EU Reaction to fire evaluation criteria are:

the material’s ignitability, rate of heat release, rate of spread of flame, rate of smoke emission, toxic gas emission, flaming droplets/particles and/or a combination of these safety aspects.

Fire reaction requirements:

Bfl-s2 or Efl (depending on the type of building)B-s3d0 (suspended ceiling), SBI test

Contribution to fireB Very limited contribution

E Significant contribution to flashover

Smoke productions2 middle smoke production

s3 High smoke production

Flaming droplets d0 no production of flaming droplets or particles

• Ignitability test EN ISO-11925-2

• Determination of the burning behavior of floorings, using a radiant heat source EN ISO 9239-1

• Single Burning Item test EN 13823 (recommended but not required for raised floors). If this test is performed, panels could be also employed for other applications, such as suspended ceilings.

The test specimen is placed in a horizontal position below a gas-fired radiant panel inclined at 30° where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen.

The test determines the ignitability of a vertically oriented test specimen when exposed to a small flame, either at the edge or the surface of the specimen.

Resistance to fire EN-13501-2

Test criteriaTest criteria

Fire resistance tests evaluate the behaviour of the elements used in the construction sector when exposed to fire, assessing the period of time during which these elements continue to fulfill the roles for which they were designed in case of fire.

Classification Time of exposure (min)

R 15 30

RE 30

REI 30

R. The structural element should not collapse or deflect beyond the permitted levels when subjected to the applied load.

E. The integrity of the room must be maintained. No breakthrough of flames is permitted.

I. The temperature on the non-exposed side of the structural element must not rise more than 140° C above ambient as an average measurement and no more than 180° C at any one location.

Task 3.4. Validation of horizontal solutions

Fire and mechanical characterization

Mechanical validation • Static load test:

– Panels mounted in the particular pedestals as would be on site

– Stringers shall be included with another fixing elements.

– Indentor: 25mm steel cube with rounded corners

– 4 tests in different points of the panel:• At the centre of the weakest edge• At the centre of the panel• At a diagonal 70 mm from the edge of a

pedestal head

• Pedestal vertical load test: – The requirements for the test results:

• The understructure has to support 4 times the working load of the system tested

• The pedestal may not become distorted or damaged.– Indentor: 50 x 50 mm– Same fixing as intended to be use in practice.– The test has to be performed to the worst conditions of work

• Permanent deformation test on element– As a result of the test after the application of 30 min of a test load,

the residual deflection 5 min after the removal of the load shall not exceed 0,5mm.

– Test made at the weakest point of the panel.– Working load is applied by a 25 mm cube.

• Dynamic loading: – Hard body impact:

• In the test a steel indentor with a mass of 4,5 kg and with a 50mm hemispherical end shall be dropped inside a guide tube from a height of 600mm in three diferrent positions and the panel shall not collapse

• Result is given as Pass or Fail– Soft boy impact:

• The indentor is a flat bottomed canvas bag containing dried sand 2 to 4 mm diameter and with a mass of 40 kg.

• The filled bag shall be dropped on to the test panel from a height of 1 at three points of the panel and the panel shall not collapse.

– In both test the result is given as pass or fail and sufficient free space shall be available under the test panel to permit the indentors to penetrate the panel in case of failure.

• Sampling and preparation for dimensional measurement– Length of panel sides– Squareness of the panel– Straightness of sides horizontally– Thickness of the panel– Panel twist

• Peel resistance– In the test a steel indentor with a mass of 4,5 kg and with a 50mm

hemispherical end shall be dropped inside a guide tube from a height of 600mm in three diferent positions and the panel shall not collapse
