Fire: a serious problem

Fires have ahigh costin terms of loss of

human lifeand of damages to plants andstructures.

About athirdof fires originateinside buildings.

Research studies in this field state that the

most commonly identified cause of deathfrom

a fire accident is being overcome by gasor

smoke(Department for Communities and Local

Government - formerly ODPM - Fire Statistics,

United Kingdom, 2005).

Other influential sources have demonstratedthatfor the last 50 years, the average time

from ignition of a fire to flashover has gone

from 15 minutes to 3 minutes, thus seriously

complicating the escapefrom fire. And this is

due only to the increase of plastics in home and

buildings.

It has to be kept into consideration, then, that

even the most sophisticated alarm systems

or emergency systems can be uselessiftheir performances are compromisedby the

destructionof the cables because of the fire. This

is the reason why, over the last few years, the

companies havestrongly invested in designand

development of insulation material and of

cables granting the best performancesin case of

fire, while reducingfumes and acid gases emission

and grantingthe circuit integrity even in

case of fire.

Cavicelhas been present for years onto the market

with its own products and its own experience.

When talking about safety, a particular care must be paid to your interlocutor.When you then have to choose products that must safeguard systems and human lives, you haveto make sure that your choice is the right one.The cables, for instance, that quite often cannot be seen, being hidden in walls or below the oor,but run for kilometres around us, must be chosen by a company you trust.

Cavicel is present onto the market with a wide range of products, including the reresistant cables FIRECEL that are installed in over 30 countries.Buildings, skyscrapers, public buildings, chemical andpetrochemical plants, undergrounds, manifold applications thathave a common denominator: they require a safe use of cables.When selecting cables that should guarantee specicperformances in case of re, it is necessary to choose a reliablecompany, with a long experience and careful to technologyevolution.A reliable company, having a long experience that allows to gain themarket trust.

The security of our cables during a fireCavicel has started designing and manufacturing re resistant cables

in the rst 70s. Before that, it studied halogen free special compoundshaving very low fume development, when the relevant norms were notdened yet; Cavicel has then used these products in the manufacturingof its re resistant cables. In 1983 the rst patent covering an enhancedame resistant cable had been deposited and the manufacturing ofspecial products for specic requirements had been enlarged.Those have been more and more used with a wider and wider diffusion in many elds. The studyhas then included the optic bres and in 1999 Cavicel deposited a patent covering re resistantbre optic cables.To improve as much as possible the research and development activity, Cavicel has equippeditself since many years with a re test laboratory capable to carry out tests according to severalinternational standards. A bigger guarantee for our Customer.

Construction andGeneral Information

CablingFire resistant cables generally can be laid-up inconcentric construction and in pairs.Twisting is important to reduce noise in circuits andalso the lay of twist in some constructions must becarefully considered.

ScreeningScreens are often used in instrumentation cables to prevent or reducepossible interference in cables that can be caused by the followingreasons:

Cross-talk from adjacent pairs or triples; Interference induced by external source such as electricalequipments, machinery, power line.

The most popular screen is:

Aluminium/polyester tapewith a tinned copper drain wireor earth conductor

Following screens can also been used, when required:

Copper/polyester tapewith a tinned copper drainwire, for a better screen effect

Bare copper braidfor electromagneticinterference or when the cableis subject to movements

Aluminium/polyester or copper/polyester tapes normally have a total thicknessfrom 25 to 100 m, according to standards and are wrapped with an overlap>125% to assure a full coverage even in case of bending.In continuous contact with metallic side there could be an earth tinnedconductor, same cross section of the other cores, or a drain wire, normally

tinned copper, 0.5 sqmm, stranded or solid, according to cable specifications.Copper braid normally has a coverage from 80% to 95%. This type of

screen presents a lower electrical resistance, a very good protection alsoto electromagnetic noises and a higher mechanical resistance compared to

aluminium/polyester tape. It is suitable for mobile applications.

Insulation

The most widespread technologies to guarantee theelectric cables connection integrity during a re arecurrently the following:

ceramied silicone-rubber mica-glass tape and cross-linked polyolene

The taping with mica tape is the most typical solution;it allows the use of several insulation materials sincethe re resistance is guaranteed by the tape.The silicone rubber is currently the most frequentlyused solution and simplies and speeds up theinstallation, thanks to the easy peeling and to the lackof tape.

Mica-glass tape Silicone rubber

ConductorsConductors can generally be according to EN 60288:

class 1solid

class 2stranded

class 5exible

Type of conductors are chosen according to electrical characteristics,required exibility, type of connection systems or specic installationconditions, for example:

in presence of vibration or movement or reduced bending radius ispreferable class 5 exible conductor,

class 1 solid conductor is preferable for permanent installation,crimping termination,

in presence of corrosive atmosphere, high temperature or tofacilitate the soldering is preferable tinned conductor.



7/36

SheathTo optimize the behaviour in case of re, best sheathis made of LSZH (Lows Smoke Zero Halogen)materials since, thanks to that, re would not bepropagated, toxic or corrosive gases would not bedeveloped and a minimum quantity of white fumesare emitted.Other materials can obviously be used in case ofspecic installation requirements, such as:PVC, for example, where a higher resistance to oilsand chemicals is required (this material containshalogens, so it emits acid gas and smoke).

PE, when a higher resistance to water and moistureis required (this material is no anti-ame, though).


Construction and General Information

ArmouringMetallic armour are used when cables have to be installed direct buried,or if mechanical protection is required.Following points must be considered:

Required tensile load

Expected pressure on cable during service Protection against rodent Protection against accidental damage Minimum required bending radius.

SWA: single layer of galvanized steelwires, with diameters according torelevant standards, coverage min.90%. This armour assures a very goodmechanical protection and tensilestrength. An additional counterspiraltape increases solidity, if required.

GSWB: galvanized steel wire braid,diameter of wire: 0.20 - 0.25 -0.30 - 0.40 mm, with coverage of>80%. It assures a good mechanicalresistance, allowing a lower bendingradius compared to other armour. It ispreferable when there is movement orvibration.For special application is possible touse stainless steel, tinned copper orspecial alloy wires.

Standards at a glanceA higher and higher care is paid towards safetyin many places and environments in general.Fire is considered one of the most frequent cause of disasters and human lives loss.The standards have tried more and more to face this problem under various aspects.Over the last few years, particularly, both national(BS, DIN, CEI) and international(EN, IEC) standardshave gone through a remarkable evolution.The evolution, though, is so fast that it is difcult to always have an updated picture.The purpose of this sectionis therefore to provide an overview on how the standards have faced

the denition, the choice and the installation of the electric cables concerning the re risks.Reference is also made to outdated standards since they are still present in many specications.


Fire resistance

Fire resistance means that the cable or the installation where the cable is

installed is capable tocontinue to operate even in case of refor aspecic period of time (from 30 to 180 minutes).

To be more precise, it is possible to have two different denitions: Circuit Integrity (or Insulation Integrity)which indicates testsexclusively referred to cables;

System Circuit Integrity is referred to tests on cables and systems

(ladder, cable tray, clamps).

In some countries, such as Germany or Belgium, the rst characteristics

(Circuit Integrity) is often indicated by an abbreviation (FE180 in case the

test lasts 180 min) and the second one (System Circuit Integrity) by the

abbreviations E30, E60, E90 that indicate the cable resistance for 30, 60 and

90 minutes according to a specic test and with different installation systems.

Standards at a glance


Reaction to fire propagation

Cables can be a critical vehicle for the re transmissionsince they run for long tracts, even in vertical ducts that couldbehave as chimneys and therefore propagate the re even inother areas.CAVICEL useshigh self-extinguishing materials andrealizes constructive solutions that contrast the amepropagation.Normally two characteristicsare checked: non propagation

of ame on a single cable alike the wiring and the nonpropagation of ame on more cables assembled as a bunch,as generally happens for electric installations.

Behaviour to the fire of the electric cables

The behaviour of the electric cables in case of re can be evaluated according to various aspects:Fire resistance - Non propagation of re - Emission of fumes and acid gases

The rst aspect can be considered as active since the cable continues to perform its main function:

transmit power and signals even during the fire.

The other characteristics can be dened as passive, but of primary importance,by limiting the fire

propagationandby reducing fumes and gasesthat are developed by the combustion and that cause

severe damages and human lives losses. It must be considered, in fact, that most commonly identied

causes for death from a re incident are due to gas or smoke.

Emission of fumes and acid gases

CAVICELalways usesLSZH (Low Smoke Zero Halogen)sheaths for its FIRECELcables (unless when specicallyprescribed because of special working conditions). This term

indicates materials that are properly formulated to guarantee,besides the high self-estinguishing characteristic, also a low

emission of clear fumes, without halogens (corrosive gases)

and that do not developtoxic gases in case of combustion.

Other acronyms are used, some of which are registered; it

is important though that the required performance are clear.

A term which is not too clearis, for instance, the acronymLSF (Low Smoke and Fumes), that, not making any reference

to halogens, could also be referred to PVC; in this case, the

characteristics of corrosive gases absenceis missing.

Non propagation of fire Smoke Density Acid Gas Emission

Fire resistance

Fire resistance - Circuit Integrity

The rst testson re resistance cables were only providing

the presence of ame, for example for IEC 331 standards, for a

period of 180 minutes at a temperature of 750C.

Subsequentlythe test conditions have been extended, by

changing the duration, by increasing the temperature of the

ame and by adding mechanical stress and water sprays.These modications allowed to better simulatethe real re

conditions, with mechanical stresses due to the fall of materials

and with the presence of water for the putting out of the same.

The standard BS 6387has been introduced by keeping that

into consideration: it was providing three tests on three

different cable samples: one only with the ame, up to 950C

(cat. C), one with the ame and water spray (cat. W), one with

the ame and mechanical stresses (cat. Z). This test is still used

but its limit is to require three different tests on three different

cable samples.

BS EN 50200standard has solved this problem since the same

cable sample is simultaneouslystressed by the ame action,

by the mechanical shock and by water spray.

Fire resistance - Circuit integrity - Reference Standards

IEC 60331- Tests for electric cables under fire conditions - Circuit integrity. This is one of the rst tests that had been introduced to verify electric cables reresistance. Currently it is divided in more parts that describe the test modes, the conditions and the equipment to use. The test, originally carried out only inpresence of re, now also stresses the cable with mechanical shocks. In details, the standard is subdivided in several parts:IEC 60331-1 ed1.0 (2009-05)- Part 1: Test method for fire with shock at a temperature of at least 830 C for cables of rated voltage up to and including0,6/1,0 kV and with an overall diameter exceeding 20 mIEC 60331-2 ed1.0 (2009-05)- Part 2: Test method for fire with shock at a temperature of at least 830 C for cables of rated voltage up to and including0,6/1,0 kV and with an overall diameter not exceeding 20 mm IEC 60331-3 ed1.0 (2009-05)- Part 3: Test method for fire with shock at a temperature of at least 830 C for cables of rated voltage up to and including0,6/1,0 kV tested in a metal enclosureIEC 60331-11 ed1.1 Consol. with am1 (2009-07) - Part 11: Apparatus - Fire alone at a flame temperature of at least 750 C

IEC 60331-21 ed1.0 (1999-04)- Part 21: Procedures and requirements Cables of rated voltage up to and including 0,6/1,0 kVIEC 60331-23 ed1.0 (1999-04)- Part 23: Procedures and requirements - Electric data cablesIEC 60331-25 ed1.0 (1999-04)- Part 25: Procedures and requirements - Optical fibre cables

BS EN 50200:2006 - Method of test for resistance to fire of unprotected small cables for use in emergency circuits. The cable undergoes the action of the ameat 850C and mechanical shocks. The test duration is expressed in minutes and is recorded in the classication: PH 15 - PH 30 - PH 60 - PH 90 - PH 120.Annex E of the standard also foresees the water stress, as previously provided by BS 8434-1 standard.This test is equivalent to IEC 60331-2.

BS EN 50362:2003 - Method of test for resistance to fire of larger unprotected power and control cables for use in emergency circuits. This standard providesthe same tests foreseen by IEC 60331-1 standards (Temperature of the ame 830C, with mechanical stresses)

BS 6387:1994- Specification for performance requirements for cables required to maintain circuit integrity under fire conditions.This can be dened as thehistorical standard for re resistance cables since in many countries it is still the most widespread one. It has been the rst to include also mechanical stress andwater action in the re resistance test of electric cables. The cables can be tested in different conditions, but most commonly required are:Cat C- test with ame at 950C for 180 minutes.Cat W- test with ame for 15 minutes and ame and water for further 15 minutes at 650C.Cat Z - test with ame and mechanical shocks for 15 minutes at 950C.Reference is also made to constructive standards, such as BS 7629 one.

BS 8434-2:2003+A2:2009- Methods of test for assessment of the fire integrity of electric cables. Test for unprotected small cables for use in emergencycircuits. BS EN 50200 with a 930 flame and with water spray.This standard is foreseen by BS 5839-1:2002 standards and is an extension of the testconditions according to BS EN 50200 standards. The cable is stressed by the ame at 930C with mechanical shocks for 60 minutes and further 60 minuteswith the addition of water spray. Since it has not been included in the BS EN 50200 standard yet, it is still in force.

BS 8491:2008 - Method for assessment of fire integrity of large diameter power cables for use as components for smoke and heat control systems and certainother active fire safety systems.This standard is related to cables included in BS 7346-6, and certain other active re safety systems. It is applicable to cablesof rated voltage not exceeding 600/1 000 V and of overall diameter greater than 20 mm. The test method in BS 8491:2008 includes subjecting the cable undertest to radiation via direct impingement corresponding to a constant temperature attack of 842 C, to direct mechanical impacts corresponding to a force ofapproximately 10 N, and to direct application of a water jet simulating a water re ghting jet. The test method given in this standard includes three different testdurations to allow testing of cables intended for different applications.

BS 8434-1:2003 (SUPERSEDED)- Methods of test for assessment of the fire integrity of electric cables. Test for unprotected small cables for use inemergency circuits. BS EN 50200 with addition of water spray.This standard is no longer in force since it has been replaced by Annex E of the S EN 50200

standard. Reference to it is made in BS 5839-1:2002 standard, in order to add a test with water. The cable is tested at 830C for 15 minutes in presence of

ame and mechanical shocks and for 15 minutes with ame, mechanical shocks and water spray.

NF C 32-070- Tests for classification of conductors and cables with respect to their fire behaviour.This test differs from the others since the cable is not directly

in contact with the ame, but it is positioned in a steel conduit inside a circular oven. The oven reaches a temperature of 920C and this causes the cable

combustion. Mechanical shocks are applied to the conduit containing the cable; furthermore, the cable is subjected to tensile strength.

Fire resistance - System Circuit Integrity

In this case it is required a re resistance verication onthe installed cables, as for instance according to DIN 4102standards, part 12, where the cables are tested in realinstallation conditions and the resistance is veried at 30, 60and 90 minutes (the cables are in fact classied E30, E60,E90).Another standard included in this category is NBN 731.020.

Constructive standards

BS 7629-1:2008- Electric cables. Specificationfor 300/500 V fire resistant screened cables havinglow emission of smoke and corrosive gases whenaffected by fire. Multicore and multipair cables.This standard includes the currently most commoncables onto the market of the re resistant cables.Those cables are used in re alarm and emergencylighting applications. They have a rated voltage of300/500 V.Generally, the cables are particularly exible and easyto be installed.These standards require that the cables get throughthe re resistance tests prescribed by BS 6387standards.

BS 7846:2009- Electric cables. Thermosettinginsulated, armoured, fire-resistant cables of ratedvoltage 600/1000 V, having low emission ofsmoke and corrosive gases when affected by fire.Specification.

This standard refers to the armoured cables withrated voltage 600/1000 V.The circuit integrity performance under re conditionsis assessed on the basis of various tests which eitherseparately measure resistance to re, resistance tore with water, and resistance to re with mechanicalshock, or in combination measure resistance to rewith mechanical shock and water.

BS EN 60702-1:2002- Mineral insulated cables andtheir terminations with a rated voltage not exceeding750 V. Cables.These standards apply to mineral insulated cables.Those cables have an insulation completely differentfrom those seen so far: they are extremely resistant

but rigid. Their installation is not handy and aparticular care has to be paid to the installation toprevent moisture absorption by the mineral oxide.

Fire resistance - System CircuitIntegrity - Reference Standards

DIN 4102-12- Fire behaviour of building materials and building

components - Part 12: Circuit integrity maintenance of electric

cable systems - Requirements and testing.This test foresees the

installation of cables in specically dened conditions, on ladder,

cable tray, ceiling installations, in a 3 meters long oven, for a period

up to 90 minutes, with a ame temperature that reaches 1000C. In

this case, the SYSTEM formed by cables and accessories is tested.

NBN 713.020- Protection contre lincendie - Comportement au feu

des matriaux et lments de construction - Rsistance au feu des

Code of practice and general standards

BS 5839-1:2002+A2:2008- Fire detection and fire alarm systems for buildings. Code of practice for system design, installation, commissioning andmaintenance. BS 5839-1:2002+A2:2008 provides recommendations for the planning, design, installation, commissioning and maintenance of redetection and re alarm systems in and around buildings, other than dwellings. It does not recommend whether or not a re alarm system should beinstalled in any given premises. Recommendations for re detection and alarm systems in dwellings are given in BS 5839-6. Cables are describedin clause 26. This standard introduces two different levels of resistance of cables during a re (standard and enhanced type) and many prescriptionsregarding installations. The standard cable must withstand the ame at 830C for 30 minutes, the enhanced type at 930C for 120 minutes.Besides the EN 50200 test, the cable must also get through specic BS tests, such as the BS 8434, that, however, will be gradually absorbed by theEN standards. New re tests are described in this standard, based on EN 50200, modied to include exposure to water spray. Even if BS 6387 is notexpressively called up, for standard cross reference anyway this standard is still required. Other standards of the same series are:BS 5839-6:2004- Fire detection and fire alarm systems for buildings.

Acid Gas Emission

The gases developed by the cables in case of re could be

corrosive. A cause for their corrosivity can be the emissionof halogensthat can be present either in the polymers thatform the cable insulation or sheath (PVC for example) or addeddisguised as anti-ame products.

There are mainly two systemsto measure how dangerousthey are. A system allows to measure the halogen contentsin the gas; the second one measures both the pHand the gasconductivity.

BS EN 50267- Common test methods for cables underfire conditions. Tests on gases evolved during combustionof materials from cables.This test allows to determine the

corrosivity of the acid gases, generally halogens, that developduring the electric cable combustion.BS EN 50267-1:1999Apparatus.

BS EN 50267-2-1:1999Procedures. Determination of theamount of halogen acid gas.This part of the standard denes

the method to measure the halogens quantity, by having thembubbling in a solution that is then titrated.

BS EN 50267-2-2:1999Procedures. Determination ofdegree of acidity of gases for materials by measuring pH and

conductivity.In this case the standard allows to measure thepH and the conductivity of a solution where are collected thegases developed by the combustion of the single materials

(insulation and sheath).BS EN 50267-2-3:1999Procedures. Determination of degree

of acidity of gases for cables by determination of the weightedaverage of pH and conductivity. In this case the standard allows

to calculate a weighed average of the measured value of pH,conductivity of a solution where the gases developed by the

combustion of the materials forming the cable are collected(normally insulation and sheaths).

BS 6425-1:1990 (SUPERSEDED) - Test on gases evolvedduring the combustion of materials from cables. Method fordetermination of amount of halogen acid gas evolved during

combustion of polymeric materials taken from cables.Thisstandard is no longer in force and is replaced by the BS EN

50267 standard.

BS 6425-2:1993 (SUPERSEDED)- Test on gases evolvedduring the combustion of materials from cables. Determination

of degree of acidity (corrosivity) of gases by measuring pH andconductivity.This standard is no longer in force and is replaced

by the BS EN 50267 standard.

The contents of this section is an overview of the problems related

to the state of the art behaviour of the electric and bre optic cables

in case of re. The picture is quite complex, both for the problems

critical state and for all the connections and prescriptions existing

between the various standards.

Deliberately we did not deepen this topic since this would require

many more pages and it would be useless in this context.

It is anyhow the position of Cavicel as far as the cable behaviour

in case of re in industrial plants is concerned; more detailed

technical information could be required any time at our Technical

Department.

Fire TestsCables have to be properlydesigned, manufactured and also tested.

Many tests are carried out during manufacturing or as nal inspections.

Many of them are attended by customers or third part inspectors.

The tests are part of R&D, an extremely strategic activity for a Company

and this is the reason why CAVICEL has invested in this eld.

You can nd here the maintests concerning the behaviour of cables

under re conditions, and our main test equipments.

It is important to verify all required performances and give the customers

the full compliance to the requirements.

CAVICEL is proud of its own laboratories and customersare always

welcome to visit them.




IEC 60331, CEI 20-36

Fire ResistanceThis test is carried out to verify circuitintegrity even during a re. A sampleof cable is held on a ame at about750C for a period of minimum 90min, under rated voltage. No breakor short circuit should occur. The

test can also be performed in moresevere conditions, up to 1100 C.Fibre optic cables can be tested insame conditions, monitoring theattenuation of the signal of one ormore bres.
