1. Do I have to install a Euroclass Compliantdata cablingin data cablinginstallation
Euroclass cables and data or fibre optic cabling inwhich these standards are affected?
Euroclass cable
The requirementtoinstall aEuroclass cable isto be compliantwith BS6701:2016+A1:2017
Therefore if youare not installingtothisstandardthenthe non-compliance isadvisedtobe notified
to the buildingowner.Insuchcasesa fire safetyreportcanbe undertakenunderBS9999 to lookat

What is CPR?
Specificallythe ‘ConstructionProjectsRegulation’aimstobreakdowntechnical barriersandprovide
a commontechnical language.Thustoassessthe performance of constructionproductsandto
harmonise the rules formarketingthese products.
Four KeyConceptsof CPR:
A systemof harmonisedtechnical specifications
A frameworkof notifiedbodies
A systemof conformityassessmentforeachproductfamily
2. CE markingof products
Whyis LS0H no longer enough?
Low-smoke,zero-halogen(LS0H) cablesweredesignedtomeetthree IECstandards:
1. IEC60332: Flame Spread
2. IEC60754: Smoke Acidity
3. IEC61034: Smoke Emission
The CPR appliesadditional criteriaandtestingprocedurestopromote amore harmonisedstandard
to describe acable’sreactionto fire.
Are all cable types requiredto comply?
The CPR appliestoall permanentlyinstalledcableswithinabuilding;communication,power
and control cablesinfixedinstallations.
There isno distinctionbetweencopperand fibre,orshieldedandunshieldedcables.
The onlyexceptionispatchleads,whichare notwithinscope of CPR.
So, which CPR Euroclass Cable shouldyou choose?
DifferentMemberStatesrequire differentCPRclassificationlevelsforvariousapplications.
Furthermore memberState mayimplementthe standardinline withtheirregional requirements.
For instance,hospitalsrequireaB2ca ratingin some countries,butonlyaCca rating inothers.
In thiscase to achieve standardscompliance inthe UK,itis importanttochoose a cable witha CPR
Euroclassof a minimumof Cca,s1b, d2, a2 - as stipulatedinBS6701:2016+A1:2017.
Likewise thisappliestoanynewinstallationsorthe refurbishmentand/orextensionof existing
installationswithinthe external firebarrierof the building.
Therefore itisalwaysadvisabletoalwayscheckwithacountry’slocal regulations.
