How do you verify compliance of fiber optic cables to new
European CPR regulations for in-building applications?
1989 by European regulators, the Construction Product Directive (CPD), later
the Construction Product Regulation (CPR), was designed to ensure
materials and equipment that comprise buildings such as offices, schools, and
shops are safe from fire hazards and other risks.
Safety is top of
classification published in 2016 on how products such as communications cables
react to fire, a deadline for the mandatory CE marking of cables was set for
July 1st 2017. The European Commission mandates
construction materials like fiber optics have a common technical language like CPR
305/2011 for example.
facilities serving the European market will need to have been audited and
approved by Notified Bodies, and the building industry will be required to work
only with vendors that have carried out extensive testing with these Notified
Bodies, and can provide the proper Declarations of Performance for their
cabling products, organized in Euroclasses A to F.
This has been the
first ever pan-European implementation of a ‘hierarchy’ of cable fire
requirements. In order to demonstrate
specific class compliance, manufacturers must provide a Declaration of Performance
containing details about the Notified Body, and the applied verification system,
found in the applicable harmonized standard (EN50575).
will be required to carry the CE label appropriate to the applicable
Euroclassification. The type of testing
is determined by the type of verification system being used by the Notified
Body. Euroclass Cca and B2ca use the
most stringent verification ‘System 1+,’ requiring continuous audits and of the
production facility and product testing.
System 3 includes Euroclass Dca and Eca, which are lower safety classes.
80 percent of the Notified Bodies are accredited for System 1+ and can assign
Euroclass Cca and above. It’s important
for organizations to ensure they are using the appropriate Notified Body which
can be found on the NANDO website of the European Commission.
covers the full range of cables and performance across Europe, including single-mode/
multimode fiber cables, unshielded/shielded twisted pair cables and Category 6,
among others. All organizations
can ensure safety through compliance with EU cable regulations.
