Counterfeit cables are an ever-present problem for the building
sector, so how can contractors avoid inadvertently falling foul of the
fakes?
Wire and cable industry body the IWCS held a webinar last week to
highlight the problem, with speaker Dave Kiddoo - executive director of
the Communications Cable & Connectivity Association (CCCA) noting
that counterfeiting has created "the potential for catastrophic fire
safety and critical performance consequences in building network
infrastructure."
Some sources estimate that as much as 20 per cent of the cable for
sale at any time may be unsafe, unapproved or counterfeit. A common scam
is to pass off inferior riser cable as Low Smoke Zero Halogen (LSZH)
cable, and it is also known that copper clad aluminium (CCA) cable has
been mis-sold as 100 per cent copper plenum (CMP) cables (Cat5e/Cat6),
which have fire retardant jackets and cannot actually cause fires.
Among the things to watch out for are cabling or packaging with
unauthorised UL, ETL or third-party certification marks – or indeed no
marks at all, according to the CCCA. Every box of UL-listed cable should
carry a holographic label, and it is important to watch out for
misleading and false claims such as CMP 'plenum-rated', CMP 'plenum
approved' or CMP 'plenum cable'
Earlier CCCA testing of counterfeit CMP cabling failed peak smoke
testing as well as the Average Smoke test. That's very important, as
rapidly spreading and heavy smoke makes it difficult to evacuate and
rescue occupants of a building.
Even packaging or cabling with authorised UL or ETL marks can be
counterfeit and non-compliant, according to the webinar, so it is
important to be mindful of other clues that all may not be above board,
particularly pricing below market norms.
Other warning signals can include private-label, unfamiliar brands
from offshore manufacturers, sometimes supplied only through a website
or local store front distributors, and poor English on company websites.
Kiddo recommends buying known brands but - if purchasing an unknown
brand is necessary - require written proof of listing or verification.
It is advised to use the websites of the listing agencies to see if any
public notices or recalls have been posted for that company name, but
purchasers need to be aware that counterfeiters' details may not yet be
in the database.
The CCCA has developed a smartphone app – called CableCheck – that
can be used as a field screening tool to check UL holographic labels.
