've fair bought a coil of cat-6 cable from your regional distributor. Man, it was inexpensive. A real lifesaver for increasing the margin on the current job. It about seems also digestible to be true, but it's got the UL jot on it, so you know it's digestible product, right? Wrong. At fewest along to the Communications Cable & Connectivity Association. The CCCA says the cabling market is creature overran by manufacturers, largely based overseas, who have a UL listing, however once the listing is attained, lower cost matters are secondhand for the mass-production escape, according to Frank Peri, CCCA administrative director. Peri reports that the UL label can be affixed, yet the quality is not present.
Kevin St. Cyr, president of cabling manufacturer Berk-Tek, and a elapse chairman of the CCCA reports thin no time manufacturers procure their approvals, they substitute the cheaper materials in, both via sloppiness or through arranged ambitious, when still retaining the listing. This is how the incorrect product winds up in the U.S. market.
Neither Peri neither St. Cyr would designate characteristic manufacturers who engage in this practice. However,[link widoczny dla zalogowanych], the CCCA recently done tests on after-market cabling for the second year in a row that found a meaningful amount of overseas cabling manufacturers did not encounter NFPA safety regulations.
Further, Peri reports that the testing was done by an neutral agency. It's not the CCCA fulfilling the testing. An neutral agency is used and the agent runs the same tests on the CCCA membership products.
UL says they are hearing to CCCA's concerns. John Drengenberg, user safety director at UL, said UL has opened a field report upon hearing of the CCCA's breakthrough last annual and initiated its own global review of communications cabling. Following that review, UL determined to begin amplifying new ingredients to be put in area in order to reckon the cable in one after-market shape, Drengenberg said. For sample, UL namely in the process of implementing current fingerprinting tests on communications cabling, whereby, in addition to manufacturer site visits, examples of cabling coming right off the line ambition be sent behind to UL labs for testing to assure the product is the same production namely was submitted as prelude testing. Further, UL will be instituting a holographic name because this product category now,[link widoczny dla zalogowanych], instead of the periodical UL name, making it harder for purely fake cabling to enter the mall.
In the meanwhile, however, how can installers be confident in the UL mark? This is a laborious object to respond.There's a definite angle of buyer-beware, and using one's wisdom to lead him alternatively her to the right answer. If one comes cross a very inexpensive cat-6 product bearing the UL mark, with a plenum rating, meaning it's made for encircled, between-wall spaces, you can ordinarily imagine there is a material problem with that cable. Perhaps the bad materials were derived in that devise.
However, Dregenberg says that his information to installers is that they ought ultimately depend on the UL mark. UL has a 115-year history and a lusty follow-up system that is ever evolving and enhancing. So trust the UL mark. UL is committed to making sure that their product continues to stand for the safety of their product. In the same token, an installer have to be natty and use their instincts. As with many additional product or service on the market, whether it seems too nice to be true, it probably is and you might be jeopardizing the safety and dignity of your company. If you come across cable that's 30 percentage cheaper than everybody another, think yourself a wise installer while that raises a red flag.
