Hi Don, >The requirement for most customers, especially telecommunications providers, >is that the product be LISTED or RECOGNIZED to comply with the safety >standards of concern. The most important being UL1950 and NEBS. To be >listed and participate in continuing compliance (required) you must use the >logo of the certification laboratory, such as ETL, MET, UL, etc. The >listing number is also required in close proximity to the logo. (Since this >is a legal requirement with the lab, it is a "badge of quality" on the >product, which should be appreciated by your marketing department!) All true. However, as to the listing number, different NRTLs require/recommend different designations. UL, for instance, requires the word "LISTED", an assigned control number along with a product identity marking (e.g., ITE, NWGQ, etc.). I'm sure that the other NRTLs have similar marking requirements other than just the use of their mark. And, as for quality, continued use of a NRTL mark means only that the product is continuing to be built according to how it was written up into the report, nothing more. I have seen many many instances where reports have been simply wrong, incorrect, and in one case a while back, negligent (I will offer no further information about any of these instances). >I am told that there are changes "afoot" to allow manufacturers to self >certify to these requirements, however my experience shows that most of our >customers will not accept self certification. IMHO, I don't see self certification in the US happening any time soon, if at all. Even if it did, there would be at least 2 federal regulators (OSHA & NEC) to change their reg's, and not to mention the thousands of municipal authorities. Of course, to align with the EU-US MRA, that might actually happen, but not in the near future or in my lifetime. But, I could be wrong.
