Joe - Your statement is not in all cases.
Please refer to GR1089, 4.5.3, R4-3, -4, -5, 4.6.1, and CR4-29 Although not a requirement, refer also to 4.5.13, Item 10, related to R4-18. Regards, Peter L. Tarver, PE Product Safety Manager Sanmina-SCI Homologation Services [email protected] -----Original Message----- From: Joe Finlayson Peter, NRTL Listing is not a requirement for CO equipment per GR-1089 although every one of our customers (CO's) requires it. You'd meet the requirements of the standards but you'd have a tough time selling it. Thx, Joe -----Original Message----- From: Peter Merguerian Tania, Your state that NEBS requires UL1950 safety testing. This may be true for CPE but not equipment sitting at the CO.

MERGUERIAN -----Original Message----- From: Tania Grant Michelle, I am providing you with a generic test matrix of several years back of an actual product that underwent NEBS compliance testing. I have stripped out any product references. Please note that test duration and cost will differ depending upon your particular product, and does not include any safety testing to UL 60950 even though this is also a NEBS requirement. Thus, the time and cost will increase. Also note that, depending upon your location, not all of these tests can be performed by a single test laboratory;-- you get to ship your product around. Be also aware that the same can happen even though the lab states that they will take care of everything (then they sub-contract it to other labs!). You will also need to have one or more of your people at the labs to assist in EMC immunity testing & ESD testing, to package and unpackage units/modules/equipment. Packaged tests require that certain parameters are tested prior to packaging (you need a viable product), then come the packaging stress tests, then you unpackage the equipment and repeat tests to see which parameters failed. Brutal it is, as Mike stated. The test duration increases as you find that certain parts of your product need to be redesigned. As was also previously stated, you need to make sure that the whole engineering team reads the GR-63 and GR-1089 standards and understands the requirements. No sense spending money on lab tests for obvious failures. Tania Grant [email protected] ----- Original Message ----- From: Michelle Cho Dear all, I need some help about something called NEBS(Network Equipment Building System). The whole procedure... What exactly the NEBS is and where can I do the testing? How much? How long does it take? Thanks in advance!
