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

Tania,
Your state that NEBS requires UL1950 safety testing. This may be true for
CPE but not equipment sitting at the CO. Please correct if I am mistaken.

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.

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!
Michelle
