Hello Richard,
This doesn't surprise me considering it has always been my philosophy that
complying with a safety standard does not guarantee that your product is safe.
There are always additional things to consider in evaluating a product's
safety beyond established standards. This is one reason

I've been away from NEBS for about a year, so my information may be dated..
As far as I know, there is no requirement for ejectors in GR-63 or GR-1089.
If it passes the office vibration and earthquake zone 4, then it is ok.
The real answer will lie with your customers. For example if
Richard,
The following is a cut and paste from GR-78, Issue 1, Sep-1997. I think it
answers your question. The R4-## are requirements and the IP4-62 is an
industry practice (meaning should do it this way not shall). This is a good
GR standard to have as it covers many of the generic practices.
I think those countries are part of the CB scheme but I advise checking the CB
website, http://www.cbscheme.org/

The ETSI standard series EN 300 019 defines a set of environmental tests
(storage, transport, etc) for telecom equipment. Can the standards be use
for medical equipment or do medical equipment have their own environmental
standards?

Hi Richard,
As far as I understand it, NEBS level 3 as defined in SR-3580
technically only references GR-1089-CORE and GR-63-CORE. I don't believe
there are any direct references to requirements for ejectors in them.
That being said, you should check GR-78-CORE (physical design - part of

Richard,
GR-78 Section 4.2.3 details Insertion and Removal Forces and specifies a
maximum of 32 pounds of force.
If you use two latches for insertion/removal, each latch is allowed 16 pounds
of force.
As you probably know, the only approval that makes a difference is from your
customers.
Hi Stone:
NEBS level 3 requires the product to comply with Earthquake
zone 4. If an ejector is required to remove the circuit card because
of the force required to extract it, you may have a better chance of
complying with Zone 4. (You don't want the circuit cards to fall out

hello all,
does anyone have an idea if the Nebs level 3 approval
has any information or a requirment on when an ejector
is required based on the force it takes to insert

some boards dont use or need ejectors,and some do.
is it based on satisfying any NEBS GR

Bill,
As LISN's can change over time you really should get the calibration factors
from the rental agency you are working with. If this is not feasible, you can
use the methods in ANSI C63.4 in which you can either use a Network Analyzer
