I agree with Stephen, except that I would exert a great deal of my energy to
have this corrected by the power supply manufacturer, -- and fast! The
manufacturer is in danger of loosing your business unless this gets
resolved.
Try to resolve this in parallel, assuming it is the same NRTL:

EN 45014:1998 specifies the General criteria for supplier's declaration of
conformity. Concerning the identification of standards, the document says
the DoC shall contain the referenced normative documents in a precise,
complete and clearly defined way . . . The example of a DoC in Annex A
TUV Rheinland is heavily involved in automobile testing in Germany. You

Chris,
I have researched this topic recently. There are apparently no requirements
at the national level. The Dept of Fair Trading of New South Wales has
authority over product safety in that state. Fundamental requirements can be
found in ELECTRICITY SAFETY (EQUIPMENT SAFETY) REGULATION 1999.
Hi,
I have been volunteered to research the Automotive EMC Directive. What I
have found so far is,
- The directive is 95/54/EC which is an amendment to 72/245/EEC.
- The directive is an old approach and has all of the necessary test
procedures and methods in the directive.

Chris,
My point was EUT-related, not spec-related. You must perform FCC conducted
RF emissions testing with the correct US mains interface, or be prepared to
justify that the 230V test results are sufficiently equivalent (e.g. based
on past history).
Your point on limits is valid, but moot if
NEBS Tested does not mean NEBS Compliant!

The class B FCC limits for conducted disturbance at the mains ports are
lower than EN55022 class B.
QP limits:
FCC - 0.45 to 30MHz = 48dBuV
EN - 0.15 to 0.5MHz = 66 to 56dBuV (decreasing linearly with the log of
frequency)
0.5 to 5MHz = 56dBuV

Chris,
Here is my 2 cents worth:
1. For ITE such as a computer or router (without a connection to a
telecommunication network), the applicable standards and requirements are
AS3260 (safety) and
AS3548 (emc) and the manufacturer applies the C-Tick Mark (ie for EMC
Compliance). EMC is mandatory,
The Hendry power supplies displayed at the NEBS 2000 symposium in Las Vegas
all bore NTS NEBS Tested labels.
