A while back I attempted to compile a list of standards (etc) that
generically address symbols /or markings. I omitted product-specific
standards which may reference, modify or complement these. May not be up to
date, please email me [directly] with any corrections if you wish and I can
repost.

In the case where a CDN is installed on each line from the EUT, how are the
signal line shields handled at the EUT - left unterminated, terminated to
ground, or terminated to the metallic case?

I'm sorry but I seem to have missed the purpose of this question.

I most sincerely hope that you are forced into justify these essential

Having lost sight of our objectives we redoubled our efforts.
I would like to know if there are significant differences between VDE701-1 and
IEC60990 with regard to test circuits for measuring leakage currents and touch
currents. Both IEC1010-1 and EN60950 both refer to test circuits which appear
to be derived from 60990.
Thank you,

Going back a ways, UL 1459, ed. 3 Sections 72 and 73 along with Appendix C
provide quite a lot of details regarding production line tests for telecom
equipment. I have not been able to find a reference within UL 1459 which
might indicate a deeper source of the requirements as reflected in
Sir
For some time, both UL and TUV have required my employer to test with a 25A to
40A current, depending on the branch circuit rating that the device can be
connected to (as specified in the Conditions of Acceptability). Also, CSA has

Good Morning John,
Visit the Safety Link www.safetylink.com and search (Control-F) on the
term ILSCO Wire Gauge Comparison Charts - Lots of good info there.
While at the Safety Link also search (Control-F) on the term wire charts
for resources provided by Alpha Wire.

EMC-PSTC'ers,
Where can I find a table(s) or list(s) of the preferred wire sizes
(electrical and otherwise) used in Europe, Japan, and other countries on
the metric system? I'm looking for:
* Names/numbers of standards.
* URL's for wire-manufacturer's websites.
* URL's for distributors'
Hi Folks,
I am looking for the best, but low cost, building material to cover a 6M X
8M OATS site.
Some years ago I used a test house who had purchased a facility made by a
conservatory manufacturer. Made from good quality plastic (UPVC?)
panels and plastic windows they had also
arranged
Dear all:
Can anyone kindly let me know how to decide what tests should be performed
for a DC module/product powered by USB port or PS2 port per EMC directive.
My thoughts are listed below:
EN55022 (Conducted Emission--yes; Radiated Emission--yes)
EN 55024
Table 1 --IEC 61000-4-6--yes, IEC
