Bob,
As you say, IEC 320 connectors are intended to be used for supplying ac
mains power.
Personally I would never advocate using a mains connector to supply 48 or
60 Vdc. There is a good chance that at some time in the product's life
someone somewhere will plug the equipment into a 'handy'

Hi,
For unintentional radiators, the FCC requires only verification. That
is, one has the product type tested at an approved lab and keeps
the data reports on file to verify that the product meets the Class A
limits.
Those verification reports must be produced if authorities need to see
them.
Does anyone out there have any information on the EMC and safety
requirements for products to be sold in South Africa?
From the limited information I have been able to find it appears that the
EMI requirements are based on CISPR 22 (no surprise). But are there
agency approval/certification

I appreciate to all those who have responded to my query on obtaining laser
information. Each lead has been, in process or will be, investigated
regarding the use of a laser product or system. Hopefully, in the near

I believe in the FCC book 47 CFR Sec. 15.103, titled Exempted devices is
what you are looking for.

Dear EMC-PSTC Members,
Who can shed some light on the MIL STD 810E and a so called 516.4
requirement?
What is it about, especially what does the 516.4 requirement mean?
Are IT Products in the scope of this Military Standard? If yes, to which
degree?
Many Thanks!
