Now it is a little more work than that. Last one I was involved in we did a
quick and dirty temperature test, dielectric, ground bond and visual inspection
to ensure proper fusing, the power switch breaks line, PE is green
yellow/green, etc. The inspection takes about 2 hrs then the report is
Thank you for responses I've received. They've been very helpful.

Bob,I believe that document may be on the Product Compliance online communities site. Unfortunately most of the IEEE web servers are down because of the storm so I cannot verify.The URL is http://product-compliance.oc.ieee.org/ and you need an IEEE account to view it. An IEEE account is available

In addition to the electrical code requirements under the Canadian Electrical
Code (CEC), CSA C22.1, and the applicable parts of the CE Part 2 standards (CSA

Esteemed Colleagues,
I have a product submitted to NRTL E that uses a Mylar electrical barrier
between line-voltage (120 V ac), uninsulated live parts on a circuit board and
the aluminum electrical enclosure. The 'through-air' spacing would be a little
short without this barrier in place. The

Hi Tom,
That symbol is a China RoHS marking found in document SJ/T11364-2006 issued by
the MII where the specifications for that symbol are given. This symbol's
intent is to indicate a product to be environmentally friendly.
IHTH.
Best regards,
Ron

Tom,
The logo is the China RoHS Environment Friendly Use Period logo - it should
be green if the substances are all under the limits or not present, and It
would be orange if any of them were above or if you did not know, with a
number inside where the e is. That number would be a manufacturer
Hi Richard:
Unfortunately, this situation mixes two, independent
requirements: 1) electrical insulation requirements,
and 2) anti-fire requirements.
If the clearance (air insulation) is insufficient for
basic insulation, then a solid insulation may be used
in place of the clearance.
