RE: GTEM cell

Careful -- for FCC emissions it's allowed only if correlation with an OATS is achieved for a given product. For the next product, correlation may have to be re-done. For immunity to EN's, it isn't so clear. IEC 61000-4-3 is written as if any type of TEM cell is NON compliant, but a draft annex

CSA C22.2 No. 950

Your question regards marking requirements. For safety standards only, you need only the CSA or C-UL mark with accompanying file number etc. For EMC markings (not a IEC 60950 issue) you may use something like the following: CANADA ICES-003, CLASS B (English) CANADA NMB-003,

Re: GTEM cell

Pingyu, I guess GTEM cell is a good choice for your case. Pls refer to IEC61000-4-3 (for immunity) and ANSI C63.4 (for emission), GTEM cell is not only recognized for pre-compliance test but also can be used for compliance test as long as some correlation can be achieved. We did correlation

CSA C22.2 No. 950

Could someone with a canadian version of the ITE 950 standard indicate whether or not they are aware of any additions to the marking requirements from that of the IEC 950 version. I have a copy of the IEC standard but would like to avoid purchasing the Canadian version, at least at this time.
