Peter,
Think about why the standards define normal
environment (temperature, humidity,
airpressure,etc.)conditions when performing
a test.
Those environment parameters will cause the
frequency to shift, cause the amplitude to
change, etc..A simple example, when the
emperature increases, the

The voltage of the neutral with respect to the ground wire

Maximum normal current is the rating of the fuse or circuit-

circuit in the USA and Canada, the

ETSI recently placed all their specs on the web for free download.

Your FCC part 15 for emission is mutually recognized by Canada. As for
Safety, US has UL1950 3rd Ed. while Canada has C22 NO. 950. These safety
tests are almost identical with some dela. You need to get the Canadian

vendors. Each came with a ferrite in the box, together with
instructions as to how to loop the phone cable through it, and a warning

I don't think a CE mark is required for the stand. However, you may have to
test your product as it is installed on the stand. The particular tests I
am thinking of are the 10 degree tip test and the xx Newton sideways push
force test. Does the product tip over in either of these two tests? If
