Colleagues,
I am advising on the design of a high tech oven to be used in the
semiconductor industry to anneal wafers. The main supply current will be far
in excess of 16 amps (in the hundreds, actually).

Don's approach does seem reasonable _if_ you build a simple R-L network to
provide some impedance to the power mains. A good stiff supply might make a
product look pretty good. Another thought is to look at the mains supply
current for bumps and calculate what voltage would be created across t
I am looking for suggestions for European standards with regard to ladders
and maintenance platforms. I have a copy of British Standard BS 5395: Part
3: 1985. "Stairs, ladders and walkways" and was wondering if there might be
other applicable European standards.
Thanks in advance

Interesting discussion on FCC Verification of OEM ITE equipment.

be fitted externally onto an existing power supply to enable it to pass the EN

A very rough guide might be to observe the 230 V on the mains and see if
your product causes it to dip a few volts momentarily (or do an analysis to
determine worst case dip and frequency of dip). If it doesn't dip at all,
you have no need to measure per 6.1.
If the mains voltage do
Hi Group,
The unit I am looking at purchasing is from EMC Partner, model TRA2000 with
Surge and Dips capability. I am located in western Canada and have only
spoken to 1 user of the equipment in North America (has only had the unit
for a couple of months and has not used the surge function). T
Barbara,
While not definitive I believe the scope section of the standard describes a
few likely devices. I don't have the standard in front of me, but seems I
remember seeing it that section.

I suggest contacting ITL in Israel; their web page is:

The recent Conformity Update on a possible new SAR standard stated:
"The existing standard, say the manufacturers, is interpreted differently in
different countries and may not measure what it is purported to measure, that
is, the conversion of radiated energy into heat by biological tissue."

To all who responded, many thanks.
It appears that company A and company B must understand the responibilites
of future compliance issues and be able to document the testing standards
used and revision dates. I did not mention CE compliance but believe the
above also applies.
Best regards,

Hi Group,
We currently hold various Narrow Band(450-470MHz) licenses. Since it is
simple we renew them as required instead of letting them expire. However, I
