I have a client that manufacturers a wireless security product. It operates
on either 303.875 MHz or 433 MHz at 1mW, approximately 100 meter range, just
short burst tranmissions (once per hour, 5 seconds per burst). The device is
compliant with FCC in the USA. What are the approval require
I'm interested in acquiring United Kingdom (Britain) AC and DC power
standards for designing and installing AC and DC power systems.
1. Do you know where I can find or acquire United Kingdom standards
for AC power and DC power?
2. Is there an equivalent United Kingdom electric code similar to

No kidding, you may use MOV's for surge suppressing between phases, but not
connect it to ground for the reasons above.
You may use MOV

This rumor doesn't make much sense as an across-the-board requirement,
especially considering UL has a component product category for MOVs and
other transient voltage surge suppressors, along with some product standards
that allow reductions of over-surface and through-air electrical spacin

If you haven't done so already, you might try ANSI/AAMI standard DF-39
"Automatic External Defibrillators and remote control defibrillators". I
used it a long while ago when testing the surge immunity of an implanted
device. I don't remember the design specifics of the standard, because I

I recently received an e-mail from a colleague on the east coast
stating that UL has joined TUV Rheinland in NOT accepting the use
of MOV's in primary circuitry.
The reasoning behind this is due to the unpredictable dielectric
break down of these components which ca
I believe that this question is too general. In general, I would not feel
comfortable not doing 100% dielectric testing, but you must look at your
particular construction to figure this out. For instance, refer to table 6A
concerning insulation in printed boards. Most cases require 100%, or R

Has anyone worked on defibrillators?
My slight reading on the subject has found widely differing limits.
And the milli-amp spec is from the hand only. Especially
the right hand. One reason why long ago, I was taught to work on

I'm doing radiated emissions testing via CISPR14, which uses an RF
clamp around the power cord to measure radiation.
The clamp is described in CISPR16-1:1993, Clause 13.
Rohde & Schwarz sells such a device, but I'd like to compare prices
with another vendor.
Are there other vendors out there, or
