Hi John:
Because continuity at low current does not ensure that the protective
circuit will carry a large fault current - it might be 'hanging on by
one strand'.
Yes, for one strand. No, for five strands.
Some years ago, I did some experiments on what
problems the 25-amp test
Greetings all,
I am looking for recommendations for a NEBS environmental test lab
that has an operational temp/humidity chamber of significant size and
with tremendous cooling capacity (8kW or more). I have a large

Sorry, once again ham fisted typing lead to C64.5 rather than the proper
C63.4 - my error hope it didn't confuse to many folks. Thanks for
straightening that out.

Part 18 still uses MP-5 but it is not mandatory. In cases of dispute, MP-5
will be used by the FCC. You can't go wrong, however, using ANSI C63.4 as
the test set-up. Or you can use the CISPR limits as Gary described. I do
not know what C64.5 is.
You do not have to submit your test results

Hi Dick,
The requirement for using 10 to 25 Amps comes from the test house. It is
their mark. If you want to use it, they can require you to do anything they
want. Is it fair, no. Does the requirement make engineering sense, no (I

I am interested in purchasing some new/used test equipment. I am looking
specifically for a 'Digital Balance Analyzer' and an 'AC Stress/Hazardous
Voltage/Hazardous Current Analyzer'. Any suggestions would be appreciated.

You mentioned the CTL Decisions. While I understand that not all the
decisions have been placed on the web yet, you will find many of them

Pierre, MP-5 isn't relevant any more. I believe you want ANSI C64.5.
and I think you'll find mostly similarities. I can't think of any
dissimilarities of the top of my head, Even FCC part 15 allows use of the
CISPR limits for radiated and conducted

Is there a European standard for Li-ion batteries?
Is there a battery directive? If yes, what standards is applicable?
