Ned,
I had this discussion with a TUV engineer way back in time. It is not in
the UL or IEC standards specifically AFAIK. What the TUV guy asked me to
do was consider the life of the product. The door hinge may have good
(low) resistance today
it said that
in the standard (IEC 60950-1 or IEC 60601-1). I looked and could not find it.
Am I just missing it, or is it not in the standards?
There is a reference in CSA standards to C22.2 No. 0.4 that has the
requirement, but I can not find a similar reference in UL or IEC standards.

Hi,
Does anyone know what is the directive for fire extinguishers. I checked
