John, I won't be in my office until until Monday morning to look up the specific references. And I'm familiar with the method used to determine the power or current rating of an audio amplifier but I assume there is one. The term "steady state current" has been used for many years in IEC standards I deal with such as the IEC 60950 and IEC 61010-1. I never gave it much thought if the term is an official IEC defined term or not.
Again, I don't have my references in front of me but "max continuous current" is defined in the US National Electric Code in regard to the 125% rule on plugs. We deal with this issue often with NRTLs and with Canada.

It should be defined in clause 1.2. In any case, the test method is not suitable for audio amplifiers, which are not in the scope of 60950-1. I hope someone will tell me where 'continuous input current' is defined. -- OOO - Own Opinions Only. With best wishes. See www.jmwa.demon.co.uk<http://www.jmwa.demon.co.uk> Quid faciamus nisi sit?
