Dear John, In IEC 60950-1 in clause 1.6.2 you can find following definition:
In each case, the readings are taken when the input current has stabilized. If the current varies during the normal operating cycle, the steady-state current is taken as the mean indication of the value, measured on a recording r.m.s. ammeter, during a representativeperiod.

I believe requirements in IEC 60065 are exactly the same. You need to use 1kHz source to verify what input signal amplitude results in output clipping. Then you need to set 1/8 of maximum non clipped output power with pink noise on input. Thank you, but I asked specifically about the *definitions* of the two terms, which I don't think are in the standards you mention. For example, 60065 uses the term 'non-clipped output power'. -- OOO - Own Opinions Only. With best wishes. See www.jmwa.demon.co.uk<http://www.jmwa.demon.co.uk> Quid faciamus nisi sit?
