I have read many specification sheets for speaker drivers from various manufacturers and they all list some measurement of the driver's power handling capability. The most common way of defining this parameter seems to be the listing of two wattage measurements: RMS and Maximum (or Peak). RMS, as I understand it, is the measurement that defines the watts that the driver will tolerate in an extended period, while Maximum defines the watts tolerated in an instantaneous peak. Some companies deviate from this specific terminology but still present the same measurements---Seas, for example, lists "Short Term Power Handling" and "Long Term Power Handling" which clearly refer to Peak and RMS respectively.
But what is to be made of the Peerless/Tymphany "Rated Noise Power"? All the spec sheets from this company that I have read list this parameter, and the web site shows it referenced to the IEC 268-5 18.1 standard. What does this number represent? Is it RMS wattage? Is it peak? Is it something else? I am hoping that a more knowledgeable member who knows for certain what this number is can clue me in. Thank you.

All fairly useless specs, as there is no standard for defining this. Often from the marketing department.

Thanx. I hadn’t seen that. Or manufacturers noting it.
Any idea of those that use it.specify based on it?

Letting the smart *** in me get hold for a second...
Average power before hearing damage?
Reasonable explanation and some comparison graphs here
Speaker power handling
A rating for no appreciable damage after 100 hours of the test signal which is band limited pink noise with a 6dB crest factor, intended to resemble music.

Thanks to fluid for the link. Before my initial post I had searched for the IEC 268-5 standard but could only find a limited description that was not helpful. Your post answered my question.
