功率的测试有具体的条款在哪个章节?温升的我看过了,和你说的一样。 CL10.1 9 C* W; C Q1 Q' F( h1 U
If the power input varies throughout the operating cycle, the power input is determined as the 0 l7 y! V8 u& F- {

NOTE 2 The test is carried out at both the upper and lower limits of the ranges for appliances marked with one or ; I3 p( p8 e' b8 [

relevant voltage range, in which case the test is carried out at a voltage equal to the mean value of that range. |
