首先，测试条件的选择，在标准的3.1.9明确定义了各种器具的正常工作，但是标准的后面有一句(红色标注部分), 而下面的NOTE 103就解释了在哪种偏差下，额定功率是最不利条件
operation of the appliance under the conditions specified in 3.1.9.101 to 3.1.9.119, or at rated power input if this is more unfavourable
NOTE 103 Operation at rated power input is considered to be more unfavourable if the power input determined during the test of 10.1 differs from the rated power input by more than
–20 % for appliances having a rated power input not exceeding 300 W;
–15 % (or –60 W if greater) for appliances having a rated power input exceeding 300 W.
所以，11章的测试条件要结合10.1功率输出的结果来确定。
其次，测试的时间的选择。11.7.101--11.7.117明确说明了各类器具的工作时间。但是在2-14的11.7有一段文字
If this period exceeds that stated in the instructions and if the temperature rise limits of Table 3 are exceeded, the test is carried out for the number of cycles specified and using the maximum quantity of the load to be processed stated in the instructions for
? the maximum period stated in the instructions plus 1 min, for specified operating periods not exceeding 7 min;
? the maximum period stated in the instructions, for specified operating periods exceeding 7 min.
If it is necessary to perform a number of operations to obtain these periods, the rest periods are equal to, where relevant, the time taken to empty and refill the container with the maximum quantity of ingredients stated in the instructions.
Appliances incorporating a timer are operated for the maximum period allowed by the timer.
