关于厨具类的11章测试条件的一些讨论。
# F4 z- q" q* | R5 g& W. p7 w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

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

所以,11章的测试条件要结合10.1功率输出的结果来确定。! d8 v) j3 t+ T' t. J/ \2 [% i/ m- [, Y

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# D6 t6 \4 v. Q1 q* ~. U

5 v, N( |% y% K5 d5 _* v另外,以切片机为例子,假设说明书规定KB为5min,测得额定功率为最不利条件,那么参照11.7.101,切片机在额定功率下工作30min,如果温升不超表3即可,如果超过,又该怎么做?测试时间为5+1= 6min? 是否需要做循环?还是在额定功率下工作6min一个循环?5 E; \. g1 e: d/ D) E a5 U
