ISO的实验样本方法

rachelzhou

某外国的公司对我们产品的微生物要求，可是有部分我不太看得懂：m=Microbiological limit that:
-in a 2 class plan separates good from defective quality;
-in a 3 class plan separates good from marginally acceptable quality.
M=Microbiological limit that:
-in a 3 class plan separates marginally acceptable from unacceptable quality;
-in a 2 class plan M may be assimilated to m.
请教大家！

猜一下跟国标限量里面的M,m差不多，可以参考这个帖子http://bbs.www.sqrdapp.com/thread-325948-1-1.html

参考一下，微生物二级和三级取样标准是否类似
