This Japanese Industrial Standard specifies the procedures of determining and operating single, double, and multiple sampling inspection plans by attributes expressed in terms of the number of defectives or defects with severity adjustment. Further, this applies to the case where a series of lots is submitted successively to receiving inspection and suppliers can be selected.
