c=0抽样方案是由Nicholas L. Squeglia开发的。 本书说明:
1. 抽样方案表1声明"associated AQLs"。意思是说与ANSI Z1.4抽样方案相关联的AQL。表中的 "associated AQL"只是一个索引值, 但不是AQL。
2. 使用“扣留批次”术语。"扣留批次”这个词语意义重大,并不一定就是拒收。 根据这些计划,如果发现一个或多个不符合项,检查员不会自动拒收批次。
"The c=0 plans in Table 1 are “associated” with the AQLs of ANSI Z1.4. In all of these plans, the protection afforded to the consumer is equal to or greater than the ANSI Z1.4 plans. This method of developing the plans provides for simple conversion from the ANSI Z1.4 plans to the c=0 plans. Table 1 labels these associated AQLs as “index values” because, of course, they are not AQLs."
"The phrase “withhold the lot” is significant in that it does not necessarily mean rejection. Under these plans, the inspector does not automatically reject the lot if one or more nonconformances are found."
