产品的合格与否,直接关系着一个企业的经济效益和社会效益。把一批产品误判为不合格品,无疑将使企业经济效益蒙受损失;反之,把不合格判为合格品,又将使用户遭到损失,使社会效益受到影响。当一批产品既不能完全接收,又不能简单的拒收时,则应对这批产品的不合格品率 Whether the product is qualified or not is directly related to the economic and social benefits of a company.

When a batch of products cannot be fully received and cannot simply be rejected, the unqualified product rate of this batch of products should be dealt with.
