Scope
GB/T 18779的本部分给出了当GB/T 18779.1的缺省规则可能在经济方面不是最优的情况下的判定规则。
注1：GB/T 18779.1提供了一个缺省判定规则，按照该规则，如果测得值表征接受某产品，则具有很高的概率可以保证，该产品的相应被测量符合规范。
注2： 将判定规则由缺省规则改成针对特定任务的规则，需要有关双方达成协议。
本部分不涉及如何确定正确判定或错误判定的成本(“正确判定”是指接受合格品或者拒收不合格品，“错误判定”是指接受不合格品或拒收合格品)，因为这是商务事宜。然而，本部分给出了组织机构所需的术语和要求，用于沟通和执行特定的判定规则，同时给出了指导应用的示例。
注3： 本部分判定规则适用于处于考虑中的单一计量特性。除非另有说明，本部分所讨论的所有概率分布均为高斯分布且位于中心位置，而且成本函数是简单阶跃函数。然而，本部分的原则可应用于任何概率分布函数或成本函数。
本部分适用于产品几何技术规范中工件与测量设备的测量检验，工业应用中也同样适用。
