ISO 14253-1:2013规定了对于工件（或工件数量）的特性给定公差或测量设备的计量特性的最大允许误差限制，确定合格性或不合格性的规则，同时考虑到测量不确定度。 这些规则对于单个工件的公差和工件种类的公差是不同的。 它还规定了如何处理不能采取明确决定（符合性或不符合规格）的情况，即当测量结果落在规格限制附近存在的不确定范围内时。 ISO 14253-1:2013适用于通用GPS标准中定义的规范（见ISO/TR 14538），即由ISO/TC 213制定的标准，包括: ？工件/工件总体规格（通常以上限公差或较低公差极限或两者兼作）; ？测量设备规格（通常以最大允许误差给出）。 ISO 14253-1:2013仅适用于以数值表示的特征

ISO 14253-1:2013 establishes the rules for determining the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or limits of maximum permissible errors for a metrological characteristic of a measuring equipment, taking into account the measurement uncertainty. These rules are different for tolerances to individual workpieces and tolerances to workpiece populations. It also gives rules on how to deal with cases where a clear decision (conformity or nonconformity with specification) cannot be taken, i.e. when the measurement result falls within the uncertainty range that exists around the specification limits. ISO 14253-1:2013 applies to specifications defined in general GPS standards (see ISO/TR 14538), i.e. standards prepared by ISO/TC 213, including: ? workpiece/population of workpieces specifications (usually given as an upper tolerance limit or a lower tolerance limit or both), and; ? measuring equipment specifications (usually given as maximum permissible errors). ISO 14253-1:2013 only applies for characteristics expressed as numerical quantity values.
