ISO 14253-1:2017规定了对于工件（或工件群体）的特征的给定容差或对于测量设备的计量特性给定的最大允许误差的合格或不合格的规则，包括何时测量值接近规格限制，考虑到测量的不确定性。 ISO 14253-1:2017适用于通用GPS标准（见ISO 14638）中定义的规范，即由ISO/TC 213制定的标准，包括: - 工件规格和总体规格（通常作为规格上限或规格下限或两者）; - 测量设备规格（通常作为最大允许误差给出）。 ISO 14253-1:2017仅适用于以数量值表示的特性和最大允许误差。

ISO 14253-1:2017 establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or with a given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measured value falls close to the specification limits, taking measurement uncertainty into account. ISO 14253-1:2017 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including: - workpiece specifications and population specifications (usually given as an upper specification limit or a lower specification limit or both); - measuring equipment specifications (usually given as maximum permissible errors). ISO 14253-1:2017 only applies for characteristics and maximum permissible errors expressed as quantity values.
