ISO 14253-4:2010概述了ISO 14253-1建立的理论上理想的决策规则背后的主要假设。它讨论了为什么这些规则必须是默认规则，以及在应用不同决策规则之前应考虑哪些因素。 ISO 14253-4:2010适用于通用GPS标准（见ISO/TR 14638）中定义的所有规范，即ISO/TC 213制定的标准，包括工件规格（通常作为规格限值给出）和测量设备规格作为最大允许误差）

ISO 14253-4:2010 outlines the main assumptions behind the theoretically ideal decision rules established in ISO 14253-1. It discusses why these rules have to be the default rules and what considerations should be taken into account before applying different decision rules. ISO 14253-4:2010 applies to all specifications defined in general GPS standards (see ISO/TR 14638), i.e. standards prepared by ISO/TC 213, including workpiece specifications (usually given as specification limits), and measuring equipment specifications (usually given as maximum permissible errors).
