ISO International Standard

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).
