This document specifies requirements for the most important metrological and design characteristics of plain limit gauges of linear size. This document defines the different types of plain limit gauges used to verify linear dimensional specifications associated with linear size. This document also defines the design characteristics and the metrological characteristics for these limit gauges as well as the new or wear limits state maximum permissible limits (MPLs) for the new state or wear limits state for these metrological characteristics. In addition, this document describes the use of limit gauges. It covers linear sizes of up to 500 mm.
