41、s of the following parts, under the general title Geometrical product specifications (GPS) Dimensional measuring equipment : Part 1: Plain limit gauges of linear size Part 2: Reference disk gaugesThis part of ISO 1938 does not include requirements for setting plug gauges and setting ring gauges, whi
42、ch were dealt with in ISO/R 1938:1971, 3.9.4.This part of ISO 1938 covers the concepts and principles developed in ISO 14978.DIN EN ISO 1938-1:2016-03 EN ISO 1938-1:2015 (E)4 IntroductionThis part of ISO 1938 is a geometrical product specification (GPS) standard and is to be regarded as a general GP
43、S standard (see ISO 14638). It influences chain links E, F and G of the size chain of standards in the general GPS matrix. For more detailed information of the relation of this part of ISO 1938 to other standards and the GPS matrix model, see Annex C.The ISO/GPS matrix model given in ISO 14638 gives
44、 an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated.The terms and c
45、oncepts used in this first edition of ISO 1938-1 (compared to the former edition ISO/R 1938:1971) have been changed according to needs and terminology in the other GPS standards.This part of ISO 1938 deals with verification, using plain limit gauges, of linear sizes for features of size when the dim
46、ensional specifications are required (see ISO 14405-1), for rigid workpieces.NOTE Tables 4 and 5 use the modifiers given in ISO 14405-1 and ISO 1101.DIN EN ISO 1938-1:2016-03 EN ISO 1938-1:2015 (E)5 1 ScopeThis part of ISO 1938 specifies the most important metrological and design characteristics of
47、plain limit gauges of linear size.This part of ISO 1938 defines the different types of plain limit gauges used to verify linear dimensional specifications associated with linear size.This part of ISO 1938 also defines the design characteristics and the metrological characteristics for these limit ga
48、uges 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 part of ISO 1938 describes the use of limit gauges. It covers linear sizes up to 500 mm.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
