Geometrical product specifications (GPS) - Dimensional measuring equipment - Part 1: Plain limit gauges of linear size (ISO 1938-1:2015)
ISO 1938-1:2015 specifies the most important metrological and design characteristics of plain limit gauges of linear size.
ISO 1938-1:2015 defines the different types of plain limit gauges used to verify linear dimensional specifications associated with linear size.
ISO 1938-1:2015 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, ISO 1938-1:2015 describes the use of limit gauges. It covers linear sizes up to 500 mm.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT), see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 213, Geometrical product specifications and
verification.
This first edition cancels and replaces ISO/R 1938:1971, which has been technically revised.
ISO 1938 consists 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 gauges
This part of ISO 1938 does not include requirements for setting plug gauges and setting ring gauges,
which 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.

Introduction
This part of ISO 1938 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS 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 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.
