ISO/TC 213/WG 6 - General requirements for geometrical product specification (GPS) measuring equipment

This document provides the most important design and metrological characteristics of micrometers for external measurements: — with analogue indication; — with digital indication: mechanical or electronic digital display.

This document specifies the most important design and metrological characteristics of calliper depth gauges — with analogue indication: vernier scale or circular scale (dial); and — with digital indication: digital display.

This document provides the most important design and metrological characteristics of callipers — with analogue indication: vernier scale or circular scale (dial), and — with digital indication: digital display.

This document specifies the general requirements, calibration, terms and definitions of characteristics of GPS measuring equipment, for example micrometers, callipers, gauge blocks and rotary axis form measuring instruments. This document forms the basis for standards defining and describing the design characteristics and metrological characteristics for measuring equipment and gives guidance for the development and content of standards for GPS measuring equipment. This document is intended to ease the communication between manufacturer/supplier and customer/user and to make the specification phase of GPS measuring equipment more accurate. This document is also intended as a tool to be used in companies in the process of defining and selecting relevant characteristics for measuring equipment. This document includes terms which are frequently used in connection with the characterization of specific measuring equipment.

ISO 1938-2:2017 specifies the most important metrological and design characteristics of reference disk gauges. ISO 1938-2:2017 covers linear sizes of the gauge up to 500 mm.

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.

ISO 13102:2012 specifies the most important design and metrological characteristics of electronic digital-indicator gauges.

This International Standard specifies the most important design and metrological characteristics of height gauges (with analogue indication or digital indication) for linear-dimensional measurements perpendicular to a surface plate.

ISO 9493:2010 specifies the most important design and metrological characteristics of dial test indicators (lever type).

ISO 463:2006 specifies the most important design and metrological characteristics of mechanical dial gauges.

ISO 13385-1:2011 provides the most important design and metrological characteristics of callipers with analogue indication [vernier scale or circular scale (dial)] and with digital indication (digital display).

ISO 13385-2:2011 provides the most important design and metrological characteristics of calliper depth gauges with analogue indication [vernier scale or circular scale (dial)] and with digital indication (digital display).

ISO 3611:2010 specifies the most important design and metrological characteristics of micrometers for external measurements: with analogue indication; with digital indication: mechanical or electronic digital display.

ISO 14978:2006 specifies the general requirements, terms and definitions of characteristics of simple GPS measuring equipment, e.g. micrometers, dial gauges, callipers, surface plates, height gauges, gauge blocks, but not necessarily excluding more complicated equipment. It forms the basis for standards defining and describing the design characteristics and metrological characteristics for measuring equipment. It also gives guidance for the development and content of standards for GPS measuring equipment. ISO 14978:2006 is intended to ease the communication between manufacturer/supplier and customer/user and to make the specification phase of GPS measuring equipment more accurate. It is also intended as a tool to be used in companies in the process of defining and selecting relevant characteristics for measuring equipment to be used in the quality assurance of measuring processes, i.e. in calibration and in workpiece measurements. ISO 14978:2006 also includes terms which are frequently used in connection with the characterization of specific measuring equipment.

Specifies the most importent dimensional, functional and quality characteristics for measurements. Table 1 covers parameters for the measuring ranges from 0 mm up to and including 500 mm which are devided in steps of 25 mm each. Annex A refers to measurement errors within the measuring range; annex B contains instruction for application; annex C includes recommendations for testing.
