Welcome to ISO/TC 213 

 

ISO/TC 213 is responsible for international standards relating to the tolerancing, specification and verification of mechanical components. This includes standards for geometrical tolerancing (ISO 1101), datums (ISO 5459), size tolerances (ISO 14405), coordinate measuring machines (CMMs) (ISO 10360 series), and many, many others. 

Industry in Europe, the USA, Japan, China and across the world relies extensively on these standards. They are used in the design and manufacture of aircraft, cars, consumer products, medical devices, energy systems, defence hardware, scientific instruments, and in pretty much every area of industrial activity. 

 

Who are we? 

ISO/TC 213 is the international committee responsible for creating, updating, and maintaining the ISO GPS standards for geometrical product specifications and verification.

The committee was created in 1996 under the leadership of Danish Standards who ran the area for 21 years. The UK - BSI - took over the secretariat of the committee in 2017.

Introduction to the ISO/TC 213 standards - the ISO GPS system

ISO GPS (geometrical product specifications) is an internationally accepted concept covering all of the different requirements - indicated on a technical drawing - for the geometry of industrial workpieces (e.g. size, distance, radius, angle, form, orientation, location, run-out, surface roughness, surface waviness, surface defects, edges, etc.). It includes all related verification principles, measuring instruments and their calibration. Expressed more simply - it is all of the requirements specifying the micro and macro geometry of a product (workpiece) with associated requirements for verification and calibration of related measuring instruments.

Who develops ISO standards?

 

Want to get involved?

Standards are developed by the people who need them – that could mean you. Technical committees include experts from both standards and industry and these experts are put forward by ISO’s national members. If you want to help shape future standards in your field, contact your national member
