ISO Technical Committee 22
Name	ISO Technical Committee 22
Abbreviation	ISO/TC 22
Formation	1959
Headquarters	Geneva
Type	International standards body
Parent organization	International Organization for Standardization

ISO Technical Committee 22 is an international technical committee responsible for developing standards in the field of road vehicles, bringing together experts from national standards bodies, industry consortia, and research institutions to produce consensus-based documents that facilitate interoperability, safety, and trade. Members include representatives from major automotive manufacturers, component suppliers, regulatory agencies, and testing laboratories who collaborate on harmonized standards impacting vehicle design, testing, and systems integration. The committee's outputs influence vehicle safety initiatives, legal frameworks, and global supply chains across multiple regions.

Overview

ISO Technical Committee 22 operates under the umbrella of the International Organization for Standardization, coordinating international standardization efforts that affect stakeholders such as Toyota, Volkswagen Group, Ford Motor Company, General Motors, Renault, Honda, Daimler AG, BMW, Nissan, Hyundai Motor Company, Stellantis, Bosch (company), Continental AG, Magna International, Aisin Seiki, ZF Friedrichshafen, Denso Corporation, Valeo, Lear Corporation, Faurecia, Johnson Controls International, Cummins Inc., PACCAR, MAN SE, Scania AB, Iveco, Tata Motors, Mahindra & Mahindra, SAIC Motor, Geely, Changan Automobile, BYD Auto, and Groupe PSA through national bodies such as British Standards Institution, Deutsches Institut für Normung, Association française de normalisation, American National Standards Institute, Japanese Industrial Standards Committee, Standards Australia, Standards Council of Canada, Bureau of Indian Standards, Korean Agency for Technology and Standards, China National Institute of Standardization, and Russian Federal Agency on Technical Regulating and Metrology.

Scope and Responsibilities

The committee's remit covers passenger cars, commercial vehicles, trailers, buses, motorcycles, and vehicle components, addressing topics that intersect with regulatory frameworks like those shaped by the Economic Commission for Europe, United Nations Economic Commission for Europe regulations, and safety programs linked to organizations such as Euro NCAP, National Highway Traffic Safety Administration, European Automobile Manufacturers Association, and International Transport Forum. Responsibilities include drafting international standards related to vehicle safety, emissions, electrical systems, braking, lighting, ergonomics, serviceability, and environmental performance, coordinating with bodies like International Electrotechnical Commission, ISO/TC 204, ISO/TC 184, ISO/TC 205, and ISO/TC 39 to align technical specifications that affect testing laboratories such as TÜV Rheinland, SGS (company), Intertek, Bureau Veritas, and DEKRA SE.

Organizational Structure

ISO Technical Committee 22 is organized into a plenary executive, subcommittees, and working groups that report to the secretariat hosted historically by national bodies including British Standards Institution and Standards Australia; the committee maintains liaisons with international organizations and industry consortia like SAE International, UNECE World Forum for Harmonization of Vehicle Regulations (WP.29), International Organization of Legal Metrology, World Health Organization, International Road Federation, Organisation for Economic Co-operation and Development, European Committee for Standardization, and European Commission directorates. Governance follows ISO procedures with chairs, secretaries, convenors, and project leaders coordinating ballot processes among member bodies such as AFNOR, DIN, ANSI, JISC, SABS, SNZ, and SIS.

Working Groups and Projects

Working groups under the committee address discrete technical domains including braking systems, occupant protection, electrical/electronic architectures, plug-in hybrid and battery electric vehicle standards, hydrogen fuel systems, advanced driver assistance systems, and cyber security for vehicles. Projects have engaged experts from research centers and universities such as MIT, Stanford University, RWTH Aachen University, Technical University of Munich, University of Michigan, Chalmers University of Technology, KTH Royal Institute of Technology, Politecnico di Torino, Tsinghua University, Indian Institute of Technology Kanpur, Tokyo Institute of Technology, and Seoul National University alongside industry test houses and regulatory laboratories to develop technical specifications, technical reports, and publicly available specifications.

Standards Developed

The committee has produced standards encompassing vehicle components and systems: specifications for brake performance, lighting and signalling, seating and restraint systems, occupant protection, electromagnetic compatibility, electrical connectors, vehicle emissions measurement, terminology, and dimensions. Many published standards are used in procurement, type approval, and certification processes by entities such as European Union, United States Environmental Protection Agency, Transport Canada, Ministry of Road Transport and Highways (India), and Japan Ministry of Land, Infrastructure, Transport and Tourism; these standards support harmonization with international test protocols used by test facilities like NHTSA Vehicle Research and Test Center and crash test programs such as Insurance Institute for Highway Safety.

Membership and Participation

Membership comprises participating (P) and observing (O) national bodies that nominate experts from manufacturers, suppliers, research institutions, accreditation bodies, and governmental authorities. National standards bodies such as ANSI, DIN, AFNOR, BSI, JSA, SABS, and SAC coordinate national positions and voting. Liaison organizations include SAE International, UNECE, CEN, and IEC, enabling stakeholders ranging from multinational corporations to independent laboratories like TÜV SÜD and Applus+ to contribute to consensus development.

History and Milestones

Since its inception in 1959 under the International Organization for Standardization framework, the committee has evolved alongside automotive technological shifts: standardizing mechanical components in the 1960s and 1970s, addressing emissions and safety in the 1980s and 1990s in dialogue with entities such as United Nations, European Union, and United States Department of Transportation, and advancing standards for electronic systems, alternative propulsion, and cyber security in the 2000s and 2010s. Milestones include publication of widely adopted specifications that influenced vehicle regulations and harmonization efforts with UNECE WP.29 and collaborative projects with SAE International, ISO/TC 69, and IEC to address emerging domains such as autonomous driving, electrification, and hydrogen infrastructure.
