ISO/IEC AGREEMENT CONCERNING STANDARDIZATION OF
ELECTROTECHNOLOGY FOR ROAD VEHICLES AND THE COOPERATION
BETWEEN ISO/TC 22 “ROAD VEHICLES” AND IEC TECHNICAL COMMITTEES
The allocation of work between IEC and ISO is based on the agreed principle that all questions relating to international standardization in the electrical and electronic engineering fields are reserved to IEC, the other fields being reserved to ISO, as sti pulated in ISO/IEC Directives Part 1 Annex B. Accordingly, the emergence of electrically propelled vehicles is the basis for two industries, road vehicle industry and electrical energy providers, in the past separated, to converge. This presents the need for new assessment of the standardization efforts between ISO and IEC. The purpose of this agreement is to create a framework of cooperation between ISO/TC 22 and IEC TCs/SCs using the existing modes of cooperation cited in Annex B clause B.4.2.2 to define the responsibilities of ISO and IEC for the standardization of electrotechnology for road vehicles. This agreement shall be fully applicable for all current and future technologies that are relevant for road vehicles.
The agreement aims to ensure an effective and professional development of standards for road vehicles and to avoid duplication in standardization. It shall support efficient work processes, because the availability of experts from all partners and resources fo r standardization are limited.
It is essential that standards for road vehicles can be used by their respective vehicle industries and that they are applicable in all international markets. Therefore ISO/TC 22, which has the standards development responsibility for road vehicles, and IEC, which has standards development responsibility for the electrotechnical area, are important collaboration partners in the development of standards related to electrically propelled vehicles .
For the specific case of an externally chargeable vehicle, when in the road position (not being connected to a source of external electrical energy) , standards shall be generally considered as being under the responsibility of ISO/TC 22. When connected to an external source of electrical energy, the standards that apply to electrical equipment used in similar circumstances are applicable (see annex A).
Scope of the agreement
International standardization of electrotechnology for road vehicles (i.e.: the related equipment including electrical and electronic systems and components) is the scope of this agreement.
In order to ensure the optimal use of expertise in both organizati ons, ISO and IEC, this agreement
defines the allocation of standardization work
between the related committees (ISO/TC 22 and
IEC committees) using the existing modes of cooperation cited in ISO/IEC Directives, Part 1 clause
This agreement is valid for all types of road vehicles and their equipment such as:
as defined in the relevant items of Article 1 of the convention on Road Traffic, Vienna in 1968 concluded under the auspices of the United Nations.
Standardization of electrotechnology for road vehicles
International standardization of electrotechnology for road vehicles concerns two fields of applications:
On-board equipment and performance of road vehicles,
Interface between externally chargeable vehicles and electricity supply infrastructure.
Annex A (informative) of this agreement lists ISO and IEC (TCs and SCs) standardization activities in the field of electrotechnology for road vehicles.
Annex B (informative) of this agreement lists current modes of cooperation.
Road vehicles – ISO/TC 22 Responsibility
ISO/TC 22 is responsible for all standardization issues concerning road vehicles and on–board systems.
These ISO/TC 22 standards shall normatively reference existing IEC standards for electrical and electronic components unless vehicle-specific conditions require otherwise. In such circumstances, ISO/TC 22 may request the relevant IEC committee to amend the IEC standard to make it suitable for application to vehicles or may develop its own standards , taking into account and referring to existing IEC standards as much as possible, and keeping the relevant IEC committee(s) informed.
Interface between externally chargeable road vehicles and electricity supply
Standards related to all interfaces between externally chargeable road vehicles and the electricity supply infrastructure shall be developed according to the ISO/IEC Directives Part 1, Annex B, if existing IEC or ISO standards cannot be used or modified. In case of dispute, mode 5 shall be applied if this is requested by one of the partners.
Coordination and avoidance of duplication
The chairmen of the involved ISO and IEC committees and subcommittees (see Annex A) shall ensure by all means that duplication in the development of International Standards is avoided and that work is appropriately coordinated.
ISO and IEC committees responsible for and involved in
standardization of electrotechnology for road vehicles1)
Within ISO/TC 22, the following SCs cover standardization of electrotechnology for road vehicles:
- ISO/TC 22/SC 01 – Ignition equipment
- ISO/TC 22/SC 03 – Electrical and electronic equipment
- ISO/TC 22/SC 08 – Lighting and signalling
- ISO/TC 22/SC 21 – Electrically propelled road vehicles
Within IEC, the following committees and subcommittees cover standardization of equipment and issues also used and related to road vehicles:
- IEC/TC 8 – Systems aspects for electrical energy supply
- IEC/TC 13 – Electrical energy measurement, tariff- and load control
- IEC/TC 21 – Secondary cells and batteries
- IEC/SC 21A - Secondary cells and batteries containing alkaline or other non -acid electrolytes

- IEC/SC 23H – Industrial plugs and socket-Outlets
- IEC/TC 34 – Lamps and related equipment
- IEC/SC 37A – Low-voltage Surge Protective Devices – Surge protection of electronic components will be
a very important consideration for plug in vehicles.
