ISO 3780:2009 道路車両—世界のメーカー識別子（WMI）コード | ページ 2

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 3780 was prepared by Technical Committee ISO/TC 22, Road vehicles.

This third edition cancels and replaces the second edition (ISO 3780:1983), which has been technically revised.

Introduction

The original world manufacturer identifier (WMI) code distribution per country was established over 25 years ago, and much has happened since the previous edition of this International Standard was published in 1983:

• some countries no longer exist;
• the automotive industries in some countries (e.g. China) have developed to such an extent that the countries concerned are rapidly using up their original WMI allocations;
• other countries that were originally allocated many WMIs, this allocation has gone unused due to the lack of a major automotive industry in the country concerned.

In order to address the issue before a critical point is reached, the international agency for the maintenance of WMI codes, the Society of Automotive Engineers (SAE), together with the SAE VIN/WMI committee, has updated and adjusted the WMI code matrix. Annex A contains the amended global WMI code distribution.

In the course of revising this International Standard, the following significant modifications have also been made with respect to the previous edition:

• the separate clauses “Scope” and “Field of application” have been combined into a single Clause 1, and the subsequent clauses have been renumbered accordingly;
• the terms and definitions in Clause 3 have been made more comprehensive and revised in accordance with the state of the art;
• the content of 4.3 has been amended in order to reduce the risk of different interpretations.

1 Scope

This International Standard specifies the content and structure of an identifier in order to establish, on a world-wide basis, the identification of road vehicle manufacturers. The world manufacturer identifier (WMI) constitutes the first section of the vehicle identification number (VIN) described in ISO 3779.

This International Standard applies to motor vehicles, towed vehicles, motorcycles and mopeds as defined in ISO 3833.
