rights reserved 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, Part 3. 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 part of ISO 8092 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 8092-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This third edition cancels and replaces the second edition (ISO 8092-2:1996), which has been technically revised. ISO 8092 consists of the following parts, under the general title Road vehicles — Connections for on-board electrical wiring harnesses: — Part 1: Tabs for single-pole connections — Dimensions and specific requirements — Part 2: Definitions, test methods and general performance requirements — Part 3: Tabs for multi-pole connections — Dimensions and specific requirements — Part 4: Pins for single- and multi-pole connections — Dimensions and specific requirements Annexes A and B of this part of ISO 8092 are for information only. INTERNATIONAL STANDARD ISO 8092-2:2000(E) © ISO 2000 – All rights reserved 1 Road vehicles — Connections for on-board electrical wiring harnesses — Part 2: Definitions, test methods and general performance requirements 1 Scope This part of ISO 8092 defines terms and specifies test methods and general performance requirements for single- and multi-pole connections used with on-board electrical wiring harnesses in road vehicles. This part of ISO 8092 is applicable to connectors designed to be disconnected after mounting in the vehicle for repair and maintenance only. It does not cover one-part connections, i.e. where one part of the connection has direct contact with the pattern of the printed circuit board. This part of ISO 8092 is not applicable to the internal connections of electronic devices. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 8092. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 8092 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

Contacts with a locking device shall be tested with adequate counterparts to permit locking. Cables shall be in conformance with ISO 6722-3 or ISO 6722-4, and the cable or cables used shall be noted in the test report. Cable attachment shall be performed in accordance with the contact manufacturer’s recommendations. Care shall be taken so that test samples do not influence each other (e.g. in a heat chamber). Each connector shall have the full complement of contacts fitted, unless otherwise specified by the test method. Measurements shall be taken on a minimum of four contacts per connector, unless otherwise specified in the test method. For 1-, 2- and 3-pole connectors, all contacts shall be measured. During the entire test sequence, lubrication or other means of attaining better test results shall not be added to the test surface. However, production-related remains of lubricants on the contacts are permitted. 4.1.3 Multiple-position connections Connectors or contacts that allow connections for multiple positions shall meet the requirements of this part of ISO 8092 in all intended positions. 4.1.4 Test sequences The test sequence for each sample group shall be in accordance with Table 1 (sequences are indicated by Xs, ordered from top to bottom).
