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 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 16750-2 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 16750-2:2006), which has been technically revised. ISO 16750 consists of the following parts, under the general title Road vehicles Environmental conditions and testing for electrical and electronic equipment: Part 1: General Part 2: Electrical loads Part 3: Mechanical loads Part 4: Climatic loads Part 5: Chemical loads 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m BS ISO 16750-2:2010 INTERNATIONAL STANDARD ISO 16750-2:2010(E) ISO 2010 All rights reserved 1 Road vehicles Environmental conditions and testing for electrical and electronic equipment Part 2: Electrical loads 1 Scope This part of ISO 16750 applies to electric and electronic systems/components for road vehicles. This part of ISO 16750 describes the potential environmental stresses and specifies tests and requirements recommended for the specific mounting location on/in the road vehicle. This part of ISO 16750 describes the electrical loads. Electromagnetic compatibility (EMC) is not covered by this part of ISO 16750. Electrical loads are independent from the mounting location, but can vary due to the electrical resistance in the vehicle wiring harness and connection system. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
