15、ldwide 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
16、 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
17、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 Standar
18、d 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 7862 was prepared by Te

20、ed test procedure for the evaluation of restraint systems by simulation of frontal collisions 1 Scope This International Standard specifies a sled test procedure for the evaluation of restraint systems in road vehicles by the simulation of frontal collisions. Its main purposes are to improve test me
21、thods for evaluating restraint system efficacy and harmonize existing test methods especially to enable the comparison of results of tests carried out in different laboratories. It is applicable to restraint systems used within the structure of a passenger car as defined in ISO 3833. Deviations from
22、 its requirements are permitted, provided they have no significant effect on the results of the test. 2 Normative references The following referenced documents are indispensable for the application of this document.
