The work of preparing
13、 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 liais
14、on 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 te
15、chnical 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 dr

ISO 17373 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 10, Impact test procedures.
17、BS ISO 17373:2005vIntroduction Most head restraints of current vehicles are designed to minimize the risk of severe neck injuries such as bony fractures, luxations and ligament ruptures. However, so called “whiplash associated disorders” (WAD) of an AIS 1 injury severity degree still occur in consid
18、erable numbers. The majority of persons with such minor neck disorders soon recover without ongoing symptoms. Some victims, however, report long term impairment after even a “minor” event, also called “low-speed rear-end impact”. These injuries are difficult to diagnose even a careful medical examin
19、ation including CT scan and MRI often reveals no visible reason for a reported disorder and the complexities involved are often misunderstood. Therefore, legal and insurance related disputes are common. It has been shown in the relevant scientific literature that: whiplash associated disorders (WAD)
20、 predominantly occur in the struck vehicle in rear-end impacts; discussions about better seat and head restraint design in order to reduce WAD have been ongoing for a long time, given the complexity of the subject; many organizations interested in seat design (manufacturers of automobiles or seats,
21、universities, accident investigators, consumer test houses) have devised their own dynamic test procedures; to date, no standard test procedure is available that covers minor neck loading in typical “low-speed rear-end impacts”; accidentology analyses show that the majority of the neck disorders dis
22、cussed here occur during rear-end impacts which result in a velocity change of 10 km/h to 15 km/h for the struck vehicle. BS ISO 17373:2005blank1Road vehicles Sled test procedure for evaluating occupant head and neck interactions with seat/head restraint designs in low-speed rear-end impact 1 Scope
23、The sled test procedure described in this International Standard simulates low-speed rear-end impact resulting in a velocity change of the struck vehicle of 15 km/h. Its main purpose is the evaluation of the whiplash associated disorders due to seat occupant interactions with seat systems during the
24、 loading phase under standard conditions. Seat-belts shall be used unless it is proven that they do not affect the occupant response. The occupant protection potential of seat systems in other collision situations (e.g. higher velocity change/vehicle accelerations possibly resulting in large deforma
