The work of preparing International Standards is normally carried out through ISO technicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeer InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. 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. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard ("state of the art", for example), it may decide by a informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.

These curves, summarized in this Technical Report, can be used by regulatory authorities as well as car manufacturers to set occupant protection levels based on the injury risks they believe are acceptable for the f
