This International Standard specifies a report form for the collection of data in accidents with children under the age of 13 in motor vehicles. The aim of this standardized form is to provide a simple format for reporting road accidents where children are involved. Severe accidents where children have been sitting in a child restraint system are rare. Therefore, the format has been designed in a way that it should be possible to use in all countries, although the design of child restraint systems varies, in order to simplify the exchange of data. The coding used in this form is based on ISO 6813, ISO 12353-1, AIS manual from AAAM (Association for the advancement of automotive medicine) and SAE J 224 (CDC-coding).
