This International Standard defines technical aspects of experiments dealing with human or human surrogate testing and procedures for collecting and reporting biomechanical data. Recommended practices regarding measurements, instrumentation and reporting of results are outlined. These recommended practices are provided as guide for ease of interpretation and comparison of data among different organizations. This International Standard is limited to experiments involving indirect (inertial) impact and does not address direct impact with vehicle surfaces or the use of the airbag-type of active restraining device.
