ISO 13232-2:2005

Overview

ISO 13232-2:2005 - part of the ISO 13232 series - defines how to derive representative motorcycle impact conditions from real accident data for research into rider crash protective devices. It specifies minimum requirements for collecting and analysing motorcycle/car collision data to produce a standardized subset of accident configurations and corresponding impact conditions used in feasibility studies and paired full‑scale impact tests (motorcycle with and without the protective device). Note: ISO 13232-2 is intended for research purposes and does not apply to regulatory or legislative testing.

Key topics and technical requirements

• Impact variables required to characterise an accident:
  • Relative heading angle (RHA)
  • Opposing vehicle (OV) impact speed
  • Motorcycle (MC) impact speed
  • OV contact point and MC contact point
• Accident data sampling: each regional database used for frequency analysis must contain at least 200 motorcycle accidents, uniformly sampled and based on in‑depth investigations (on‑site measurements and reconstructions).
• Standardized accident configurations: Annex B provides the standardized configurations and occurrence frequencies derived from the combined analyzed databases (example sources in Annex C include Los Angeles and Hannover datasets).
• Analysis methods: procedures to use accident data to determine (a) frequency of occurrence of impact configurations and (b) frequency of injury by body region and injury type (see Annex D for example injury frequency outputs).
• Documentation and reporting: requirements for consistent accident reporting formats and the variables to capture (Annex A contains the motorcycle accident report template).

Practical applications

• Establishing realistic impact conditions for laboratory and full‑scale tests used in research on rider protective systems (airbags, frame structures, add-on protective devices).
• Defining input scenarios for computer simulations and human‑surrogate (dummy) testing that reflect real-world crash geometries and speeds.
• Supporting failure mode and effects analyses (FMEA) and comparative risk/benefit assessments of proposed protective devices.
• Producing reproducible datasets and test conditions that improve comparability across research studies and manufacturers.

Who uses this standard

• Motorcycle safety researchers and academic groups
• Motorcycle and component manufacturers developing crash protective devices
• Automotive and motorcycle crash test laboratories
• Simulation engineers performing impact modelling
• Insurers and road‑safety analysts conducting research (with awareness the standard is not for legislative testing)
