ISO 17949:2013 PDF

Overview

ISO 17949:2013 specifies standardized impact test procedures for motor vehicles, focusing on seating and positioning of anthropomorphic test devices. This standard details the recommended methodology for placing the WorldSID 50th percentile male side-impact dummy (WS50) in front outboard seats during side-impact testing. Developed by ISO’s Technical Committee ISO/TC 22/SC 10, this standard ensures repeatability and consistency in side-impact safety assessments and supports global harmonization of vehicle occupant protection evaluation.

Key Topics

• Scope and Application Defines conditions and requirements for positioning the WS50 dummy in front outboard seats of vehicles, helping assess side-impact protection performance consistently.

• Vehicle Seat Preparation

  • Adjust seat components to manufacturer’s nominal positions or lowest/retracted settings (lumbar support, cushion length, leg support, pedals, steering wheel).
  • Set head restraints and seat belt anchorages appropriate for a 50th percentile adult male.

• Seat Reference Points and Markings

  • Mark rear seat cushion reference points and longitudinal centerline for accurate dummy placement.
  • Define cushion pitch angles for proper seat inclination during testing.

• Test Seat Placement Procedure

  • Steps for adjusting seat forward-backward and vertical positions to a defined test posture, including midpoint and slight rearward offset for placement accuracy.

• H-point Determination Using SAE J 826 Manikin

  • Positioning of the H-point that represents the occupant’s hip joint location, adjusted specifically for the WS50 dummy.

• WS50 Dummy Placement

  • Techniques for seating the dummy accurately, including pelvis and torso positioning, foot and leg placement for driver and passenger sides.
  • Adjustments of dummy rib angle and head level to meet test specifications.
  • Arm positioning in detent (45° from coronal plane) for realistic posture.

Applications

• Vehicle Side-Impact Testing Ensures reproducible dummy positioning to evaluate side-impact protection devices such as side airbags, door intrusion barriers, and seatbelt systems.

• Automotive Safety Research and Development Supports vehicle manufacturers and safety engineers in optimizing occupant protection design through reliable anthropomorphic test device placement.

• Regulatory Compliance and Certification Assists testing agencies and certification bodies in verifying adherence to international side-impact safety requirements using a harmonized dummy placement method.

• Crash Test Laboratories Standardizes procedures enabling consistent application of side-impact test protocols across different testing facilities worldwide.

Summary

ISO 17949:2013 provides comprehensive, internationally harmonized instructions for positioning the WorldSID 50th percentile male side-impact dummy in front outboard seating positions of road vehicles during side-impact tests. By standardizing seat adjustments, reference point markings, and dummy placement, this standard enhances consistency and reliability in crash testing outcomes. Its integration with the ISO 15830 dummy specifications and SAE J 826 H-point measurement makes it a critical reference for automotive safety development, regulation, and testing laboratories focused on occupant side-impact protection.
