Overview

ISO/TR 12349-2:2015 provides ISO's recommended infant and child crash test dummies and related instrumentation for evaluating child restraint systems in frontal impacts and out-of-position (OOP) interactions with frontal or side airbags. The Technical Report consolidates expert review of widely available dummies based on biofidelity, repeatability, durability and instrumentation capability. It represents practical guidance for test laboratories, manufacturers and regulatory or consumer test programs.

Key Topics

  • Recommended dummies for frontal impact tests:

    • CRABI 12-month old
    • Hybrid III 3-year old (for forward-facing child restraints only)
    • Q3
  • Recommended dummies for out-of-position (OOP) airbag tests:

    • CRABI 12-month old
    • Hybrid III 3-year old
    • Hybrid III 6-year old
  • Dummy instrumentation guidance:

    • Instrumentation recommendations align with instrumentation required by ISO test procedures and include required and some optional sensor sets.
    • For the CRABI 12-month old, recommended instrumentation covers head, neck (head/C1 and C7/torso loads and moments), thorax, lumbar and pelvis accelerations and loads.
    • For Hybrid III and Q3 child dummies, recommended instrumentation includes head linear accelerations, neck loads and moments, spine and sternum accelerations, sternum deflection, pelvis accelerations and ASIS/acetabulum loads; Hybrid III 6-year also includes lower extremity femur loads and moments.
  • Limitations noted in the report:

    • No consensus was reached to recommend infant or child dummies specifically for side impact tests at the time of publication.
    • Dummies protected by intellectual property were not considered in the review.

Applications

ISO/TR 12349-2:2015 supports practical use cases and improves consistency across testing programs:

  • Manufacturers can select appropriate child dummies and instrumentation when validating restraint systems and seats.
  • Test laboratories and certification bodies can align test setups for frontal and OOP airbag evaluations with ISO recommendations.
  • Regulatory agencies and consumer test organizations can reference the Technical Report to inform test protocols and improve comparability of results.

Benefits include enhanced repeatability and comparability of child restraint evaluations, clearer instrumentation requirements, and improved assessment of OOP airbag interactions.

Related Standards

  • ISO/TR 14645 - Test procedures for evaluating child restraint interactions with deploying airbags
  • ISO/TR 10982 - Test procedures for evaluating out-of-position occupant interactions with deploying airbags
  • ISO/TR 14933 - Test procedures for evaluating occupant interactions with deploying side impact airbags

This Technical Report is part of the ISO series on dummies for restraint system testing and provides targeted guidance for selecting child crash test dummies and sensor suites used in frontal impact and OOP airbag scenarios.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
