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

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 36,

Safety and impact testing.

This second edition cancels and replaces the first edition (ISO/TR 27957:2008), which has been

technically revised.
The main changes compared to the previous edition are as follows:

— the addition of Annexes D to G to include temperature positions for multiple devices.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

This document proposes the number and the arrangement of the temperature measuring points in

anthropomorphic test devices (ATDs). The proposal is based on several studies and is intended to

ensure that the temperature of the ATD is in accordance with the temperature corridor prescribed by

the applied test procedure.

The temperature sensitivity of ATD components has long been recognized. All ATDs used for testing

in accordance with current test procedures have prescribed temperature ranges for certification and

testing. However, the procedure for verifying ATD temperature can vary from one testing facility to

another. To improve the comparability of test data between laboratories, it is considered necessary to

define a single practice for the measurement of ATD temperature.

temperature sensor locations
1 Scope

This document defines the number and the arrangement of temperature measuring points for

anthropomorphic test devices in order to ensure that the temperature of the ATD is in accordance with

the temperature corridor prescribed by the applied test procedure.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 6487, Road vehicles — Measurement techniques in impact tests — Instrumentation

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 6487 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
4 Equipment for temperature measurement and data logging

The temperature measurement sensor is mounted with no modifications of dummy structure and

performance. The temperature measurement sensor is thermally coupled to the surface according to

the figures
5 Arrangement of temperature sensors in anthropomorphic test devices

The locations represent the temperature sensitive parts of the dummies whose readings are consulted

for the assessment of the risk of injury. The choice of the sensor locations is feasible and crash-proof.

The sensor locations are chosen in accordance with anthropomorphic test device manufacturer

recommendations that are derived from tests conducted during the design process. When such

recommendations are not available, the sensor locations are chosen in accordance with other available

temperature studies.

The number and the exact locations of the temperature sensors for the different types of

anthropomorphic test devices are indicated in Annexes A to G, each annex corresponding to a particular

type of anthropomorphic test device or anthropomorphic test device family.

Annex A
(informative)
Hybrid-III
A.1 General

This annex defines the sensor locations for anthropomorphic test devices of the Hybrid-III family.

A.2 Temperature sensor locations

The Hybrid III family is equipped with one temperature sensor. The sensor is attached to the inner

surface of the 3 rib (left or right side), except for the HIII 3 years old (YO) child, where the sensor is

attached to the inner side of 2 (central) rib of the anthropomorphic test device. The sensor is mounted

on the damping material.

Different options for the position of the temperature sensor are marked with different labels.

The tolerance of this position is a circle with a 25 mm radius.

Figures A.1 to A.10 show the measuring points for anthropomorphic test devices of the Hybrid-III family.
