ISO/TC 22/SC 36/WG 3 - Instrumentation

This document defines the measurement coordinate systems and presents the protocol to determine the sensor offsets to the chosen coordinate system. Finally, the method is presented how to process the sensor spherical coordinate system data to calculate the position of a dummy feature in three-dimensional space in the defined local orthogonal coordinate system.

This document establishes a procedure to calibrate 1D displacement transducers with nearly linear transfer functions. This procedure is tailored to the needs of sensors used in crash tests. The calibration is carried out with the sensor disassembled from the dummy or test system. The procedure is valid for sensors with analogue as well as digital output.

This document establishes an adequate procedure to determine crosstalk values in order to improve comparability of measurement results between testing laboratories and to enable a load cell performance rating in accordance to the crosstalk specification for transducers in vehicle crash testing given in ISO 6487, SAE-J211-1 and SAE J2570.

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.

This document presents a simple means for the exchange of multimedia data on impact tests between different laboratories. A format has been developed which defines a directory structure and the exchange information as ASCII files. Related electronic documents are available on the ISO website.

This document establishes a procedure to calibrate IR-TRACC displacement transducers. Like all other sensors used on dummies, calibration is required. The calibration is carried out with the sensor disassembled from the dummy. The procedure is valid for sensors with analogue as well as digital output.

This document defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from images to analyse impact test results. The objective of this document is to facilitate comparison between results obtained by different laboratories by specifying minimum quality criteria. Annexes A, B, C and D present a method of measuring several indices like quality parameters of sub processes of the optical data channel, using a calibration target, reference distances and analysis systems.

ISO 6487:2015 gives requirements and recommendations for measurement techniques involving the instrumentation used in impact tests carried out on road vehicles. Its requirements are aimed at facilitating comparisons between results obtained by different testing laboratories, while its recommendations will assist such laboratories in meeting those requirements. It is applicable to instrumentation including that used in the impact testing of vehicle subassemblies. It does not include optical methods which are the subject of ISO 8721.

ISO/TS 17242:2014 provides a procedure to calibrate seat belt force transducers with loading capacities up to 25 kN and consistent test specifications and sequences in order to improve comparability of measurement results between testing laboratories.

ISO/TS 22240:2008 presents an enhanced data exchange and data storage format for all data relevant for vehicle safety tests. The underlying data model is based on ASAM ODS, and the corresponding exchange format is XML.

This Technical Report gives methods to determine the instant of head contact and the duration of this contact during impact tests. The determination of head engagement and disengagement times are used in the calculation of the contact head injury criteria (HIC).

Specifies the accuracy of measurement of the impact velocity. Describes in the annex some typical methods suitable for the measurement. These methods are intended to facilitate the comparison of data obtained in similar tests by different laboratories. Other methods may be used provided they meet the requirements of 2.1 and 2.2.

ISO/TS 13499:2014 presents a simple means for the exchange of multimedia data on impact tests between different laboratories. A format has been developed which defines a directory structure and the exchange information as ASCII files. Related electronic documents are available on the ISO website.

ISO 8721:2010 defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from images to analyse impact test results. The objective of ISO 8721:2010 is to facilitate comparison between results obtained by different laboratories by specifying minimum quality criteria.

ISO 27957:2008 defines the number and the arrangement of temperature measuring points for anthropomorphic test devices (ATDs), in order to ensure that the temperature of the ATD is in accordance with the temperature corridor prescribed by the applied test procedure.
