The work of preparing International Standards is normally carried out through I
8、SO 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
9、closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards.
10、Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected da
11、ta of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to b
12、e reviewed until the data it provides are considered to be no longer valid or useful. 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.

ISO/TR 27957:2008(E) iv ISO 2008 All rights reservedIntroduction The temperature sensitivity of dummy components has long been recognized. All dummies used for testing in accordan
14、ce with current test procedures have prescribed temperature ranges for certification and testing. However, the procedure for verifying dummy temperature can vary from one testing facility to another. To improve the comparability of test data between laboratories, it is considered necessary to define
15、 a single practice for the measurement of dummy temperature. This Technical Report 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
16、 in accordance with the temperature corridor prescribed by the applied test procedure.

17、t 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. 2 Normative references The following reference
18、d documents are indispensable for the application 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 6487:2002/Amd 1:2008, Road vehicles Measurement techniques in impact
19、 tests Instrumentation Amendment 1 3 Equipment for temperature measurement and data logging The specifications for the equipment are included in ISO 6487:2002/Amd 1:2008. 4 Arrangement of temperature sensors in ATDs The locations represent the temperature sensitive parts of the dummies whose reading
20、s are consulted for the assessment of the risk of injury. The choice of the sensor locations should be feasible and crash-proof. The sensor locations are chosen in accordance with dummy manufacturer recommendations that are derived from tests conducted during the design process. If such recommendati
21、ons are not available, the sensor locations are chosen in accordance with other available temperature studies. The temperature studies with all details of the tests and all data should be available to the public, e.g. as ISO documents or published papers. The number and the exact locations of the te
22、mperature sensors for the different types of dummies are specified in Annexes A, B and C, each annex corresponding to a particular type of dummy or dummy family. ISO/TR 27957:2008(E) 2 ISO 2008 All rights reservedAnnex A (informative) Hybrid-III A.1 General This annex defines the sensor locations fo
23、r anthropomorphic test devices of the Hybrid-III family. The proposal of the number and the positions of the measuring points is based on studies conducted at DaimlerChrysler and Volkswagen. For further information, see References 1 and 2 in the Bibliography. A.2 Temperature sensor locations The Hyb
24、rid III 50th percentile should be equipped with one temperature sensor. The sensor should be attached to the spine box (front, left or right side). This location is only appropriate without restrictions if there is no heat generating source directly attached to the spine box, e.g. a data acquisition
25、 system. According to the studies (see References 1 and 2), the spine box sensor will represent the temperature of the ribs and the lumbar spine.
