1、 EIA STANDARD TP-32G Thermal Shock (Temperature Cycling) Test Procedure for Electrical Connectors and Sockets EIA-364-32G (Revision of EIA-364-32F) August 2014 ANSI/EIA-364-32G-2014 Approved: August 15, 2014 EIA-364-32G NOTICE EIA Engineering Standards and Publications are designed to serve the publ

2、ic interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and P

3、ublications shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than ECIA members, whether th

4、e standard is to be used either domestically or internationally. Standards and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any patent owner, nor does it assume any obligation

5、 whatever to parties adopting the Standard or Publication. This standard is based upon the major technical content of International Electrotechnical Commission standard 60512-11-4 (was IEC 512-6, test 11d), Rapid Change of Temperature, 2002-02, first edition. There are known differences between this

6、 standard and the IEC standard. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicabili

7、ty of regulatory limitations before its use. (From Standards Proposal No. 5332, formulated under the cognizance of the CE-2.0 Committee on EIA National Connector and Sockets Standards.)

8、edure 4.1 Mounting The specimens shall be placed in such a position with respect to the air stream that there is substantially no obstruction to the flow of air across and around each specimen. When special mounting is required, it shall be specified. 4.2 Initial measurements Specified measurements

9、shall be made prior to the first cycle, and they shall be made at standard ambient conditions. 4.3 Specimen mass determination The mass of the specimen in table 2 is the total mass of the mated assembly, wire and any fixture attached to the specimen. Table 2 - Exposure time at temperature extremes M

10、ass of specimen Minimum time for steps 1 and 3,hours 28 g (1 oz) and below ; or (when specified) 28 g (1 oz) to 136 g (0.3 lb) inclusive 136 g (0.3 lb) to 1.36 kg (3 lb) inclusive 1 1.36 kg (3 lb) to 13.6 kg (30 lb) inclusive 2 13.6 kg (30 lb) to 136 kg (300 lb) inclusive 4 NOTE When step one consis

11、ts of cryogenic immersion of the specimen in liquid nitrogen, as specified in table 4, exposure time shall be as specified in table 2 or the amount of time necessary to obtain thermal stability of the test specimen. 4.4 Cycling 4.4.1 Subject test specimens to the test method, test condition and test

12、 duration as specified in the referencing document. 4.4.2 When a test is not specified in the referencing document, method A, test condition I, test duration A, shall be used as the default. 4.4.3 The first five cycles shall be run continuously. After five cycles, the test may be interrupted after t

13、he completion of any full cycle and the specimens allowed to return to room ambient temperature before testing is resumed. One cycle consists of steps 1 through 4 of the applicable test condition. The test may be started in either the hot or cold temperature. At the conclusion of the test the specim

14、ens may be removed from the chamber or the specimens may remain in the chamber while the chamber returns to room ambient conditions. 4.4.4 Specimens shall not be subjected to forced circulating air while being transferred from one chamber to another or to a dewar of liquid nitrogen.
