1、 EIA STANDARD TP-75A Lightning Strike Test Procedure for Electrical Connectors EIA-364-75A (Revision of EIA-364-75) January 2009 ANSI/EIA-364-75A-2009(R2015) Approved: January 13, 2009 Reaffirmed: March 24, 2015 EIA-364-75ANOTICE EIA Engineering Standards and Publications are designed to serve the p

2、ublic 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 an

3、d Publications 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

4、 the 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 obligat

5、ion whatever to parties adopting the Standard or Publication. This EIA standard is considered to have International Standardization implication, but the International Electrotechnical Commission activity has not progresses to the point where a valid comparison between the EIA Standard and the IEC do

6、cument can be made. 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 applicability of regula

7、tory limitations before its use. (From Standards Proposal No. 5175, formulated under the cognizance of the CE-2.0 Committee on EIA National Connector and Socket Standards, and reaffirmed per Standards Proposal No. 5346.06).

9、imulated lightning current pulse exposure. Test currents are provided in table 1 and table 2. The simulated current pulse shall be applied between the plug accessory braid and the receptacle mounting panel. Upon completion of the pulse application, perform shell-to-shell conductance test. When the e

10、lectrical measurements have been completed, the specimen shall be visually inspected in both the mated and unmated condition for evidence of damage from the simulated lightning current. Remate the plug and receptacle following the inspection and repeat the shell-to-shell conductance test. EIA-364-75
