The object of this test is to detail a standard method to as
24、ses the performance of mated contact pairs of connectors with an electrical overload current flowing through them for a limited period of time, in the order of 1 ms to 1 s. NOTEPractice shows that for limited periods of time contacts can conduct a multiple of the maximum permissible current without
25、damage to the contact area. Transient surge currents, ranging from 1 ms to 1 s in time, may flow through connectors before protective circuits respond, for example, when a fault occurs in equipment or in a system. 2 Normative reference The following normative document contains provisions which, thro
26、ugh reference in this text, constitute provisions of this section of IEC 512-10. At the time of publication, the edition indicated was valid. All normative documents are subject to revision, and parties to agreements based on this section of IEC 512-10 are encouraged to investigate the possibility o
27、f applying the most recent edition of the normative document indicated below. Members of IEC and ISO maintain registers of currently valid normative documents. IEC 512, Electromechanical components for electronic equipment; basic testing procedures and measuring methods. 3 Preparation of specimens T
28、he connectors shall be wired with the maximum wire size for the contacts and, unless otherwise specified in the detail specification, the shortest possible wire lengths compatible with the contact arrangement. Contacts of the same size in a connector set shall be wired in series. The connectors shal
29、l be mated. 4 Test method 4.1 Initial measurements (if applicable) The initial measurements shall be made as prescribed by the detail specification. 4.2 Conditioning A current of five times the current-carrying capacity given in the detail specification shall be applied to the circuits established a
30、s described in clause 3 for each contact size and for the duration specified by the detail specification. The other circuits shall not be energized. Recovery under test conditions is required between two consecutive tests. This conditioning shall be repeated for a total of eight cycles for each circ
31、uit. NOTETemporary emission of smoke due to thermal degradation of surface contaminants is permissible. This should not be considered as a defect if the performance is not affected. 4.3 Final measurements and requirements (if applicable) The specimen shall be subjected to the following test sequence
32、 (IEC 512 series) and shall meet the requirements of the detail specification: a) contact resistance at specified current (test 2b); b) measurement of insulation resistance (test 3a); c) voltage proof test (test 4a); d) unmating forces (as per tests 13a and 13b); e) visual examination (test 1a). 5 D
33、etails to be specified When this test is required by the detail specification, the following details shall be specified: a) number of contact sets to be tested; b) type and size of wire used; c) initial measurements (if applicable); d) current and voltage to be applied to each circuit; e) duration o
34、f current application; f) final measurements and requirements (if applicable).
