The object of this standard is to detail a standard test method to assess the ability of a connector to withstand elevated temperatures with electrical loading. 2 Normative references The following documents,

28、ecimen shall be suitably fitted with temperature-sensing device(s) with dimensions as laid down in the detail specification, and be wired and mounted according to the detail specification. NOTE 1 Heat transfer by a measuring probe will influence the measurement. Care should be taken to limit this in

29、fluence, e.g. by using a non-intrusive measuring method. BS EN 60512-9-2:2012 6 60512-9-2 IEC:2011 NOTE 2 Attention is drawn to the fact that reproducibility is frequently improved by arranging the wiring horizontally. Equipment 3.2A suitable climatic chamber. Influence of the air circulation to the

30、 specimen shall be avoided. 4 Test method The specimen shall be subjected to a temperature endurance test with electrical load in accordance with the requirements of the detail specification. Initially (see note) and again at the end of the test, the insulation resistance at high temperature shall b

31、e measured according to IEC 60512-3-1, test 3a and shall be not less than the value specified by the detail specification. NOTE Due to the fact that specimen may be wired in series, an insulation resistance measurement after e.g. 10 h of exposure can be unpractical. In cases where such a measurement

32、 is possible, early failures will be detected, so that time-consuming testing can be avoided. The prepared specimen shall be placed in a chamber, the temperature of which shall be maintained at 70 % 5 % of the specified maximum operating temperature of the specimen under test. Current shall be appli

33、ed to the specimen and slowly increased until the specified maximum operating temperature (= ambient + temperature-rise due to current) is approached. There shall be no further increase of current before thermal stability is attained. In no case during the adjustment shall the specified maximum oper

34、ating temperature or the specified current of the specimen be exceeded. When the maximum operating temperature is reached, the current required to achieve this shall be maintained throughout the test. If the temperature rise due to the specified maximum current through the specimen does not cause it

35、 to reach its specified maximum operating temperature, the chamber temperature shall be increased until the specified maximum operating temperature of the specimen is reached. The test shall be carried out at the specified maximum operating temperature and the duration of the test shall be as specif

36、ied in the detail specification. Preferred durations are 250 h, 500 h, 1 000 h and 2 000 h. At the end of the exposure period, the specimen shall be allowed to cool under standard atmospheric conditions for a time as stated in the detail specification. If the maximum operating temperature of the spe

37、cimen is exceeded by 5 % under normal test conditions, the test shall be abandoned and the test shall be regarded as “failed“. 5 Final measurements a) Contact resistance (IEC 60512-2-1, test 2a, or IEC 60512-2-2, test 2b). b) Housing (shell) electrical continuity (IEC 60512-2-6, test 2f), where appl

38、icable. c) Insulation resistance (IEC 60512-3-1, test 3a). d) Voltage proof (IEC 60512-4-1, test 4a). e) Visual examination (IEC 60512-1-1, test 1a). f) Operational tests as required in the detail specification. NOTE If applicable, the detail specification may require a sealing test from the IEC 605

39、12-14 series or an ingress protection test according IEC 60529. BS EN 60512-9-2:201260512-9-2 IEC:2011 7 6 Details to be specified When this test is required by the detail specification, the following details shall be given: a) maximum operating temperature; b) duration; c) maximum load current; d)

40、insulation resistance (in hot condition); e) recovery time prior to final measurements; f) requirements for final measurements; g) any deviation from the standard test method. _ BS EN 60512-9-2:2012This page deliberately left blankThis page deliberately left blankBSI is the independent national body
