22、2011 5 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 9-4: Endurance tests Test 9d: Durability of contact retention system and seals (maintenance, ageing) 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the
23、scope of IEC technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this standard is to detail a standard test method to assess the ability of a connector to withstand stresses caused by repeated extraction and insertion of contacts du
24、ring maintenance. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

27、Test 15d: Contact insertion, release and extraction force 3 Details of test equipment The test equipment shall consist of insertion and extraction tools as specified in the detail specification. 4 Preparation of the specimen The specimen shall consist of a component with all contacts installed and w
28、ired according to the detail specification. Loosen or remove any accessories to permit extraction and insertion of contacts. The accessories shall remain loose or be removed during the test.

29、n, for test specimens having fewer than 6 positions, all contacts shall be tested. For test specimens with more than 6 positions, 20 % of contact positions, but not less than 6 nor more than 10, shall be tested in each test specimen. For test specimens with more than 6 positions, the contacts tested
30、 shall be chosen at random but shall include at least one contact near the periphery and at least one near the centre of the insert or housing. For components having six or less contacts, all contacts shall be used for the tests. Unless otherwise specified, there shall be ten extraction and insertio
31、n cycles for each contact. 6 Initial measurements a) Contact retention in insert (IEC 60512-15-1, Test 15a). b) Contact insertion, release and extraction force (IEC 60512-15-4, Test 15d). 7 Final measurements a) Contact retention in insert (IEC 60512-15-1, Test 15a). b) Contact insertion, release an
32、d extraction force (IEC 60512-15-4, Test 15d). c) Visual examination for damage to wire, seals, etc. (IEC 60512-1-1, Test 1a). 8 Details to be specified When this test is required by the detail specification, the following details shall be given: a) design or type of insertion and extraction tools;
33、b) cable/wire to be used; c) preparation and mounting of the specimen; d) requirements for initial measurements; e) requirements for final measurements; f) any deviation from the standard test method. _ BS EN 60512-9-4:2011This page deliberately left blankBSI is the independent national body respons
