16、 testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to assess the effectiveness of the means by which an oversize male contact, or ot
17、her similar object, is prevented from entering the equivalent female contact. NOTE Although this test is particularly applicable to cylindrical contacts, the use for contacts with other geometries is not excluded. In which case, the detail specification should contain sufficient detail, given under
18、5.e), to enable the test to be done. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments
19、) applies. IEC 60512-1-1, Connectors for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector with its terminations, and may be wired if so specified in the detail sp
20、ecification. Any preconditioning given in the component detail specification shall be applied. If lubricant is required by the detail specification, this shall be applied in the manner so specified. 3.2 Equipment A test gauge, as specified in the detail specification, shall be provided. 3.3 Pre-cond
21、itioning Any pre-conditioning of the samples required by the applicable detail specification shall be applied. 3.4 Mounting If mounting of the specimen is necessary, it shall be as specified in the detail specification. 3 BS EN 60512-16-2:20084 Test method 4.1 Procedure Attempts shall be made to ent
22、er the specified test gauge into the connector under test. If a maximum force to achieve this is given in detail specification, this shall not be exceeded. If no such force is specified, the maximum force deemed appropriate by the testing laboratory shall be applied. The value of this force shall be
23、 recorded. 4.2 Measurements and requirements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects, which would impair the validity of the test. 4.2.2 During testing If it is possible to cause the test gauge to enter the connector under te
24、st, such force shall be measured. NOTE It is recommended that electrical contact between the test probe and the contact under test be one criterion of entry. 4.2.3 After testing Visual examination according to IEC 60512-1-1 shall be carried out. Details shall be specified. 5 Details to be specified
25、When this test is required by a detail specification, the following shall be given therein: a) whether preconditioning is required; b) wiring of the specimen; c) whether special mounting of the specimen is required; d) maximum force to be applied may be specified; e) if the contact is not cylindrica
26、l, sufficient details of equipment procedure, and measurements, for the test to be done; f) any deviation from the standard test method. _ 4 BS EN 60512-16-2:2008Annex ZA(normative) Normative references to international publications with their corresponding European publications The following refere
