16、act spring holding force 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing electomechanical components within the scope of technical committee 48. This test may also be used for similar devices when specified in a detail specification. The obje

17、ct of this part of IEC 60512 is to detail a standard test method to determine the holding capacity of grounding contact springs by means of gauges. 2 Normative references The following referenced documents are indispensable for the application of this document.

If lubricant is specified for use with the contact

20、system, it shall be applied in the manner specified in the component detail specification. Any preconditioning given in the component detail specification shall be applied. 3.2 Equipment Set(s) of gauges as specified in the component detail specification, shall be provided. 3.3 Mounting If mounting

21、of the specimen is appropriate, it shall be as specified in the component detail specification. 3 BS EN 60512-16-9:20084 Test methods 4.1 Method A Single contact gauges 4.1.1 Female contact springs Each contact to be tested shall have the maximum size gauge specified, engaged and separated three tim

After which, the minimum size retention force gauge specified shall be inserted. 4.1.2 Male contact springs Each contact to be tested shall have the minimum size gauge specified, engaged and separated three times. After which, the contact shall be inserted into the maximum size retention force g

23、auge specified. 4.2 Method B Multiple contact gauges As Method A, except that contacts shall be tested in specified groups using gauges having multiple contact engaging elements. After which appropriate individual maximum or minimum gauges shall be used. 4.3 Measurements and requirements 4.3.1 Befor

24、e 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. 4.3.2 During testing Contacts shall support the weight of the individual contact retention force gauge in a vertically downward direction. 4.3.3 After

25、 testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects that would impair the normal functioning of the component. Special attention shall be given to the resilient features of the specimen. 5 Details to be specified When this test is required by a deta

26、il specification, the following details shall be specified: a) whether preconditioning is required; b) nature and means of application of any lubricant to be applied; c) whether the specimen is to be wired, and if so, details of this; d) whether special mounting of the specimen is required; e) detai

27、ls of gauges to be used, including surface roughness, according to ISO 1302; f) number of specimens to be tested; g) any deviation from the standard test method. _ 4 BS EN 60512-16-9:2008Annex ZA(normative) Normative references to international publications with their corresponding European publicat
