19、atic tests Test 11j: Cold 1 General 1.1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing electromechanical components within the scope of IEC technical committee 48. This test may also be used for similar devices when specified in a detail speci

20、fication. The object of this test is to define a standard test method to assess the ability of components to be stored and/or to function in a specified manner under specified conditions of cold. 1.2 Normative references The following referenced documents are indispensable for the application of thi

21、s document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

27、uired; Test Ab: Cold for non-heat-dissipating specimens with gradual change of temperature when measurements during the test are required; using the degree of severity specified in the detail specification. 3.2 Initial measurements Initial measurements shall be carried out as specified by the detail

28、 specification. 3.3 Measurements during the test When required by the detail specification, the measurements shall be carried out at the end of the test, while the specimen is still at the specified low temperature. 3.4 Final measurements The specimens shall be subjected to the following tests, unle

29、ss otherwise specified in the detail specification and shall meet the requirements specified in the detail specification. Contact resistance Millivolt level method: IEC 60512-2-1, Test 2a; Insertion and withdrawal forces: IEC 60512-7, Test 13b; Visual examination: IEC 60512-1-1, Test 1a; Page4 EN605
