19、 11p: Flowing single gas corrosion test 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing of connectors for electronic equipment. This test may also be used for similar components when specified in a detail specification. The object of this tes

20、t is to define a standard test method, Test 11p, to assess the effects of controlled corrosion in industrial atmospheres, in a specified concentration of polluted gas(es). 2 Normative references The following referenced documents are indispensable for the application of this document.

When required by the detail specification, the specimen shall be operated the number of times specified prior to the test. For each test carried out, the detail specification shall

25、specify the condition and the severity of the component, for example, operated or non-operated, mated or unmated. NOTE In the case of several specimens, it is recommended to divide the specimens into two groups with different conditions. Page3 EN605121114:20034 Method 4.1 Procedure Test 11p shall be

26、 carried out in accordance with IEC 60068-2-42, Test Kc: Sulphur dioxide test for contacts and connections; IEC 60068-2-43, Test Kd: Hydrogen sulphide test for contacts and connections; IEC 60068-2-49, Guidance to Test Kc: Sulphur dioxide test for contacts and connections. 4.2 Severity of the test T

27、he test severity, to be given in the relevant specification, is defined by type and concentration of polluting gas; temperature; relative humidity; duration of exposure.

31、tion; c) pitting of exposed metal surfaces. Page4 EN605121114:20035 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) method of preparation and mounting of the specimens; b) conditioning of the specimens prior to the test (if

32、 required); c) severity, type, concentration and temperature of polluting gas; d) initial measurements; e) requirements; f) duration of exposure; g) final measurements; h) any deviation from the standard test method. _ Page5 EN605121114:2003 Annex ZA (normative) Normative references to international
