Foreword

This section GB/T 2423 Part 20, part of the GB/T 2423 standard, see informative Annex NA.

This section drafted in accordance with GB/T 1.1-2009 given rules.

2003 (2nd edition) "Environmental testing - Part 2-43.. Experimental tests of this translation method using equivalent IEC 60068-2-43 use Kd. contacts and connections of hydrogen sulfide test. " this part of IEC 60068-2-43:2003 (2nd edition), compared mainly to do the following editorial changes.

--- This part of the name changed to "Environmental Testing Part 2. Test methods - Test Kd. contacts and connections of hydrogen sulfide test";

--- IEC 60068-2-43:2003 (2nd edition) Chapter 1 and the references mentioned IEC 60355. 1971, due to the IEC 60355.

1971 was repealed, in order to make better use of the standard, this section refers to GB/T 2424.10-2012;

--- Increase the informative appendix NA.

1 Scope and purpose

The test.

--- Used for the evaluation of contacts and connections of silver and silver alloy provides an accelerated test method for color;

--- Particularly suitable for comparison test;

--- Not as a general corrosion test in that it can be unpredictable contacts and connections in industrial atmospheric corrosion behavior.

Note. In view of the information obtained is limited accelerated corrosion test, should pay special attention to this test guide GB/T 2424.12 is given. And with reference to GB/T 2424.10.

The purpose of this test is.

a) to determine the effects of exposure to hydrogen sulphide-containing atmosphere point to the following materials and contact characteristics of the connector.

--- Of silver or silver alloy;

--- Other protective layer of silver;

--- Covering the metal with a silver or silver alloy.

b) Check the tightness and effectiveness of the above-mentioned material made solderless connector.

In all tests, mainly hydrogen sulfide containing atmosphere change value caused by the exposure of the contact resistance performance according to the test sample Evaluation.
