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.

3 Test Equipment

3.1 Overview Test equipment including climate system, test box, gas delivery systems, and gas concentration measurement apparatus, see Appendix A. 3.2 Test Chamber Annex chamber and materials used should not absorb or react with hydrogen sulfide, and does not affect the effect of corrosion test gas. gas Walkout chamber by a sufficiently large diameter pipe, the total flow through the gas chamber enables gas tank replacement 3-5 times per hour. box Exhaust gas is allowed to enter within the laboratory. The specific requirements of the chamber structure (including means of generating test gas) must meet the following conditions. a) within the scope of the conditions of the test chamber space where the test sample should be specified; b) should not be directly subjected to the test sample into the impact of air; ......
