1 Scope and purpose

The test. --- In order to evaluate the atmospheric sulfur dioxide pollution accelerated test method provides a point of contact and corrosion of the connecting member; --- Particularly suitable for comparison test; --- Not as a routine corrosion tests. That is, it may not be possible to predict the point of contact and connections in industrial atmospheric corrosion behavior. Note. In view of the information obtained from accelerated corrosion tests are limited, pay special attention to this test guide GB/T 2424.11 is given. And with reference to GB/T 2424.10. The purpose of this test is. a) to determine the effects of exposure to the performance of a gas containing sulfur dioxide precious metal or precious metal plating of contacts and connections, excluding Some elements of silver and silver alloy composition. b) examine the validity and robustness of solderless connector. In all tests, the connector is exposed to test gas and sulfur dioxide Caused by contact resistance variation can be used as the main performance criteria.

3 Test Equipment

3.1 Overview Test equipment including climate system, test box, gas transmission systems, and gas concentration measurement apparatus, see Appendix A. 3.2 Test Chamber Annex chamber and materials used should not absorb or react with sulfur dioxide, it does not affect the effect of corrosion test gas. air Mixed gas and sulfur dioxide gas by pipeline sufficiently large diameter out of the chamber, the total flow through the gas chamber enables gas tank Replace the body 3 to 5 times per hour. Exhaust gas tank is not allowed into the lab. The specific design of the chamber (including means of generating test gas) must meet the following conditions. a) the conditions of the test chamber space where the test sample should be within the specified range; b) should not be directly subjected to the test sample into the impact of air; c) the average relative rate test gas sample shall be 20m/h ~ 60m/h (about 6mm/s ~ 17mm/s) or slowly Stirring gas, so that the relative rate of all the tested samples of approximately the same gas; d) the test chamber is not allowed condensation phenomena; e) Avoid direct sunlight test chamber, the test chamber and any one of the exposed surface illuminance (from daylight or incandescent or fluorescent
