The salt spray test chamber is to evaluate the ability of the salt spray corrosion of the material and its protective layer, and the process quality comparison of similar protective layers. At the same time, the ability of some products to resist salt fog corrosion The salt spray corrosion test of electronic components, metal materials and industrial products can be divided into: neutral salt spray test, acid salt spray test, copper accelerated acetate spray test according to the test requirements.
Testing the corrosion resistance of the product during the test is the basic performance of the salt spray box. Through this test, we can understand the product's life characteristics, failure rules, failure rates, average life, and the various possible A failure mode. The life test of the salt spray test chamber is a method to study the life characteristics of products. This kind of simulation is carried out in the salt spray test room by simulating various use conditions.
The repeatability of the salt spray test results depends to a large extent on the test sample and the selected standard, as well as on the control of the operating variables. In some test procedures, a large number of data collection times should be considered to establish the variability of test results. Even if the test conditions are similar and the concentration range of the test is the same, the test results of similar samples are different in the salt spray test chamber of different sample methods.
On the contrary, if the customer is doing the test, in order to shorten the test time of the salt spray test chamber, the test can be carried out by increasing the stress without changing the failure mechanism. This is the accelerated life test. The reliability level of the product can be evaluated through the life test of the salt spray test chamber, and the reliability level of the new product can be improved through the quality feedback of the salt spray test chamber.
While using the salt spray test chamber for testing, in addition to wanting to obtain the most accurate test results, we also need to strengthen the preservation and maintenance of the salt spray test chamber.
