According to the standard requirements of the salt spray test chamber, the test method is as follows:
The continuity of the salt spray test chamber test:
Except as otherwise specified in the technical requirements of the test material or test piece, the test shall be carried out continuously throughout the test. The meaning of the continuous test is: except for the daily necessary inspection, rearranging the sample, removing the test sample, checking the sample, and replenishing the solution in the liquid tank to interrupt the test for a short time, the test box is closed. The test operation process must be arranged to keep these interruptions to a minimum.
Salt spray test chamber test time:
The test time shall be determined according to the technical requirements of the test material or product or agreed by the buyer and the seller. The recommended exposure time is a multiple of 24 hours.
Cleaning test samples:
Unless otherwise specified in the technical requirements of the test material or product, at the end of the test, the samples shall be washed slowly or soaked in clean tap water at a temperature not exceeding 38 ° C in order to wash away the salts deposited on their surfaces, Then dry immediately, using a clean compressed air stream.
Attached:
The salt spray test is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by the salt spray damp heat test chamber equipment to evaluate the corrosion resistance of products or metal materials. The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume of space-a salt spray test box, and use a manual method in its volume to create a salt spray environment to evaluate the quality of the product against salt spray corrosion performance. Compared with the natural environment, the salt concentration of the chloride in the salt spray environment can be several times or tens of times of the general natural environment salt spray content, which greatly improves the corrosion rate. The time is also greatly reduced.
