Salt spray test is a kind of artificial simulation of salt spray environment test, compared with the atmospheric conditions of exposure test, it has significant advantages, corrosion environment can be controlled, the environment reproducibility is good, greatly saving the test time and human resources and financial resources.Exposing product defects through tests is an essential and important test means in the whole process of new product development, prototype test and product qualification appraisal test.

1. Take out the sample carefully at the end of the salt spray test, rinse the sample gently in clean flowing water (water temperature 38℃) to remove the salt scale on its surface, and then immediately dry the sample with clean compressed air under the pressure of 0.25~0.30MPa.(ملحوظة: the pressure is only used as a reference value, not strictly stipulated).

2, according to the test material or product specifications of the sample after dry treatment of corrosion degree or other problems immediately for a careful inspection, in order to facilitate the evaluation of the results.

3. Test the collection liquid collected by the spray collector (at least 16h).The average spray volume should be calculated by the formula (liquid volume/collection time) : the value should be between 1.0~2.0 mL /h; the specific gravity of the collected liquid should be between 1.0255~1.0400; the pH value of the collected liquid should be between 3.1~3.3.

4, determine the salt spray corrosion performance of the salt spray tester: not more than one corrosion point per square inch (645mm2) on the important surface of the sample, not more than three stains per 25mm edge line, and the size of the corrosion point IN any direction cannot be greater than 0.03 IN (0.8مم).
