Reference standard: GB / T 12085.4-2010 Environmental test methods for optical and optical instruments Part 4: Salt spray, this standard applies to optical instruments, instruments equipped with optical components and optical components; The ability to protect the coating against salt spray was evaluated.
GB / T 12085.4-2010 is suitable for: 1. Evaluating the resistance of optical and other functional coatings to salt spray corrosion; 2. Evaluating the resistance of metal and non-metal coatings to salt spray corrosion; Irrationality.
GB / T 12085.4-2010 is not suitable for the following tests: 1. General corrosion test; 2. Real reproduction of natural marine environment; 3. Assessment of anti-corrosion measures for components and parts separated from installed devices.
Note: The usual salt spray test should not be used to evaluate and compare the corrosion resistance of different materials or the corrosion resistance and service life of coatings exposed to changing weather conditions. To give a comparison of the performance of the laboratory salt spray test with respect to natural conditions (such as the degree to which salt spray accelerates the corrosion rate of the sample), it is necessary to conduct some related tests. For example, aluminum alloy, if it can be confirmed that there is a certain correlation between the field test data and the laboratory salt spray test results, you can get some different samples of the same or close to the metal through this salt spray test, or equivalent or comparable protective coating Working life of different samples.
