The salt spray tester needs to create the following test conditions: a 5% weight saline solution atomized spray (also known as a "fog" or "thin mist") This is a closed test chamber that contains the tested sample Compressed air enters. Salt spray to make a test sample at a speed of 2.0ml / 80cm 2 / hour to create a "waterfall" 1.0. In general, unless otherwise stated, the pH of this fall should be neutral and controlled, with a pH between 6.5 and 7.2.
Because the test conditions specified by the salt spray test are not typical of a naturally occurring environment, this type of test cannot be used as a "real world" service life predictor of reliable samples. Therefore, it is mainly used in quality audits.
