Electronic & electrical component parts: Salt Spray (Corrosion)
This MIL standard had been revised and re-issued several times, with each issue being designated a new sequential suffix letter, which appears after the main standard number. With each revision the method number specific to this particular test may have changed, but the method itself is generally as follows:
Can be used to test the relative resistance to corrosion of coated and uncoated specimens, when exposed to a salt spray climate at an elevated temperature.
Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of neutral (pH 6.5 to 7.2) salt water solution, which falls-out on to the specimens at a rate of 0.5 to 3.0ml/80cm²/hour, in a chamber temperature of +35C. This climate is maintained under constant steady state conditions. The test duration is variable.
