The test standard summaries are for general guidance only. Though believed to be accurate at the time of writing, this may change over time. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.
Note: the terms salt spray, salt mist and salt fog are all in wide spread use within corrosion test standards. In this context they can be considered to be equivalent and interchangeable terms.
DEF STAN 1053 method 36
Can be used to test the relative resistance to corrosion of painted samples, when exposed to an intermittent salt spray climate at an ambient temperature.
Test specimens are placed in an enclosed chamber and exposed to an indirect spray of synthetic sea water solution, which falls-out on to the samples, in a chamber temperature of ambient. The mist (salt spray) is produced daily for 8 periods of 10 minutes, at intervals of 50 minutes, with no spray being applied during weekends.
This test is also referred to as an ‘intermittent’ salt spray test.
