3.1 The procedure described is used to observe the behavior of steels under exposure conditions that retard the formation of a protective type of rust. It is also used to evaluate seal coat on insulation.
3.2 This practice should not be used to rank steels that form a protective type of rust under atmospheric exposure conditions.
1.1 This practice covers procedures for conducting cyclic humidity exposures with a corrosive dip.2 It sets forth the conditions required in cyclic humidity testing.
1.2 This practice does not prescribe the type of exposure specimen or exposure periods nor the interpretation to be given to the results.
