Blistering of paint as a result of electrolysis. .. 1-3. AND .~ NOTE: This test ethod should be applied only after the end of the tailoring process described in seotion 4 of this standard. :. a. &@J.@&Q. Salt is one of the most pervasive chemical compounds in the world, It is found in the oceans, the atmosphere, ground surfaoes, and lakes and rivers. It is impossible to avoid exposure to salt. In coaetal regiona, this exposure is intensified; in a marine environment,the exposure reaches a aximum.
As a consequence.,all military materiel will be exposed to some form of salt during its life cycle that may affect its performance. b. Bestrictim (1) The procedure in this method has deficiencies and limitations, such aa: (a) The procedure may not duplicate the effects of a marine atmosphere. (b) It has not been demonstrated that a direct relationship exists between salt fog corrosion and corrosion due to other media., , (c) It has not been demonstrated that withstanding the effects of this test guarantees that the test item will prove to be satisfactory under all corrosive conditions.
(d) This test has proven to be generally unreliable for comparing the servioe life of different materiala or coating conditions. (2) Salt fog may cause corrosion of susceptible materials. Humidity -: and fungus can also cause corrosion; however, their effects differ from salt fog effects and the tests are not interchangeable. C. SewaKU. (see procedure is potentially test should be conducted humidity (although it is General Requirements, Q.4.h.) The salt fog test s damaging to materiel. In most cases, the ealt fog after other climatic tests, especially fungue and generally inappropriate to conduct these teet”aon the and dust testing should follow salt fog testing. same test sample).
