The salt-water corrosion test is used to evaluate submarine splice closures. For this test a spUce closure tuid its outer housing are immersed in aerated 3.5 % sodium chloride solution for 180 days. The test is described in TA-TSY-041 [17]. The same closures are also exposed to a similar test using artificial fresh water (ASTM D 2570, Method for Simulated Service Corrosion Testing of Engine Coolants). 

Laboratory tests to determine the behavior of materials and corrosivity of automotive fluids such as engine coolants, engine oils, automatic transmission fluids, and fuels involve exposure to the actual fluid as close to operating conditions as possible. In most cases, aging of the fluids due to their functional use produces a more corrosive liquid therefore it is important that the test be conducted on used liquids or that aging of the fluid occur in-situ. Simple immersion tests can be used if chemical and physical environmental effects are introduced. This is not always possible and therefore simulated service tests have been developed. These laboratory bench tests simulate more...
