Leakage (immersion) tests are conducted to determine whether materiel is constructed sc that it can ,be immersed in water withcut leakage cf the water intc the enclosure. a I-2 ~s. Penetration (seepage) cf water intc equipment enclosures can result in problems such as: a. Fouling of lubricants between moving parts. b. Formation of electrically conductive bridges which may cause electronic equipment to malfunction or become unsafe tc operate. c?. Corrosion due tc direct exposure to the water or to the relati high humidity levels caused by the water. .vely d.
Diminishment of the burning qualitiea cf explosives, propellants, fuels, etc. I-3 FOR ~ . NOTE: This test method should be applied at the end of the tailcring prccess described in secticn 4 cf this standard. . a. ~. This methcd is used when the teat item is designed to be watertight and may be exposed to partial cr complete immersion in water. This tast may, in some cases, be used to verify watertightneaa in lieu of a rain test, prcvided that the test item configuration ie the same and erosion ia net a problem. ,* o METHOD 512.2 19 July 1983 512.2-1
