Historical (view previous versions of standard)
Significance and Use
The presence of inorganic chlorides and sulfates in oil in contact with metal surfaces in electrical equipment can result in corrosion of transformer components. The deterioration of metal surfaces is dependent upon the quantity of the corrosive agent and the operating environment. Although not quantitative, this test method is a means for recognizing the potential for such a hazard.
1.1 This test method describes the qualitative determination of inorganic chlorides and sulfates in electrical insulating oils. Note 1 - It should be pointed out that if the strong acids, hydrochloric and sulfuric, are present, they will give positive results for chlorides and sulfates, respectively.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
