Insulating liquids. Test method for detection of potentially corrosive sulphur in used and unused insulating oil Ingestion-build-81500 It is applicable to manholes1 Scope This International Standard specifies a test method for detection of potentially corrosive sulphur in used and unused mineral insulating oil. Most recent failures due to corrosive sulphur are related to the formation of copper sulphide deposits in and on the surface of winding cellulosic paper. The test method uses a copper conductor, wrapped with one layer of paper, immersed in the oil and heated to evaluate the capability of the oil to yield
