Test methods for quantitative determination of corrosive sulfur compounds in unused and used insulating liquids - Test method for quantitative determination of total corrosive sulfur (TCS) Ingestion-build-100580 with compliance to BS EN1 Scope This part of IEC 62697 specifies a test method for the quantitative determination of total corrosive sulfur (TCS) in unused and used insulating liquids and solid matrices through the conversion of corrosive sulfur species to metal (copper, silver etc.) sulfides. The sulfides formed are quantitatively converted to sulfates; sulfates are determined through turbidity measurement or with ion chromatography. The method is applicable with the
