| Summary | This standard specifies the determination of stilbent triazole and its derivative metal deactivator in mineral insulating oil by high performance liquid chromatography (HPLC). This standard applies to benzotriazole and its derivatives as a metal deactivator [N-2 (2-ethylethyl) -aminomethyl-methylbenzotriazine (TTAA), benzotriazol (BTA), 5-methylbenzotriazole (TTA)], and the concentration range is 5mg/kg ~ 500mg/kg. |
