1. New standard pour point index: the pour point of all grades No. 10 and above is revised from no higher than -9 to no higher than -6, and note b ( can be negotiated with the user).

2. New standard flash point index: No. 3 crude white oil flash point is revised from no less than 38 to no less than 65; No. 5 crude white oil flash point index is revised from no less than 70 to no less than 65. Lower than 110; the flash point indicator of No. 7 crude white oil was revised from no less than 80 to no less than 120; the flash point of No. 5 and No. 7 crude white oil was changed from closed flash point to open flash point.
