The new implementation standard for crude white oil will be implemented on October 1, 2019

Learned: On June 4, 2019, the National Energy Administration released The new implementation standards for crude white oil will be implemented on October 1, 2019.

The crude white oil standard was first released on October 27, 2015, and this is the first revision. This standard was proposed by China Petrochemical Corporation and drafted by Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd.

This standard is drafted in accordance with the rules given in GB/T1.1-2009 and replaces NB/SH/T0914-2015 “Crude White Oil”. The new standard is consistent with NB/SH/T0914-2015 The differences are as follows:

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.

3. New standard color index: Cancel note b (can be negotiated with the user).

4. New standard sulfur content indicators: No. 3 and No. 5 indicators are revised from no more than 50mg/kg to no more than 10mg/kg, No. 15 and above indicators are revised from no more than 100mg/kg to no more than 100mg/kg. Greater than 50mg/kg.

5. New standard aromatic hydrocarbon content index: The aromatic hydrocarbon content index has been revised to no more than 10%, and the test method NB/SH/T0966 “Determination of Aromatic Hydrocarbon Content in White Oil by Ultraviolet Spectrophotometry” has been added.

6. New standard nitrogen content index: revised from no more than 500mg/kg to no more than 100mg/kg. The test method for grades 68 and below adopts SH/T0657 “Determination of Trace Nitrogen in Liquid Petroleum Hydrocarbons” Oxidative Combustion and Chemiluminescence Method》�
