Note:
- If organic oxygen compounds would be added, the oxygen content of which should not be more than 2.7% (m/m), and be tested as per SH/T 0663.
- Mangan content measured should not be more than 0.018 g/L, in accordance with Annex B.
- No iron would be added on purpose. It could be entrained during refining and transporting/storing period, its content should not be more than 0.01 g/L in accordance with Annex C.
- Form the 1st July, 2000 on, all the lead-free gasoline to be sold in Beijing, Shanghai and Guangzhou shall be added with effective gasoline cleansing agent.
1)Maximum limit of lead content is specified in this standard, but no lead should be added on purpose. No colouring pigment is added in lead-free gasoline in order to distinguish it from leaded gasoline. In consideration of no leaded gasoline being produced in China from the 1st Jan. 2000 and no leaded gasoline is allowed to have a max. content of lead as 0.013 g/L in gasoline station before the 1st July 2000.
2)It is allowed to measure existent gum according to GB/T 509, but arbitration test shall be based on GB/T 8019.
3)It is allowed to measure induction period according to GB/T 256, but arbitration test shall be based on GB/T 8018.
4)It is allowed to measure sulphur content according to GB/T 17040, but arbitration test shall be based on GB/T 380.
5)In order to meet the environmental protection requirements in large cities, it is specified in this standard that the sulphur content shall be less than 0.08% (m/m) in Beijing, Shanghai and Guangzhou from the 1st July 2000, and in whole China from the 1st Jan. 2003.
6)Pour the sample into 100 mL graduated cylinder, and check it: it should be transparent without any mechanical admixture and water either suspended or sedimented.
7)It will be carried out in Beijing, Shanghai and Guangzhou from the 1st July 2000 and in whole China from the 1st Jan. 2003. |
