The No. 21 Announcement of the National Development and Reform Commission in 2004 approved 28 petrochemical industry standards such as the “Determination of Hydrocarbon Group Composition in Gasolineâ€. Among them, the two standards for determination of hydrocarbon composition in gasoline and sulfur content in gasoline have been implemented since April 30, 2004. The other 26 standards have been officially implemented since September 1, 2004. Because the standards mainly focus on the petrochemical industry's measurement and testing, it is worth the attention of petrochemical companies. The 26 standards are: petroleum wax odor test method, ethylene-propylene-diene rubber (EPDM) evaluation method, industrial cumene, industrial cumene purity and impurities, industrial cumene Determination of peroxide content, determination of phenol content in cumene for industrial use, determination of phenolic compounds and cumene hydroperoxide content in industrial cumene, purity of 1-butene for industrial use and hydrocarbon impurities Determination of trace propadiene and propyne in 1-butene for industrial use, determination of trace amounts of methanol and methyl tert-butyl ether in 1-butene for industrial use, determination of additive elements in lubricants and additives, industry Isobutene, isobutylene purity for industrial use, determination of hydrocarbon impurities, determination of oxygenates in isobutylene for industrial use, determination of isobutylene dimer in isobutylene, acrylonitrile-butadiene rubber (BR) Ä€6. 《 . . 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 (6) Self-employed å³æ£ºé„槌 惴 惴 惴 (6)?
