Significance and Use
Phosphorus in gasoline will damage catalytic convertors used in automotive emission control systems, and its level therefore is kept low.
1.1 This test method covers the determination of phosphorus generally present as pentavalent phosphate esters or salts, or both, in gasoline. This test method is applicable for the determination of phosphorus in the range from 0.2 to 40 mg P/litre or 0.0008 to 0.15 g P/U.S. gal.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
