\n Significance and Use <\/b><\/p>\n

Phosphorus in gasoline will damage catalytic convertors used in automotive emission control systems, and its level therefore is kept low.<\/p>\n

1. Scope <\/b><\/p>\n

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.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.<\/p>\n

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Section 6 and 9.5. <\/span> <\/span><\/p>\n
