(Test Method)Standard Test Method for Manganese in Gasoline By Atomic Absorption Spectroscopy
Standard Test Method for Manganese in Gasoline By Atomic Absorption Spectroscopy
SIGNIFICANCE AND USE
5.1 Certain organo-manganese compounds act as antiknock agents when added to gasoline. This test method provides a means for determining the concentration of such a material in a gasoline sample.
SCOPE
1.1 This test method covers the determination of the total manganese content, present as methylcyclopentadienyl manganese tricarbonyl (MMT),2 of gasoline within the concentration range from 0.25 mg/L to 40 mg/L of manganese.
1.2 This test method is applicable to reformulated gasoline containing up to 12 % volume methyl tertiary butylether or up to 10 % volume ethanol. This test method may not be applicable to highly cracked materials containing greater than 18 % by volume olefins as determined by Test Method D1319 (nondepentanized).
1.3 This test method has been developed and tested specifically for the determination of MMT in gasoline over the recommended concentration range. Application of the method to other concentration ranges, to the determination of MMT in other materials, or to the determination of other manganese compounds in gasoline have not been tested
1.4 The values stated in SI units are to be regarded as the standard. The preferred concentration units are mg/L manganese.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Sections 6 and 7.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
