|Significance and Use|
5.1?Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur-bearing materials are contained in the feedstocks. This test method can be used to determine sulfur in process feeds, sulfur in finished products, and can also be used for purposes of regulatory control.
1.1?This test method covers the determination of sulfur in aromatic hydrocarbons, their derivatives, and related chemicals.
1.2?This test method is applicable to samples with sulfur concentrations to 10 mg/kg. The limit of detection (LOD) is 0.03 mg/kg S and the limit of quantitation (LOQ) is 0.1 mg/kg S. With careful analytical technique, this method can be used to successfully analyze concentrations below the current scope (see ).
Note 1:?LOD and LOQ were calculated using data in ASTM Research Report RR:D16-1060.
1.3?The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice .
1.4?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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. 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.
