Significance and Use | ||||||||||
4.1This test method can be used to determine total sulfur levels in process feeds and finished products that fall within the scope of this test method. 4.2Low levels of sulfur in process feed stocks can poison expensive catalysts used in petroleum refining processes. This test method can be used to monitor sulfur levels in these feedstocks. |

1. Scope | ||||||||||
1.1This test method covers the determination of total sulfur in liquid hydrocarbons with a final boiling point less than 450C by gas chromatography using a flame photometric detector. 1.2This test method is applicable for total sulfur levels from 0.5mg/kg S to 100mg/kg S. Note 1:The pooled limit of quantification (PLOQ) derived from
the 2002 interlaboratory cooperative test program was determined to
be 1mg/kg S.
Note 2:Samples can also be tested at other total sulfur
levels, but the precision statements may not apply.
1.3The values stated in SI units are to be regarded as standard. 1.4This 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. 1.5This 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. |
