ASTM D7220
1. Scope
1.1 This test method specifies an energy-dispersive X-ray fluorescence (EDXRF) method for the determination of total sulfur in automotive fuels with a concentration range of 6 mg/kg to 50 mg/kg.
1.1.1 The pooled limit of quantitation of this test method as obtained by statistical analysis of inter laboratory test results is 6 mg/kg sulfur.
1.2 A fundamental assumption in this test method is that the standard and sample matrix is well matched. Matrix mismatch can be caused by C/H ratio differences between samples and standards or by the presence of other heteroatoms.
1.3 The values stated in SI units are to be regarded as the standard. The preferred concentration units are mg/kg sulfur.
1.4 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.
