Scope

This test method may be used to determine the total sulfur content of unknown organic samples or to assay known sulfur containing organic compounds.

This test method may be used on organic materials in which the complete conversion of sulfur to sulfate can be accomplished by sodium peroxide bomb ignition.

This test method assumes that sulfate is quantitatively measured by precipitation with barium chloride solution.

1.1 This test method covers the determination of sulfur in organic compounds by sodium peroxide bomb ignition. It is intended for application to samples of organic materials containing more than 0.5 % sulfur. The presence of iron may require a separation such as is described.

1.2 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 hazard statements, see 6.6.2, Section 7 and 8.3.

Note 18212;A Test method baseed on an oxygen bomb combustion of petroleum products is described in Test Method D 129.

1.3 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.
