ASTM E256-09

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

This test method may be used on organic materials in which the complete conversion to chloride can be accomplished by sodium peroxide bomb ignition, and which contain no other halogens.

1.1 This test method covers the determination of chlorine in organic compounds by sodium peroxide bomb ignition. It is intended for application to samples of organic materials containing more than 0.5 % chlorine. The procedure assumes that compounds containing halogens other than chlorine will not be present.

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 safety precautions, see 6.5.2, Section 7, 8.3, and 8.9.

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

Note 1—Other test methods based on oxygen bomb combustion for analysis for chlorine are described in Test Method D808, Test Method D2361, and Test Method D4208.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
