Significance and Use:

This test method is intended for use by those in waste management industries to avoid potentially harmful reactions due to oxidizing compounds in wastes.

Scope:

1.1 This test method is intended for use prior to preparation of waste samples for organic analysis. Waste samples that have oxidizing compounds may react with certain reagents in the laboratory (for example, organic solvents).

1.2 This test method is applicable to the analysis of waste liquids, sludges, and solids.

1.3 This test method can neither identify specific oxidizing compounds nor measure concentrations. Since no acid or base is added in this test method, potential oxidizers that require the presence of acid or base will not be detected by this test method.

1.4 It is recommended that, prior to this test, waste samples be screened for water compatibility; see Test Methods D 5058.

1.5 This test method is designed and intended as a preliminary test to complement quantitative analytical techniques that may be used to determine the presence of oxidizers in wastes. This test method offers the ability to screen waste for potentially hazardous reactions due to oxidizer content when the more sophisticated techniques are not available or the total waste composition is unknown.

1.6 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. Specific hazard statement is given in Section and 8 and 11.2.
