    ASTM E298

    Significance and Use

    Organic peroxides are widely used as chemical intermediates, catalysts, and initiators. These test methods provide procedures for assaying organic peroxides to determine if they are suitable for their intended use.

    1. Scope

    1.1 These test methods cover the assay of organic peroxides. Two procedures are given, depending upon the ease of reduction:

    1.1.1 Sodium Iodide, Room Temperature Test Method, for organic peroxides easy to reduce, and

    1.1.2 Sodium Iodide, 60°C Test Method, for organic peroxides that are moderately stable.

    1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

    1.3 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.

    1.4 Review the current material safety data sheets (MSDS) for detailed information concerning toxicity, first-aid procedures, and safety precautions.
