    Significance and Use

    Peroxy esters are widely used as chemical intermediates, catalysts, and initiators. This test method provides a procedure for assaying peroxy esters to determine if they are suitable for their intended use.

    1. Scope

    1.1 This test method covers the assay of organic peroxides of the peroxy ester type.

    Note 1—Other test methods for the assay of organic peroxides are given in Test Methods E 298, E 475, and E 755.

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

    1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this test method.

    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. Specific hazards statements are given in Section 9.
