Standard Test Methods for Assay of Organic Peroxides

2017-07-14 /Historical
Superseeded by:
Significance and Use:

3.1 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.


1.1 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 Safety Data Sheets (SDS) for detailed information concerning toxicity, first-aid procedures, and safety precautions.
