This standard provides a test method for the determination of organic peroxides suitable for assessing their suitability for use in chemical intermediates, catalysts and initiators. The method involves the use of sodium iodide for two tests: the test at room temperature is suitable for easily reduced peroxides, and the test at 60 ° C is suitable for medium Stability peroxides. This method helps to ensure that the mass of organic peroxides is suitable for the intended use and requires reference to the safety data table (SDS) before use to ensure safety.
