Plastics. Determination of permanganate absorption number of caprolactam. Spectrometric method Ingestion-build-133579 ISO 20848‑3 discusses plastic drums1 Scope This International Standard specifies a spectrometric method for the determination of the permanganate absorption number of caprolactam for industrial use. The permanganate absorption number is a measure of the oxidizable impurities in caprolactam, determined in a buffered neutral aqueous medium under fixed conditions. The method is applicable to purified caprolactam (and intermediates in the caprolactam purification process) with an
