OS GSO ISO 8660:2013 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
alkalinity or acidity lower than and a PAN value of up to 35.
