Abstract

This international standard specifies a method for quantifying the total unsaturation of polyetherpolyols for use in the production of polyurethanes by Raman spectrometric method. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group.
