Plastics-Polyols for Use in the production of polyurethanes- Determination of degree of unsaturation value by using Iodine method

General information

Current stage: 30.00 Effective date: Sep 13, 2022

Originator: ISO

Owner: ISO/TC 61/SC 12

Type: International Standard

Scope

This international standard specifies a method for quantifying the total unsaturation using an addition reaction of the interhalogen compound ICl (iodine monochloride) using glacial acetic acid as a solvent as a method for measuring the total unsaturation of a polyether polyol for polyurethanes. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group
