Plastics-Polyols for Use in the production of polyurethanes — Determination of degree of unsaturation by using Iodine method ISO/DIS 4764

General information

Current stage: 40.99 Full report circulated: DIS approved for registration as FDIS Apr 15, 2024

Originator: ISO

Owner: ISO/TC 61/SC 12 Thermosetting materials

Type: International Standard

ICS: 83.080.10 Thermosetting materials

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
