ISO/CD 23075

Under development

A draft is being reviewed by the committee.

Will replace ISO 23075:2021

Abstract

This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers:

— aminoketone group;

— naphthylamine group;

— diphenylamine group;

— p-phenylenediamine;

— monophenol group.

The groups of antidegradants are summarized in Table A.1 with the chemical names, the abbreviated terms and the CAS registry numbers.

Extender oils, when present, can interfere.

For poly-2,2,4-trimethyl-1,2-dihydroquinoline, the method provides only an approximation because of its polymeric nature.

This standard contributes to the following Sustainable Development Goals
