BS ISO 23075:2021

This standard BS ISO 23075:2021 Vulcanized rubbers. Determination of antidegradants by high-performance liquid chromatography is classified in these ICS categories:

• 83.060 Rubber

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

1. aminoketone group;

2. naphthylamine group;

3. diphenylamine group;

4. p-phenylenediamine;

5. 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.
