Full Description

This International Standard describes a procedure for the determination of the following anti-degradants in raw synthetic rubbers:

N-alkyl-N'-phenyl-P-phenylenediamine;N-aryl-N'-aryl-p-phenylenediamine;N-phenyl--naphthylamine;poly-2,2,4-trimethyl-1,2-dihydroquinoline.

Extender oils, when present, may interfere.

The method, with modification if necessary, may be applied to the determination of other amine anti-degradants.
