Rubber compounding ingredients — p-Phenylenediamine (PPD) antidegradants — Test methods
This International Standard applies to a variety of substituted p-phenylenediamine (PPD) antidegradants used in the rubber industry. The three general classes of PPD are dialkyl, alkyl-aryl and diaryl, which are used to impart ozone resistance to rubber. The test methods of greatest significance in assessing the purity of production PPDs, and hence their suitability for use in rubber, are specified in this International Standard.

5.1x00a0;This test method is designed to assess the relative purity of production PPDs. These additives are primarily used as antiozonants for tires and other rubber or polymeric products. 5.2x00a0;Since the results of this test method are based on area normalization, it assumes that all components are eluted from the column and each component has the same detector response. Although this is not strictly true, the errors introduced are relatively small and much the same for all samples; thus, they can be ignored since the intent of the test method is to establish relative purity. 5.3x00a0;Although trace amounts of x201c;low boilersx201d; are present in production samples, they are disguised by the solvent peak when using packed columns (Procedure A). 1.1x00a0;This test method covers the determination of the purity of Class I, II, and III p-phenylenediamine (PPD) antidegradants as described in Classification D4676 by gas chromatography (GC) detection and area normalization for data reduction. 1.2x00a0;The values stated in SI units are to be regarded as the standard.
