Organization: ASTM International
Publication Date: 1 January 2015
Status: inactive
Page Count: 4
ICS Code (Rubber compounding ingredients): 83.040.20
significance And Use:

3.1 The pH level of a carbon black is known to affect the vulcanization of some rubber compounds.

scope:

1.1 These test methods, Test Method A-Boiling Slurry and Test Method B-Sonic Slurry, are used to indicate the pH of the carbon black surface by measuring the pH of water in contact with the carbon black.

Note 1: The pH of the carbon black is often used in this industry to indicate the relative acidity or alkalinity of carbon black and will be used in the remainder of these test methods to describe this property.

Note 2: Test Method A and Test Method B do not always give the same results.

1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
