Significance and Use
These test methods are suitable for the determination of the ash content of rubber compounding materials. The test methods may be used for quality control, product acceptance, or research and development. Classification prescribes percent ash as an important characteristic of rubber antidegradants.
1. Scope
1.1 These test methods cover the determination of ash content of rubber chemicals.
1.2 The test methods include the following materials:
| Material | Section |
| Sulfur | 7-13 |
| p-Phenylenediamine Antioxidants | 14-22 |
| Benzothiazole Sulfenamide Accelerators | 14-22 |
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
