3.1 This collection of test methods is used by pigment producers and paint manufacturers for process control, for product acceptance, and for research and development.
1. Scope
1.1 These test methods cover procedures for determining certain properties of pigments. The procedures appear in the following order:
| Dry Pigments | Sections |
| |
| Loss on Ignition and Ash | 4 |
| Matter Soluble in Water | 5 |
| Hydrogen Ion Concentration (pH Value) | 6 |
| Alkalinity or Acidity by Titration | 7 and 8 |
| Water Content (Distillation Method) | 9 and 10 |
| |
| Pigment Pastes in Oil | |
| |
| Water Content (Distillation Method) | 9 and 10 |
| Pigment Content of Paste in Oil | 11 |
| Total Volatile Matter in Paste in Oil | 12 |
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
