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 the safety concerns 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.

12.1 Acid-insoluble extenders include barium sulfate, silica, and silicates. Alumina may also be found, in part, with this group.

14.1 Acid-soluble extenders include the alkaline earth carbonates or sulfates, magnesium carbonate, and alumina hydrate.


These test methods are suitable for determining if impurities are present and establishing that the required pigments are present. These test methods may be used for manufacturing quality control.
