Fecha:
2020-06-22 /Historical
Superseeded by:
Significance and Use:

3.1 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.

Scope:

1.1 These test methods cover procedures for the chemical analysis of blue pigments known commercially as iron blue, copper phthalocyanine blue, and ultramarine blue.

1.2 The analytical procedures appear in the following order:
