Significance and Use
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 and purchasing quality control.
1.1 These test methods cover procedures for the qualitative chemical analysis of pigments known commercially as copper phthalocyanine blue and green.
1.2 The procedures appear in the following order:
|Moisture and Other Volatile Matter||6|
|Detection of Basic Dye Derivatives||7|
|Detection of Other Organic Coloring Matter||8|
|Detection of Ultramarine Blue||9|
|Detection of Iron Blue or Chrome Green||10|
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
