| Identification | 6 |
| Moisture by the Brabender Moisture Tester | 7 and 8 |
| Moisture by Toluene Distillation | 9 |
| Water-Soluble Matter by Extraction | 10 |
| Water-Soluble Salts by Electrical Conductivity | 11 |
| Detection of Acid-Insoluble Extenders | 12 and 13 |
| Detection of Acid-Soluble Extenders | 14 to 17 |
| Detection of Organic Colors and Lakes | 18 |
| COPPER PHTHALOCYANINE BLUE PIGMENTS | |
| Identification | 19 |
| Moisture and Other Volatile Matter | 20 |
| Detection of Basic Dye Derivatives | 21 |
| Detection of Other Organic Coloring Matter | 22 |
| Detection of Ultramarine Blue | 23 |
