Significance and Use
White zinc pigments find considerable use in white paints, and as such it is useful to formulators and users to be able to monitor the amounts of these pigments in whole paints. It is also of interest to raw material suppliers and paint producers to check the specifications of each pigment.
1. Scope
1.1 These test methods cover procedures for the analysis of white zinc pigments.
1.2 The analytical procedures appear in the following order:

| Zinc Oxide |
| Total Zinc, Using Diphenylamine as Internal Indicator | 7 |
| Total Zinc, Using Uranyl Acetate as External Indicator | 8 |
| Total Impurities | 9 |
| Total Sulfur | 10 |
| Moisture and Other Volatile Matter | 11 |
| Leaded Zinc Oxide |
| Total Lead | 12 |
| Total Zinc | 13 |
| Total Sulfur | 14 |
| Total Impurities | 15 |
| Moisture and Other Volatile Matter | 16 |
| Water-Soluble Salts | 17 |
| Zinc Sulfide |
| Zinc Oxide | 18 |
| Zinc Sulfide | 19 |
| Water-Soluble Salts | 20 |
| Moisture and Other Volatile Matter | 21 |
| Barium Sulfate | 22 |
| Titanium Dioxide | 23 |
