3.1 The nonvolatile content of raw materials may be used to determine the total nonvolatile content (solids) of paint and related coatings. Such information may be useful to coatings producers and users for the determination of the total solids available for film formation and for the estimation of the volatile organic content.
1.1 This guide is intended to aid in the selection of the proper ASTM test method for determining the volatile and nonvolatile content of pigments.
Note 1: Test methods for determining the composition of the volatile fraction are not covered by this guide.
1.2 The standards included are as follows:
| Standard | Section | ASTM Designation |
| Inert or low hiding pigments | 4.1 | D280 |
| White pigments | 4.2 | D280 |
| Black pigments | 4.3 | D280 |
