4.1 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 driers, drying oils, naval stores, and solvents.

Note 1: Test methods for determining the composition of the volatile fraction are not covered by this guide.
