    Significance and Use

    4.1 Titanium dioxide pigments are components with high refractive index that significantly influence the opacity, color, durability, and other properties of coatings. This test method for determining titanium dioxide content is quicker and easier to use than Test Methods D1394, a wet chemical analysis method for pigments. It is conveniently applicable to single samples and to large numbers of samples. Only a single relatively stable reagent used to prepare standards and paints under test need be stored. Drawdown specimens used as standards, once prepared, can be stored indefinitely and used repeatedly.

    1. Scope

    1.1 This test method covers the determination of titanium dioxide content in liquid paint. This test method is applicable to both water-reducible and solvent-reducible paints.

    1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 7.
