ASTM D2805 enables the measurement of hiding power by standardizing the method of assessment using reflectometry, rather than relying on arbitrary visual indicators. One of the attributes of paints and coatings most crucial to them is hiding power, as it defines how well a paint covers the surface. Poor or uneven opacity may result in poor finish, wastage of materials, and lower satisfaction of the customer. Using this reflectance, this method provides a numerical determination of the contrast ratio of the paint film, a quantitative measure of performance coverage, providing an exact ratio of coverage. It is commonly employed in the manufacture, quality control laboratories, and research facilities to ensure homogeneity and the ability to optimize paint formulations.
Get Certified ASTM D2805 for Paint Hiding Power
ASTM D2805 certification guarantees standard measurement of the hiding power of paints by reflectometry. Conformity ensures that the appearance and quality of coatings are consistent with sufficient coverage of the surface. This test method is available in ASTM International and is common in quality control and the manufacture of paint.
