Standard Test Method for Determining the Hiding Power of Paint by Visual Evaluation of Spray Applied Coatings

Importancia y uso:

5.1 This test method determines hiding power of a test paint by visual evaluation of a spray applied coating.

Note 1: Test Method D2805 describes an instrumental method for determining hiding power. The paint film is applied at a uniform thickness (for example with a doctor blade), the film thickness is measured rigorously, and the opacity is determined photometrically. Hiding power is thereby determined with a high degree of precision.

5.2 Test Method D6762 is less precise than Test Method D2805, but is commonly used since it is more closely related to the application characteristics of the paint and is simpler in concept and evaluation.
