D6762 Standard Test Method for Determining the Hiding Power of Paint by Visual Evaluation of Spray Applied Coatings
This test method determines hiding power of a test paint by visual evaluation of a spray applied coating.
Note 1—Test Method D 2805 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.
Test Method D 6762 is less precise than Test Method D 2805, but is commonly used since it is more closely related to the application characteristics of the paint and is simpler in concept and evaluation.
1.1 This test method provides for the quantitative visual determination of the film thickness required to achieve full hiding. This film thickness is considered to be the hiding power of a test paint.
1.2 This method applies only to spray applied coatings but its concepts are valid for other methods of application as well.
