의미와 목적
5.1 많은 건축 코팅, 특히 흰색과 밝은 색상, exhibit significant changes in film opacity when drying. The increase in hiding power is sometimes associated with the porosity and poor film integrity of traditional formulated coatings. Reductions can lead to disappointing paint jobs. 따라서, the change in covering power from wet to dry is a property of great practical importance.

5.2 This test method can be used for paint specifications and as a short procedure for evaluation and quality control.
