ASTM D5007 99 2017 “Standard Test Method para sa mga Pagbabago sa Wet Dry Covering Power”

Kahulugan at paggamit
5.1 Maraming mga pintura ng arkitektura, lalo na ang white at light paints, change significantly in film opacity as they dry. Increased coverage is sometimes associated with porosity and poor film integrity in conventional formulations. The reduction can lead to disappointing paint jobs. Kaya nga, the change in covering power from wet to dry is a property of great practical significance.

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