  Chemical Properties     

Test method A (for volatile chemicals):
A cotton ball, saturated with the test chemical (reagent), is placed in a 1-ounce test tube with a reservoir of liquid above the ball. The container is inverted on the test material at a standard temperature of 23℃ plus or minus 2℃ (73°plus or minus 4℉).

Test method B (for non-volatile chemicals):
5 drops (1/4cc) of the test chemical are placed on the test material surface. The chemical is covered with a watch glass (d=5cm) at a standard temperature of 23°plus or minus 2℃ (73°plus or minus 4℉).

For both the above methods (A and B), leave the reagents on the panel for a period of: 1 hour for exposed vertical surfaces and semi-exposed surfaces, 24 hours for exposed horizontal surfaces such as countertops. After exposure, exposed areas are washed with water, then a detergent solution, finally with naphtha, then rinsed with distilled water and dried with a cloth.
