Test Condition - 1
Test Condition-1 is for volatile organic chemical. In this condition, Cotton ball is saturated with the test chemical and placed on the top of work surface. The saturated ball is then covered with a Glass tube of diameter 10mm and length 75mm. The temperature maintained is 25 °C for 24 hours.
Test Condition - 2
Test Condition-2 is for non-volatile chemicals. In this condition, About 4-5 drops test chemical is placed on the work surface and covered with the watch glass of diameter 25mm for 24 hours at 25 °C.
Performance Rating
A – No effect : No detectable change
B – Excellent : Slight change in color or gloss but no change in function or life of the surface.
C – Good : A clear measureable change in the color or gloss but no significant deterioration in surface life or function.
D- Fair : Objectionable change in appearance due to discoloration or etch, possibly resulting in deterioration of function over an extended period of time.
