CHEMICAL AND STAIN RESISTANCE
This test was conducted in accordance with ASTM F 925, Resistance to Chemicals of Resilient Sheet Flooring. By this test, a specified reagent is applied to the surface of the flooring material and allowed to remain in contact for 60 =/- 1 minute. After the exposure of time, the reagent is cleaned from the surface using warm water and the surface dried. Within 5 minutes after removal of the reagent, the material is visually examined and the exposed area compared to the adjacent unexposed area.
The following categories are rated:
!Surface
