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 Dulling—indicating that the specimen suffered a loss of gloss
!
Surface Attack—indicating that the specimen suffered surface damage such as softening, warping,
swelling, blistering, peeling, raised, or rough area
! Color Change—indicating that the specimen suffered discoloring or bleaching or both.
Each category is rated as No Change=NC, Slight Change=SC, Moderate Change=MC, or Sever
Change=SC. After 24 hours, the exposed specimens are re-examined and similarly rated.
