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.
