Fire danger ratings

 

One of the most important indicators of floor coverings is the flame propagation on the surface (FP).

Thus the polyvinylchloride coverings “SOLD” are permitted for using in corridors and halls while linoleum has high fire danger rating (КМ4 and КМ5) and can’t be used on the ways of evacuation.
