Looking at the Specs
Designers looking at flooring spec for the first time may
find the nomenclature mysterious. Lets demystify it.
A typical commercial vinyl flooring spec reads something like
this:
Type: ASTM F 1066-99, Composition 1, non-asbestos formulated;
12 inch by 12 inch; 1/8 [3/32] inch gage; minimum .45 CRF
per ASTM E 648; maximum smoke density of less than 450 per
ASTM E 662; static load limit of 125 psi or higher; minimum
slip resistance rating per ASTM D 2047.
ASTM F 1066-99 (the final figure refers to the most recent
standard update, in this case in 1999) is the American Society
for Testing and Materials standard for most vinyl flooring.
Composition 1, or Class 1, means that the surface pattern
of the flooring runs through the entire thickness of the product.
By federal law, vinyl flooring can no longer contain asbestos.
No one manufactures a product in the U.S. that does contain
asbestos, and you cannot buy one, but specifications still
contain the caveat.
Minimum .45 CRF refers to the critical radiant flux
(CRF) of the flooring surface, and ASTM E 648 refers to the
testing procedure for CRF.
Maximum smoke density of less than 450 is the ASTM spec every
manufacturer must meet to govern the volume of smoke generated
by the flooring in a fire.

Static load limit is usually measured by ASTM F 970. In recent
years, several modified versions of ASTM F 970 have been created
to provide a broad range of static indentation performance.
Higher ratings should be expected from enhanced or solid vinyl
tile. When comparing psi ratings, be sure identical tests
were conducted, i.e. how was the standard test method changed.
To accommodate equipment such as motorized beds in hospital
rooms, designers most often turn to a homogeneous
flooring product.
