2.2

FLOORING SYSTEMS

The complete systems, after curing, shall have the following properties

when tested in accordance with the test methods listed for each property.

2.2.1

Latex or Resinous Emulsion Matrix Floor Surfacing

**************************************************************************

NOTE: Resistance to reagents specified in item j.

is required to withstand cleaning agents and

spillage associated with normal use. Where

resistance to specific chemicals associated with

laboratories, plating shops, etc., is required,

these chemical solutions and concentrations should

be added to the lists. Manufacturer's literature

should be checked to assure that the matrix is

capable of resistance to these chemicals.
