				  hazardous than class A, except for necessary wood doors and wood
				  trim.
(2) Folding-type partitions
				  when used as separations in rooms or between rooms shall be made of
				  noncombustible material, except that impregnated wood or other material that
				  conforms to the criteria of a class B finish material is acceptable.
(3) The alphabetical classification of finish
				  materials is for flame spread, fuel contribution, and smoke development as
				  determined by the tunnel test in accordance with the provisions of national
				  fire protection association standard 255-1972, ASTM-E-84-1968, or UL-723-1973
				  and grouped as follows:
Flame Fuel Smoke

C 76 - 200 76 - 200 126 - 200
(4) The same alphabetical classification is
				  used for the combustibility of prefabricated acoustical tile units only, under
				  federal specifications SS-A 118B-1958.

				  The classification of interior finish materials as to their flame spread and
				  smoke development shall be that of the basic material used without regard to
				  subsequently applied paint or other covering, except where paint or other
				  covering is of such character or thickness or so applied as to materially
				  affect the flame spread and smoke characteristics. Highly combustible material
				  applications, such as lacquer or pyroxylin base materials, and unapproved wall
				  coverings shall not be used.
(8)
				  Paints or coatings that contain plastics, polyesters, or epoxies may be used on
				  noncombustible surfaces without proof of classification if they are not applied
				  in excess of 8 mils total thickness.
(9) Any new floor covering assembly shall be,
				  at a minimum, a class B material.
