Standard Test Method for Room Fire Test of Wall and Ceiling Materials and Assemblies
SIGNIFICANCE AND USE
5.1 This fire test is applicable to a description of certain fire performance characteristics in appraising wall and ceiling materials, products, or systems under specified fire-exposure conditions in an enclosure. The test indicates the maximum extent of fire growth in a room, the rate of heat release, and if they occur, the time to flashover, and the time to flame extension beyond the doorway following flashover. It determines the extent to which the wall and ceiling materials or assemblies contribute to fire growth in a room and the potential for fire spread beyond the room, under the particular conditions simulated. It does not measure the contribution of the room contents. (See Appendix X1, Commentary.)
5.2 Flashover shall be considered to have occurred when any two of the following conditions have been attained:
(a) Heat release rate exceeds 1 MW.
(b) Heat flux at the floor exceeds 20 kW/m2.
(c) Average upper layer temperature exceeds 600°C.
(d) Flames exit doorway.
(e) A paper target on the floor auto-ignites.
5.2.1 Time to flashover shall be the time from start of test until the second condition has been attained.
5.3 The potential for the spread of fire to other objects in the room, remote from the ignition source, is evaluated by measurements of: (a) the total heat flux incident on the center of the floor, and (b) a characteristic upper level gas temperature in the room.
5.4 The potential for the spread of fire to objects outside the room of origin is evaluated by the measurement of the rate of heat release of the fire.
5.5 Measurements of the rate of production of carbon monoxide, carbon dioxide, and visible smoke are taken.
5.6 The overall performance of the test specimen is visually documented by full-color photographic records. Video taping of the complete fire test is an acceptable alternative to the photographic record. Such records show when each area of the test specimen becomes involved in the fire.

SCOPE
1.1 This is a fire-test-response standard.
1.2 This test method is intended to evaluate, under specified fire-exposure conditions, the contribution to room fire growth provided by wall or ceiling materials and assemblies, or both. The method is not intended to evaluate the fire endurance of assemblies or fires originating in the wall assembly. The method provides a means to evaluate the effectiveness of thermal barriers in restricting the contribution of combustible materials in the wall assembly to fire growth in a room fire.
1.3 This test method, simulating a fire in the corner of a 2420 by 3630 mm (8 by 12 ft) room containing a single open doorway, provides a means to evaluate the relative performance of specified wall and ceiling materials or assemblies when they are used together in the same relationship within an enclosure, and simulating the manner in which they will be used.
1.4 This test method is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source. It shall, however, be noted that the type, position and heat output of the ignition source will considerably influence fire growth. The thermal exposure conditions from the ignition source specified in this method will result in flashover during the 20 min duration for many common finish materials, in particular if specimens are mounted on the walls and the ceiling (standard configuration).
1.5 This test method provides a means for evaluating wall and ceiling finish materials and assemblies, including panels, tiles, boards, sprayed or brushed coatings, etc. This test method is not intended to evaluate flooring materials or furnishings.
1.6 This method shall be used in conjunction with Guide E603, which covers instrumentation and the general effect of various parameters, and Guide E2067, which deals with full-scale oxygen consumption calorimetry.
1.7 The values stated in SI units are to...
