Standard Test Method for Flammability of Surface Finishes

Importancia y uso:

5.1 This test method provides a means for evaluation of the flammable performance of surface finish materials.

5.2 A specimen of the surface finish of concern is mounted on the support material contemplated for use and subjected to a controlled significant radiant-flux exposure.

5.3 All specimens are tested while mounted in a vertical plane.

5.4 The following surfaces are exposed to test:

5.4.1 Specimens having surface veneers, fabrics, or painted finishes are tested on one or both exposed sides.

5.4.2 Ceiling finish materials shall be tested on the lower exposed surface.

5.4.3 For ceiling finish materials which are perforated and air backed, tests also shall be conducted on the back (upper) surface of the material.

5.4.4 Floor finish and flooring materials are tested on the upper exposed surface.

5.4.5 Protective membranes or finishes on insulation materials are tested on the air-exposed face or faces.

5.5 This test method provides fire properties that relate to the flammability of the specimens tested. These include ignitability, heat exposure for continued burning, critical flux at extinguishment, and heat-release behavior under varying flux-exposure conditions applied.

5.6 This test method does not provide:

5.6.1 Full information on fire properties of surface-finish materials supported by backing materials other than those tested.

5.6.2 Full information on surface-finish materials when used in other thicknesses than those tested.

5.6.3 Methods for using the fire property measurements as a measure for classifying the fire risk or hazard of the specimens tested.
