1 .1 This is a fire test method for determining the fire performance response of discrete products (including, but not limited to electrical, mechanical, and plumbing equipment) intended to be installed in air handling spaces, such as above suspended ceilings or below floors. These products are subjected to an open flame ignition source and evaluated using a product calorimeter.
1 .2 This test may be used to determine fire performance and smoke characteristics of discrete,non-continuous building materials where the Test for Surface Burning Characteristics of Building Materials, UL 723, is not applicable.
