Fire Test for Heat and Visible Smoke Release for Discrete Procts and Their Accessories Installed in Air-Handling Spaces
UL 2043
1 Scope
1.1 This is a fire test method for determining the fire performance response of discrete procts (including, but not limited to electrical equipment) intended to be installed in air handling spaces, such as above suspended ceilings or below floors. These procts are subjected to an open flame ignition source and evaluated using a proct 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.
1.3 The purpose of this test is to determine the rate of heat release and the rate of smoke release of the burning proct samples as they relate to the requirements for fire-resistant and low-smoke-procing characteristics in accordance with the provisions of the following codes: National Electric Code, NFPA 70; International Mechanical Code, NFPA 5000; Standard for the Installation of Air Conditioning and Ventilating Systems, NFPA 90A.
1.4 This test method does not provide information on the performance of procts in other fire or test conditions. This test does not investigate the toxicity of the procts of combustion.
1.5 This test does not cover the constructional, electrical, or other performance requirements of the proct.
