25、ire ResistanceRated Floor Systems 2007 Edition This edition of NFPA 288, Standard Methods of Fire Tests of Floor Fire Door Assemblies Installed Horizontally in Fire ResistanceRated Floor Systems, was prepared by the Technical Committee on Fire Tests. It was issued by the Standards Council on July 28
26、, 2006, with an effective date of August 17, 2006, and supersedes all previous editions. ThiseditionofNFPA288wasapprovedasanAmericanNationalStandardonAugust17,2006. Origin and Development of NFPA 288 This test procedure was developed in response to inquiries from outside sources to inves- tigate and
27、 establish a testing procedure for floor fire doors. NFPA 80, Standard for Fire Doors and Fire Windows, had a reference for horizontal access doors. It required these assemblies to be tested in a horizontal position in accordance with the procedure described in NFPA 251, Standard Methods of Tests of
28、 Fire Endurance of Building Construction and Materials (now entitled Standard Methods of Tests of Fire Resistance of Building Construction and Materials). NFPA 251 noted that the test standard did not provide for the effect on fire endurance of conventional openings in the assembly unless specifical
29、ly provided for in the construction tested. This provision limited the testing of the floor fire door to the particular floor/ceiling or roof assembly used. Prior to this test method being developed, some testing laboratories provided testing and labeling of these products. There were many test prot
30、ocols that had to be assumed, which created inconsistency in the testing procedures and listing requirements. This test procedure provides for consistency in the testing and listing of floor fire doors. The test procedure has incorporated provisions from NFPA 251 and NFPA 252, Standard Methods of Fi
31、re Tests of DoorAssemblies, where appropriate. The 2007 edition of NFPA 288 is a reconfirmation of the 2001 edition. 2881 Copyright National Fire Protection Association Provided by IHS under license with NFPALicensee=Purdue University/5923082001 Not for Resale, 10/31/2006 23:43:21 MSTNo reproduction

44、as specified in Section 4.1 shall be the average temperature that is obtained from the readings of not less than nine thermocouples, which are symmetrically disposed and distributed to show the temperature near all parts of the sample. The thermocouples shall be enclosed in protection tubes of such
45、materials and dimensions that the time constant of the protected thermocouple assembly lies within the range of 5 minutes to 7.2 minutes. The exposed length of the pyrometer tube and thermocouple in the fur- nace chamber shall be not less than 305 mm (12 in.). Other types of protecting tubes or pyro
46、meters shall be permitted to be used that, under test conditions, provide the same time range specified above within the accuracy requirement that applies for the measurement of furnace temperature. The junction of the thermocouples shall be placed 305 mm (12 in.) away from the exposed face of the s
47、pecimen at the beginning of the test and, during the test, shall not touch the sample as a result of the samples deflection. 4.2.2The temperatures shall be measured at intervals not exceeding 1 minute during the test period. 4.2.3The accuracy of the furnace control shall be such that the area under
48、the timetemperature curve, obtained by averaging the results from the thermocouple readings, is within 10 percent of the corresponding area as specified in Table 4.1.2 for fire tests of 1 hour or less duration, within 7.5 percent for those tests lasting more than 1 hour and not more than 2 hours, an
49、d within 5 percent for tests exceeding 2 hours duration. 4.3 Temperatures of Unexposed Surfaces. 4.3.1* Measurements. Temperatures of unexposed surfaces shall be measured with thermocouples or with thermometers placed under thermocouple pads. 4.3.1.1 Thermocouple pads shall meet the following require- ments or shall be otherwise demonstrated to be equivalent by comp
