17、R FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These methods of re tests are applicable to swinging door assemblies, including door frames with lights and panels, of various materials and types of construction for use in wall openings to retard the passage
18、 of re. The method does not provide an evaluation of a swinging door assembly when that assembly is part of a larger assembly (e.g. sliding re door assembly), or when it is intended to be used as an elevator entrance. 1.2 Tests made in conformity with these test methods are intended to register perf
19、ormance during the test exposure; but such tests shall not be construed as determining suitability for use after exposure to re. 1.3 It is the intent that tests made in conformity with these test methods allow for the development of data to enable regulatory bodies to determine the suitability of do
20、or assemblies for use in locations where re resistance of a specied duration is required. 1.4 These methods are intended to evaluate the ability of a door assembly to remain in an opening during a predetermined test exposure. 1.5 The tests expose a specimen to a standard re exposure controlled to ac
21、hieve specied temperatures throughout a specied time period, followed by the application of a specied standard re hose stream. The exposure, however, is not representative of all re conditions, which vary with changes in the amount, nature, and distribution of re loading, ventilation, compartment si
22、ze and conguration, and heat sink characteristics of the compartment. It does, however, provide a relative measure of re performance of door assemblies under these specied re exposure conditions. 1.6 Any variation from the construction or conditions that are tested is capable of substantially changi
23、ng the performance characteristics of the assembly. 1.7 The methods do not provide the following: a) Full information as to performance of all door assemblies in walls constructed of materials other than those tested. b) Evaluation of the degree by which the door assembly contributes to the risk of
24、re by generation of smoke, toxic gases, or other products of combustion. c) A temperature limit on the unexposed side of the door assembly. d) A limit on the number of openings allowed in glazed areas or of the number and size of lateral openings between the door and frame. e) Measurement of the deg
25、ree of control or limitation of the passage of smoke or products of combustion through the door assembly. Note: See limitations for the passage of smoke detailed in the Standard for the Installation of Smoke Door Assemblies and Other Opening Protectives, NFPA 105. JUNE 9, 2016 POSITIVE PRESSURE FIRE

Values in parentheses are explanatory or approximate informat
27、ion. 2.2 Undated references 2.2.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. CONTROL OF FIRE TESTS 3 Furnace Construction 3.1 Furnace size 3.1.1 The furnace shall be able
28、 to accommodate the full-sized sample. Small-scale size furnaces are capable of being used for testing small but full-sized samples or representative features of full-sized samples. The furnace face shall be greater in area than the exposed face of the sample by at least 20 percent. The additional a
29、rea between the sample and the furnace shall be lled by wall or partition construction. 3.1.2 The furnace shall have a chamber depth, i.e. the distance between the exposed face of the specimen and the face of the furnace lining immediately opposite the specimen, of not less than 23 in (584 mm) and n
30、ot more than 51 in (1296 mm). 3.2 Furnace construction materials 3.2.1 The furnace shall be constructed of materials which have a greater resistance to heat ow through the other three sides than through the sample. 3.3 Furnace burners 3.3.1 The furnace shall be heated with burners that are red using
31、 either natural gas or liqueed petroleum gases. 3.3.2 The heat output of the burners shall be controllable and shall expose the specimen to a uniform heating as specied in 4.1.1. 3.3.3 The burners shall function so that the fuel gas is introduced into the furnace where the gas mixes with air present
32、 in the furnace and then burns; or, as an alternate, the fuel gas is mixed with air prior to its ignition in the furnace.

33、4 Time-Temperature Curve 4.1 General 4.1.1 The re exposure of door assemblies shall be controlled to conform to the applicable portion of the standard time-temperature curve shown in Appendix A. The points on the curve that determine its character are: 1000F (538C) at 5 minutes 1300F (704C) at 10 mi
34、nutes 1462F (795C) at 20 minutes 1550F (843C) at 30 minutes 1638F (892C) at 45 minutes 1700F (927C) at 1 hour 1792F (978C) at 1-1/2 hours 1850F (1010C) at 2 hours 1925F (1052C) at 3 hours 2000F (1093C) at 4 hours 4.2 Uniformity of temperature distribution 4.2.1 At any time after the rst 10 minutes o
35、f re exposure, the temperature rise indicated by any of the thermocouples used to determine the furnace temperature shall not differ from each other by more than 270F (150C). With test constructions where either the sample or any associated construction incorporates combustible materials that produc
36、e aming within the furnace or where excess air drawn into the furnace is identied as causing localized heating or cooling of one or more of the furnace thermocouple hot junctions, the deviation of temperature rise from each other recorded by the thermocouples so affected shall not exceed 450F (250C)

JUNE 9, 2016 POSITIVE PRESSURE FIRE TESTS OF DOOR ASSEMBLIES - UL 10C 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 5 Furnace Temperatures 5.1 The temperatures of the test exposure shall be the average temperature obtained by a minimum
38、of three thermocouples and no fewer than one thermocouple per 15 square feet of test assembly exposed to the furnace symmetrically disposed and distributed to show the temperature near all parts of the test assembly, Figure 5.1. The thermocouples shall be protected by: (1) sealed 1/2 in (12.7 mm) wr
39、ought-steel or wrought-iron pipe of standard weight or (2) Inconel 600 series schedule 40 pipe (0.8 inch OD / 0.6 inch ID, 20 mm OD / 15 mm ID). 5.2 The junction of the thermocouples shall be initially located 6 in (152 mm) from the exposed face of the test assembly or from the construction in which
40、 the assembly is installed. During the re exposure, if the movement of the test sample causes the samples distance to the thermocouple junction to vary, the location of the junction shall be reset to 6 in (152 mm) at intervals not exceeding 10 minutes during the rst 30 minutes of the test. Thereafte
41、r, the intervals are to be increased to not more than 30 minutes. 5.3 The temperatures shall be read at intervals not exceeding 1 minute. 5.4 The accuracy of the furnace control shall be such that the area under the time-temperature curve, obtained by averaging the results from the thermocouple read
42、ings, is within 10 percent of the corresponding area under the standard time-temperature curve for re tests of 1 hour or less duration, within 7.5 percent for those over 1 hour and not more than 2 hours, and within 5 percent for tests exceeding 2 hours in duration. 5.5 For a summary of the accuracie

44、face Temperatures and Cotton Pad Test 6.1 Unexposed surface temperatures are to be recorded, and are to be determined in accordance with 6.2 6.9. Exception: Single-layer metal doors need not comply with the requirements of 6.2 6.9. 6.2 Unexposed surface temperatures shall be taken at not less than t
45、hree points, with a minimum of one thermocouple in each 16-ft 2 (1.5 m 2 ) area of the door. Thermocouples shall not be located over reinforcements extending through the door, over glass panels, or nearer than 12 in (305 mm) from the edge of the door. 6.3 Surface temperatures of test specimens are t
46、o be measured by means of thermocouples with a wire diameter of not more than 0.03 in (0.7 mm). Each thermocouple is to be brazed to the center of the face of a copper disk 1/2 in (12 mm) in diameter and 0.01 in (0.2 mm) thick, which is secured to the surface of the specimen at the required position
47、. 6.4 Unexposed surface temperatures are to be measured with thermocouples placed under exible, oven-dry, felted pads. The properties of these felted pads are to comply with the requirements specied in Table 6.1. The felted pads are not to break when shaped to contact the surface against which they
48、are placed.
