UL 10B Fire Tests of Door Assemblies
UL 10B Fire Test to Door Assemblies – Standard Scope
- These methods of fire tests are applicable to door assemblies of various materials and types of construction for use in wall openings to retard the passage of fire
- Tests made in conformity with these test methods register performance during the test exposure; and such tests shall not be construed as determining compliance for use after exposure to fire
- It is the intent that tests made in conformity with these test methods develop data to enable regulatory bodies to determine the compliance of door assemblies for use in locations where fire resistance of a specified duration is required.
- These methods are intended to evaluate the ability of a door assembly to remain in an opening during a predetermined test exposure
- The tests expose a specimen to a standard fire exposure controlled to achieve specified temperatures throughout a specified time period, followed by the application of a specified standard fire hose stream. The exposure, however, is not representative of all fire conditions, which vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. It does, however, provide a relative measure of fire performance of door assemblies under these specified fire exposure conditions.
UL 10B Fire Test to Door Assemblies –Standard General
Results shall be reported be reported in accordance with the performance in the tests prescribed in these test method. the report shall show the performance under the specified exposure period chosen from the following:20minute, 30minute,3/4 hour, 1hour, 1-1/2hour, 3hour or 4hour. the report shall include the temperature measurements of the furnace and, when determined, of the unexposed side if the test assembly, it shall also contain a record of all observations having a bearing on the performance of the test assembly.
UL 10B Fire Test to Door Assemblies –Standard time-temperature curve shown
the fire exposure of door assemblies shall be controlled to conform to the applicable portion of the standard time-temperature curve shown. the points on the curve that determine its character are：
1000°F (538°C) at 5 min
1462°F (795°C)at 20 min
1550°F (843°C) at 30 min
1700°F (927°C) at 1 h
1850°F (1010°C) at 2 h
2000°F (1093°C) at 4 h
and the other time
