UL 10C:2016 pdf free download – STANDARD FOR SAFETY Positive Pressure Fire Tests of Door Assemblies.
9.4 Door frames shall be evaluated when mounted so as to have the doors open either away from or into the furnace chamber, at the discretion of the testing authority, to obtain representative information on the performance of the construction under test.
9.5 Surface-mounted hardware (for example, fire-exit devices and door closers) for use on fire doors shall be evaluated by being installed on one door assembly swinging into the furnace chamber and another door assembly swinging away from the furnace chamber.
CONDUCT OF TESTS
10 Supporting Construction
10.1 Wall construction materials shall have the strength to retain the assembly securely in position throughout the Fire Endurance Test, Section 11, and the Hose Stream Test, Section 12.
11 Fire Endurance Test
11.1 Prior to the start of the endurance test the pressure in the furnace chamber is to comply with Clause
7.2.
11 .2 Within 5 minutes of elapsed time into the fire exposure, the neutral plane of the furnace is to be established at a maximum of 40 in (1016 mm) up from the bottom of the test assembly.
11.3 The pressure that is maintained over the top one-third of the door assembly is not to exceed 0.08 in H20 (20 Pa) over any portion of the test sample.
11 .4 The test is to be continued until the exposure period of the classification or rating being evaluated is reached.
11 .5 The fire endurance test shall follow the fire exposure as referenced in Section 4.
12 Hose Stream Test
12.1 Immediately after and within 3 minutes of the end of the Fire Endurance Test, Section 11, the test assembly is to be subjected to the impact, erosion, and cooling effects of a hose stream directed first at the bottom center and then at all parts of the exposed surface. The hose stream is to be applied with a smooth steady movement of the hose at a rate to ensure all parts of the test assembly are impacted by the hose stream. When all parts of the test assembly have been impacted by the hose stream, the application pattern is to be reversed. See Appendix B for a description of the pattern.
12.2 The hose stream is to be delivered through a 2-1/2 in (63.5 mm) hose discharging through a play pipe as described in the Standard for Play Pipes for Water Supply Testing in Fire Protection Service, UL 385. The minimum water pressure at the base of the play pipe and the minimum duration of application in seconds per ft2 (s/m2) of exposed area are to be as prescribed in Table 12.1.
13 General
13.1 Results shall be reported in accordance with the performance in the tests prescribed in these test methods. The report shall show the performance under the desired exposure period chosen from the following: 20-minute, 30-minute, 3/4-hour, 1-hour, 1-1/2-hour, 3-hour, or 4-hour.
13.2 The report shall include the temperature measurements of the furnace, including their deviation from the specified time-temperature curve and, if determined, of the unexposed side of the test assembly. See 6.1.
13.3 The report shall also contain a record of all observations having a bearing on the performance of the test assembly. Oxygen percentage readings as recorded in 7.7 shall be included in the test report in either tabular or graphic format.
13.4 Any flaming on the unexposed surface of the assembly shall be recorded.
13.5 The amount of movement of any portion of the edges of the door adjacent to the door frame from the original position shall be recorded. See Conditions of Acceptance, General, Section 14, and Specific, Section 15.
13.6 The materials and construction of the door, frame, and wall or partition, and the details of the installation, hardware, door frame and wall anchors, trim, finish, and clearance shall be recorded or appropriately referenced to provide positive identification or duplication in all respects.
