18、FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 The method of test specied in this standard is intended to determine the uplift resistance of roof assemblies consisting of the roof deck and roof covering materials. It is applicable to any type of roof assembl
19、y which is adaptable to the test equipment. Tests to evaluate other potential hazards of roof assemblies are not within the scope of these requirements. 1.2 The purpose of this test is to evaluate the comparative resistance of roof assemblies to positive and negative pressures. 1.3 The test evaluate
20、s the roof deck, its attachment to supports, and roof covering materials. It does not evaluate roofs adjacent to chimneys, overhanging eaves, or similar construction, connections of the assembly to main structural supports (girders, columns, or other supports), structural integrity of secondary supp
21、orts (purlins, joists, bulb tees, or the like), or deterioration of roong materials. 1.4 Deleted July 9, 2009 2 General 2.1 Units of measurement 2.1.1 If a value for measurement is followed by a value in other units in parentheses, the rst stated value is the requirement. 2.2 Undated references 2.2.

23、M UL TEST APPARATUS 3 General 3.1 The test apparatus is to consist of three sections which include a top section to create a uniform vacuum, a center section in which the roof assembly is constructed, and a bottom section to create a uniform positive pressure. See Figure 3.1. Each section is to be s
24、ealed to maintain the specied pressures. This is generated text for gtxt. 3.2 The inside dimensions of the test apparatus are to be a minimum of 10 by 10 feet (3.05 by 3.05 m). 3.3 The test chamber is to be capable of applying steady positive pressures on the underside of the test assembly and both
25、steady and oscillating negative pressures, as specied, upon the top surface. 3.4 Recording equipment is to be used to make a permanent record of the pressure levels developed in the test as a function of time. 3.5 Sections46contain a specication of the presently used test apparatus. Design modicatio

A 4-1/2 inch (114 mm) wide by 1/4 inch (6.4 mm) thick steel plate is to be welded around the
28、 top of the chamber. 4.1 revised July 9, 2009 4.2 The oor of the pressure chamber is to be fabricated from 1/8 inch (3.2 mm) thick sheet steel, welded at the seams and supported by ve 3- by 7.5-inch (76- by 190-mm) steel shapes. The chamber is to be supported by an MC8 x 20 channel at each side and
29、a W8 x 28 beam at each corner. 4.3 Several windows constructed of break-resistant glazing material are to be installed in the chamber walls to allow observation of the underside of the test assembly. 4.4 Flood lights are to be mounted in the chamber for illumination of the under surface of the test
30、assembly. 4.5 Air is to be admitted into the chamber through a 6- by 6-inch (152- by 152-mm) opening cut into the bottom of the chamber. 4.6 A steel baffle is to be placed over the air inlet opening for even distribution of air pressure. The baffle consists of two vanes with the lower vane measuring
31、 22 by 22 inches (559 by 559 mm) and the upper vane measuring 16 by 16 inches (406 by 406 mm). The vanes are set at an angle of 30 degrees from the horizontal. 4.7 Air is to be provided by a blower attached to a 3 horsepower (2.2 kW output) electric motor that is capable of delivering 862 cubic feet
32、 (24.4 m 3 ) of air per minute at a static pressure of 11 inches (2739 Pa) of water. 4.8 The pressure blower starter controls are to be located on the side of the chamber for ease of access and rapid shut down. 4.9 The inlet pressure is to be controlled at the blower by a manually operated steel dam
33、per measuring 2 by 18 inches (51 by 457 mm) which is mounted on a sheet steel collar. The chamber pressure is to be controlled by an automatic relief damper measuring 4-3/4 by 11-3/4 inches (121 by 298 mm) located on the bottom of the chamber. The automatic damper is to be controlled by means of an
34、adjustable weight system. 4.10 The air pressure is to be measured at ve points by means of 1/4 inch (6.4 mm) outside diameter copper tubing extending from the oor into the chamber at an angle of 45 degrees from the oor. Each of four tubes is to be diagonally located 42 inches (1067 mm) from a corner
35、 of the chamber. A fth tube is to be located 18 inches (457 mm) from the center of the air inlet opening. The end of each tube is to be 7 inches (178 mm) above the chamber oor. The tubes are to be connected through 1/4 inch valves into a manifold that, in turn, is to be connected to a manometer havi
36、ng a range of01 2inches of water (0 2988 Pa), graduated into 0.10 inch (24.9 Pa) increments.

37、m chamber is to be formed from C12 x 30 channels and is to measure a minimum of 10 by 10 feet (3.05 by 3.05 m) by 12 inches (305 mm) high at the base. A 4-1/2 inch (114 mm) wide by 1/4 inch (6.4 mm) thick steel plate is to be welded to the bottom of the channels. A reinforced hood, constructed from
38、0.105 inch (2.66 mm) thick steel with 2-1/2- by 2-1/2- by 1/2-inch (64- by 64- by 12.7-mm) angles at the corners and 2-1/2- by 2-3/4-inch (64- by 70-mm) tee sections at the center, is to be mounted on the base. 5.1 revised July 9, 2009 5.2 Several windows constructed of break-resistant glazing mater

40、e terminated in a 24- by 24-inch (610- by 610-mm) metal platform constructed from 1/8 inch (3.2 mm) thick steel plate. A 7 inch (178 mm) diameter opening is to be cut into the plate for the blower. 5.5 Negative pressure is to be provided by a blower and a 3 horsepower (2.2 kW output) motor which are
41、 to be mounted on top of the chamber with their shafts in a vertical position. The combination is to be capable of delivering 862 cubic feet (24.4 m 3 ) of air per minute at a static pressure of 11 inches (2739 Pa) of water. 5.6 The vacuum blower starter controls are to be located on a platform weld

The damper door is to be moved by means of an air motor hooked to an air line and controlled by pressure switches located in a control console. 5.
43、8 An additional manually controlled sliding damper is to be located on the sloped wall of the chamber. It is to be constructed of 1/8 inch (3.2 mm) thick steel plate and a screw gear which opens or closes the damper by turning. The damper is to measure 6 by 18 inches (152 by 457 mm). 5.9 Sheet metal
44、 baffles are to be located on the underside of the damper to prevent direct air ow onto the test assembly. 5.10 The air pressure is to be measured at ve points by means of 1/4 inch (6.4 mm) outside diameter copper tubing extending from the oor into the chamber at an angle of 45 degrees from the oor.
45、 Each of four tubes is to be diagonally located 18 inches (457 mm) from a corner of the chamber. The ends of these four tubes are to be 8 inches (203 mm) above the chamber oor. The fth tube is to enter the chamber at a point 12 inches (305 mm) from the center of the exhaust opening, and its end is t
