SEPTEMBER 18, 2007 FIRE TEST OF INSULATED WALL CONSTRUCTION - UL 1040 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 This test method describes the testing procedures and requirements applicab

18、le to insulated wall constructions by use of a standardized large-scale corner test. 1.2 The purpose of this test method is to determine the ability of eld or prefabricated insulated wall panels to resist the spread-of-ame over a simulated interior wall surface of a building and the ability of the i

19、nsulating material to resist damage as a result of the re exposure. This test method is not intended to evaluate the re resistance afforded by the structural members of the test structure such as columns, beams, girders, bar joists, tie bars, and the like. 1.3 These requirements do not cover the eva

20、luation of panels intended for various uses other than as specied in 1.1 for which there are other established test standards as follows: a) Surface Burning Characteristics Classication Establishes the comparative burning characteristics of building materials and assemblies by measurement of ame spr

21、ead over exposed surfaces and the density of the smoke developed during the re exposure period. This test method is described in the Standard for Test for Surface Burning Characteristics of Building Materials, UL 723. b) Fire-Resistance (hourly rating) Establishes hourly re resistance ratings of bui

22、lding assemblies through large-scale re exposures under specic loading conditions. This test method is described in the Standard for Fire Tests of Building Construction and Materials, UL 263. c) Roof-Covering Materials Establishes performance measurements for coverings relative to resistance to exte

23、rior re spread and penetration. This test method is described in the Standard for Test Methods for Fire Resistance of Roof-Covering Materials, UL 790. d) Roof-Deck Construction Materials Establishes performance measurements for roong systems with respect to resistance to the spread-of-ame and damage

24、 from underdeck interior re exposure. This test method is described in the Standard for Fire Test of Roof Deck Constructions, UL 1256. 1.3 revised June 8, 2001 1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirem

25、ents in this standard, and that involves a risk of re or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, c

26、haracteristics, components, materials, or systems conict with specic requirements or provisions of this standard does not comply with this standard.

29、FORMANCE LARGE SCALE CORNER TEST 3 General 3.1 A nominal 764 10 pound (347 4.54 kg) wood crib is to be used to produce a uniform ame for direct impingement on the walls and ceiling of a 20 by 20 by 30 foot (6.10 by 6.10 by 9.14 m) high open corner conguration. The contribution of the wall assembly t

30、o re growth is to be dened in terms of: a) The time history of temperature development within the corner conguration; b) The maximum observed ame progression; c) Post-test damage of the sample. 3.2 A report of the test results shall be prepared as specied in Report, Section 10. 4 Ignition Source 4.1

31、 The ignition source for the test is to be a wood crib weighing 764 10 pounds (347 4.54 kg) having dimensions of 4 by 4 by a minimum of 3-1/2 ft high (1.22 by 1.22 by 1.07 m), and constructed of 12 tiers of kiln dried spruce, pine, r, or other soft woods having densities similar to those named, and

32、are to be dried to a moisture content of 9 to 11 percent as determined by the procedures described in paragraph 4.3. Each strip is to be 4 ft. long, and is to have a cross section of trade size 2- by 4-inch nominal 1-1/2 by 3-1/2 inches (38.1 by 89 mm). Within the crib, the strips in each tier are t

33、o be evenly spaced and lie at right angles to the strips in the tier below. 4.1 revised June 8, 2001 4.2 The wood crib is to be positioned 1 foot (305 mm) from each wall and is to be ignited by two torches formed from 3-1/2 inch (88.90 mm) diameter by 6 inch (152.40 mm) long rolls of cotton waste, e

34、ach saturated with 8 ounces (0.23 kg) of n-heptane. The torches are to be ignited simultaneously, inserted immediately into the bottom tier and positioned at the center of one of four quadrants (based on plan view cross-sectional area) for 15 s (30 s elapsed time) and then removed. Ignition time is

35、considered to be the instant the torches are inserted into the wood crib. 4.2 revised June 8, 2001 JUNE 8, 2001 FIRE TEST OF INSULATED WALL CONSTRUCTION - UL 1040 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.3 Moisture content of the w

36、ood is to be monitored by using either a conductance or dielectric-type meter (calibrated as described in the Standard Test Methods for Use and Calibration of Hand-Held Moisture Meters, ASTM D-4444) until the desired level is reached. Final determination of moisture content shall be based on the sec

37、ondary oven-drying method (Method B) described in the Standard Test Methods for Direct Moisture Content Measurement of Wood and Wood-Base Materials, ASTM D-4442. 4.3 added June 8, 2001 5 Fire Test Room and Geometry 5.1 The test structure is to be constructed from the insulated wall construction mate

38、rials under investigation. These materials are to be installed in the required framework so as to form two vertical walls intersecting to describe a 90-degree angle to form a 20 by 20 by 30 feet (6.10 by 6.10 by 9.14 m) high structure. The construction is to be representative of eld construction. Th

39、e two open sides of the test structure are considered to represent the greater open volume of a building. 5.2 An uninsulated at-metal roof, nominally 20 by 20 feet (6.10 by 6.10 m), is to be placed over the test structure. The walls are to be joined to the roof in a manner representative of eld-join

40、ing methods. (Since the presence of combustible material on the underside of the ceiling can inuence the performance of walls, the results of this test are applicable only to constructions with noncombustible material on the interior ceiling surface.) 5.2 revised June 8, 2001 6 Protection and Condit

41、ioning of Test Assembly 6.1 Prior to mounting, specimens are to be conditioned at a temperature of 73 4F (22.8 2.2C) and a relative humidity of 50 5 percent until constant weight is achieved. 6.2 The test assembly is to be mechanically protected during and after mounting to provide for its integrity

42、 at the time of test. Assemblies are not to be tested until nal material conditioning has been attained. Materials containing moisture or solvents are to achieve constant weight condition prior to test. 6.2 revised June 8, 2001 6.3 In addition, 2-foot (0.61 m) high draft curtains are to be suspended

43、 from the underside of the at roof along the open sides of the test structure. The draft curtains are to be composed of noncombustible material. 6.3 revised June 8, 2001 6.4 Deleted June 8, 2001 JUNE 8, 2001 FIRE TEST OF INSULATED WALL CONSTRUCTION - UL 1040 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED F
