16、HOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover clear, translucent, or opaque glazing material intended for indoor and outdoor use principally as a substitute for plate glass show windows or show case panels. 1.2 The material is intended to resist burglarious attacks of the

17、 hit and run type. 1.3 These requirements do not cover the glazing (mounting) methods used for the installation of burglary resisting glazing material. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information.

18、CONSTRUCTION 3 General 3.1 There shall be no defects or visible imperfections in the nished product that may impair its serviceability. PERFORMANCE 4 General 4.1 Representative samples of each construction of glazing material are to be subjected to the following tests. 4.2 Samples of each constructi

19、on, each measuring 24 by 24 inches (610 by 610 mm), are to be used. 5 Sample Conditioning 5.1 General 5.1.1 For the thermal conditioning procedures, all samples are to be conditioned at the specied temperatures for at least 4 hours prior to the applicable impact test. 5.2 Thermal conditioning tests

20、for outdoor use 5.2.1 Three samples of the material are to be conditioned at a temperature of 120F (49C). 5.2.2 Three additional samples are to be conditioned at a temperature of 14F (minus 10C). 5.3 Thermal conditioning tests for indoor use 5.3.1 Three samples of the material are to be conditioned

21、at a temperature of 95F (35C). NOVEMBER 27, 2006 BURGLARY RESISTING GLAZING MATERIAL - UL 972 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 5.3.2 Three additional samples are to be conditioned at a temperature of 55F (13C). 6 Impact Tests

22、 6.1 General 6.1.1 Where thermal conditioning procedures are specied, samples are to be tested immediately upon removal from the thermal conditioning chamber. The samples of the glazing material are to be mounted horizontally in a frame so as to provide uniform clamping on all four edges of the mate

23、rial and an unsupported area of 22 by 22 inches (560 by 560 mm). See 6.1.2. 6.1.2 The frame is to be constructed of 2-inch (51-mm) steel angles, at least 1/4 inch (6.4 mm) thick, welded at all four corners to form a rigid square. The square is to be supported by steel members, at least 8 inches (205

24、 mm) high, at each of the four corners. The entire assembly is to be mounted on a solid wood platform formed of 3/4-inch (19.1-mm) plywood. The four clamping members are to be of the same angle steel as used in the frame. 6.1.3 The part of the frame and clamping members that come in contact with the

25、 test sample are to be lined with hardwood stripping. The wood, in turn, is to be covered with rubber or felt stripping approximately 1/8 inch (3.2 mm) thick. At least two clamps are to be used on each of the four sides to secure the test sample between the frame and the clamping members. 6.1.4 The

26、impacts are to be conducted using a 3-1/4 inch (83 mm) diameter smooth hardened-steel ball weighing 5 lbs (2.3 kg). 6.1.5 During the Ball impact test, Section 6.2; Outdoor use impact test, Section 6.3; and the Indoor use impact test, Section 6.4, the steel ball is to be released so as to strike each

27、 sample successively at ve different locations within a 5-inch (127-mm) diameter circle, the center of which is to be located at the approximate center of the sample. 6.1.6 Except for retrieving the steel ball, or resecuring the clamps, the test sample is not to be disturbed until the specied number

28、 of impacts have been conducted. 6.1.7 During the Ball impact test, Section 6.2; Outdoor use impact test, Section 6.3; and the Indoor use impact test, Section 6.4, if the steel ball falls outside of the 5-inch (127-mm) diameter circle or if the test sample is damaged in handling, the results are to

29、be considered inconclusive and the test(s) is to be repeated using a reserve sample. 6.1.8 The steel ball shall not penetrate the glazing material: a) On any one of the ve impacts on three samples tested as specied in Sections 6.2, 6.3, and 6.4, or b) On any of the single impacts on the three sample

30、s tested during the High-energy impact test, Section 6.5. Penetration is considered to occur if the ball passes completely through the glazing material.

31、HOUT PERMISSION FROM UL 6.1.9 If one of the three samples tested in 6.1.8(a) should fail, three additional samples shall be tested. If the three additional samples pass, the results are acceptable. If one of the three additional samples should fail, results are not acceptable. 6.1.10 If two of the t

32、hree samples tested in 6.1.8(a) should fail, the results are not acceptable. 6.2 Ball impact test 6.2.1 The glazing material shall withstand ve 50-foot-pound (68-J) impacts, as produced by dropping the steel ball specied in 6.1.4 through a vertical distance of 10 feet (3 m). 6.2.2 The test is to be

33、conducted on three samples of the glazing material maintained at room temperature, 70 80F (21 27C). 6.3 Outdoor use impact test 6.3.1 After thermal conditioning as specied in 5.2.1 and 5.2.2, each of the samples shall withstand ve 40-foot-pound (54-J) impacts, as produced by dropping the steel ball

34、described in 6.1.4 through a vertical distance of 8 feet (2.4 m) as described in 6.1.5. 6.4 Indoor use impact test 6.4.1 After thermal conditioning as specied in 5.3.1 and 5.3.2, each of the samples shall withstand ve 50-foot-pound (68-J) impacts, as produced by dropping the steel ball described in

35、6.1.4 through a vertical distance of 10 feet (3 m) as described in 6.1.5. 6.5 High-energy impact test 6.5.1 The glazing material shall withstand one 200-foot-pound (270-J) impact, as produced by dropping the steel ball described in 6.1.4 through a vertical distance of 40 feet (12.1 m). 6.5.2 The tes

36、t is to be conducted on three samples of the glazing material maintained at room temperature, 70 80F (21 27C). MARKINGS 7 General 7.1 The nished glazing material panel shall be plainly marked with the manufacturers or private labelers identication or a distinctive catalog number or the equivalent by

37、 which the product may be readily identied. 7.2 The marking may be located on the protective covering or package of the glazing material panel(s) as shipped from the factory. 7.3 If a manufacturer produces glazing material at more than one factory, each nished glazing material panel shall have a dis

38、tinctive marking to identify it as the product of a particular factory.
