CONSTRUCTION 5 General 5.1 The enclo
22、sure of a collection and containment system shall be formed and assembled such that it has the strength and rigidity necessary to resist the abuses likely to be encountered during its intended service. The degree of resistance inherent in the system shall preclude total or partial loosening or displ
23、acement of parts, and other serious defects, which alone or in combination constitute a risk of re, explosion, or injury to persons. 5.2 Among the factors taken into consideration if an enclosure is being judged for acceptability are its: a) Mechanical strength; b) Resistance to impact; c) Moisture-
24、absorption properties; d) Flammability; e) Resistance to corrosion; and f) Resistance to distortion at temperatures to which the enclosure may be subjected under conditions of intended or abnormal use. PERFORMANCE 6 Fire Exposure Tests 6.1 Preparation of samples 6.1.1 The wooden deck for the re expo
25、sure tests is to be constructed with nominal one by eight inch pine boards and conditioned as described for Class A and B burning-brand decks in the Standard for Standard Test Methods for Fire Tests of Roof Covering Materials, UL 790. The deck is to be mounted at the maximum incline recommended by t
26、he manufacturer but not greater than an incline of 5 inches per horizontal foot (127 mm per 0.3 m). JULY 10, 2015 UL 710A 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 6.2 Flaming brand test 6.2.1 This test shall demonstrate the effect of
27、 having the system exposed to aming solid particles falling onto the system from a grease duct ventilator. The system shall not sustain combustion and the system shall conne the burning to the immediate area of the brand. Also, there shall be no evidence of burning or ignition of the supporting surf
28、ace. For the purpose of this Standard, sustained aming is considered any aming which continues uninterrupted for 5 seconds or more. 6.2.2 Flaming wood Class C test brands as described in the Standard for Standard Test Methods for Fire Tests of Roof Covering Materials, UL 790 shall be dropped onto th
29、e surface of the rooftop grease and oil collection and containment system. Brands are to be placed at one or two minute intervals. No brand is to be placed closer than 4 inches (102 mm) to the point where the previous brand was located. The lesser of 20 brands or a quantity to cover the surface of t
30、he containment system are to be used. 6.3 Flaming grease test 6.3.1 This test shall demonstrate the effect of aming oil dripping onto the system from a ventilator. The rooftop grease and oil collection and containment system shall not sustain combustion and the system shall conne the burning to the
31、immediate area of the oil drops. Also, there shall be no evidence of burning or ignition of the supporting surface. For the purpose of this Standard, sustained aming is considered any aming which continues uninterrupted for 5 seconds or more. 6.3.2 The system shall be installed on the wooden deck su
32、rface. Eight ounces of vegetable oil shall be ignited and allowed to burn for 20 seconds prior to any drops being made. Drops of the aming oil shall then be allowed to fall on the collection and containment system at intervals of 10 seconds between drops. Each drop is to be no less than 1/4 ounce, r
33、andomly dropped at different locations around the portion of the containment system intended to receive oil. At this rate there should be no more than approximately 32 drops of oil, and test should last for a duration of no more than 5 minutes and 10 seconds. 6.4 Fire exposure test 6.4.1 This test s
34、hall demonstrate the effect the system should have when a ame is applied to the system from an external ame source. The ames shall be conned to the system and there shall be no evidence that the ame is spreading beyond the system and there shall be no evidence of the roof deck, under the system, bur
35、ning. In addition, there shall be no evidence of burning particles blown outside the collection and containment systems enclosure. 6.4.2 The system shall be installed on a roof structure as described in the Standard for Standard Test Methods for Fire Tests of Roof Covering Materials, UL 790. An inte
36、rmittently applied Luminous Gas Flame at a temperature of 1400F (760C) shall be applied for 15 cycles to the system. During this test, the airow shall be maintained at 12 MPH (5.4 m/s).

37、MISSION FROM UL 7 Grease Containment Tests 7.1 Rain test (Dry) 7.1.1 A representative sample of a rooftop grease or oil collection and containment system shall be subjected to an application of simulated rain for one-hour. The test apparatus described for the water spray test in the Standard for Pow
38、er Ventilators, UL 705 shall be used to apply the simulated rain. After the application of the rain, grease or oil shall be dripped onto the system. Water shall drain from the system and have no apparent effect on the ability of the system to absorb oil. 7.2 Rain test (Oil soaked) 7.2.1 A representa
39、tive sample, soaked with oil, shall be subjected to an application of simulated rain for one-hour. The system shall not permit the oil to wash away. After the application of the rain, a cup of oil shall be dripped onto the system and the systems ability to absorb the oil shall be veried. 8 Mechanica
40、l Abuse Tests Impact Tests 8.1 This test is conducted on three representative samples formed from thermoplastics that may affect the performance of the rooftop grease and oil collection and containment system. 8.2 The samples shall withstand the impact described in 8.3 without evidence of damage to
41、the component and the component shall remain structurally sound. 8.3 Each of three samples of the system shall be subjected to a single impact. This impact is to be produced by dropping a steel sphere, 2 inches (50.8 mm) in diameter, and weighing 1.18 lb. (0.535 kg) mass from a height of 51 inches (
42、1.29 m) to produce a 5 ft-lb. (6.78 joules) impact. The steel sphere shall strike the surface in a location different from those in the other two impacts. For surfaces other than the top of an enclosure, either the sample could be supported on the side and subjected to the ball impact mentioned abov
43、e, or the steel sphere is to be suspended by a cord and swung as a pendulum, dropping through a vertical distance of 51 inches (1.29 m) to strike the surface with a 5 ft-lb. (6.78 joules) impact.
