34、r defects that increase the risk of re, electric shock, or injury to persons. 7.2 A polymeric material used to enclose or provide structural support for electrical current carrying parts shall: a) Have a minimum ammability rating of V-0; and b) Have a minimum HWI (hot-wire resistance to ignition) Pe
35、rformance Level Category (PLC) of 3, a minimum HAI (high-current arc resistance to ignition) PLC of 3, and a minimum CTI PLC of 4, if marked for indoor use, or a minimum PLC of 3, if marked for outdoor use. Exception No. 1: The minimum ame rating shall be HB when the exible lighting product is locat
36、ed in a Class 2 circuit. Exception No. 2: A exible lighting product whose enclosure is extruded of an insulation compound that is rated 105C, and also complies with the requirements of the VW-1 ame test, and 720 hour weatherometer test, need not comply with 7.2(a) and (b) when the ropelight body com
37、plies with the VW-1 ame test as described in the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581, and when intended for outdoor use, complies with the VW-1 ame test and crush test after being subjected to the Ultraviolet (UV) Light Exposure and Water Immersion Tests desc

41、ISSION FROM UL 7.6 The ammability rating specied in 7.2(a) is to be determined by the applicable tests in the Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances, UL 94. 7.7 As an alternative to 7.2(a), the polymeric material is able to comply with the 3/4 in
42、ch or 12 mm ame test of the Standard for Polymeric Materials Use in Electrical Equipment Evaluations, UL 746C. At the conclusion of the test there shall not be openings large enough to enable a 1/4 inch (6.4 mm) diameter rod to penetrate the enclosure and there shall not be ignition of the cotton in
43、dicator. The indicator is to be absorbent, 100 percent cotton thinned to approximately 2 by 2 inches (50 by 50 mm) and a maximum thickness of 0.24 inches (6 mm). The cotton is to be placed horizontally 11.8 0.39 inches (300 10 mm) below the component material. 7.8 With regard to consideration of the
44、rmal endurance in the Standard for Polymeric Materials Use in Electrical Equipment Evaluations, UL 746C, the material shall possess a mechanical temperature index, with impact, as a result of long term aging or a generic temperature index of at least the measured temperature in the Normal Temperatur
45、e Test, Section 26. 7.9 The temperature index specied in 7.8 shall include temperatures measured on polymeric materials closest to or in direct contact with any lamp. 7.10 An enclosure formed of polymeric material and marked for outdoor use in accordance with Section 48, Outdoor Use Markings, shall

47、polymeric material may be employed as an enclosure of a exible lighting product marked for outdoor use provided it complies with the ammability rating evaluation of 7.6 or 7.7 as applicable, the Crush Test, Section 30, and the Ball Impact Test, Section 32, after being subjected to the Ultraviolet (U
48、V) Light Exposure and Water Immersion Tests described in Section 31. The end-product test force and impact values shall be reduced by 30 percent after the UV light exposure test, and reduced by 50 percent after the water immersion test. At the conclusion of the conditioning and end-product tests, th
49、e ammability rating shall not be reduced and the samples shall comply with the requirements of 30.3 and 32.6. The ball impact test is only applicable to a controller or other accessory used with a exible light. 7.12 If a exible light enclosure consists of multiple layers of polymeric materials, all layers shall comply with 7.2 and only the outermost layer needs to comply with the UV resistance and water exposure requirements of 7.10(a), providing that the material used for the outermo
