20、lastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80C (176F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code ANSI/NFPA 70. It is intended that rubber tape on a joint or splice be mechanically protec
21、ted by a covering such as friction tape. Thermoplastic tape is acceptable without the additional mechanical protection. 1.2 The characteristic constituent of the thermoplastic tape covered in this Standard is either PVC (polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate), or PE (
22、thermoplastic polyethylene). For the characteristic constituent(s) of rubber tape, see 18.1. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering component
23、s used in the products covered by this standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this st
24、andard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as cer
25、tain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 3 Units of Measurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. FEBRUARY 10, 2005 POLYVINYL CHLORIDE, POLYETHYLENE

30、pecimens in any of the tests specied in this Standard are to be taken from sample rolls of nished tape tted snugly onto a horizontal rod or tube that is free to turn in its supports without wobbling or other extraneous motion whenever the tape is unrolled. The tape is to be in thermal equilibrium wi
31、th the surrounding air at a temperature of 23.0 5.0C (73.4 9F) whenever being unrolled. The tape is always to be unrolled at an even rate of approximately 2 in/s (50 mm/s) that is, rather slowly. The rst three layers of tape are to be discarded. Each length of tape intended as a specimen or from whi
32、ch a specimen is prepared is to be protected from dust and is to be placed adhesive side up on a smooth, clean surface or is to be suspended in air for 1 hour under the conditions specied in 5.3 after removal from a roll and before being used in a test. 5.3 Unless otherwise specied, all testing shal
33、l be conducted in still air at a temperature of 23.0 5.0C (73.4 9F) and a relative humidity of 50 10 percent.

34、UL 6 Flame Test 6.1 Insulating tape marked ame retardant in accordance with 24.2 shall not ame longer than 60 seconds following any of ve 15 seconds applications of the test ame, the period between applications being: a) 15 seconds if the specimen aming ceases within 15 seconds; or b) The duration o
35、f the specimen aming if the specimen aming persists longer than 15 seconds. The tape shall not ignite combustible materials in its vicinity or damage more than 25 percent of the indicator ag during, between, or after the ve applications of the test ame. The test is to be conducted as described in 6.
36、2 6.10. 6.1.1 The testing of the 3/4 in (19 mm) specimen width is considered representative of the performance of all sizes (widths) of the tape. 6.1.1 added April 30, 2008 6.2 The test specimen is to be prepared as follows. A straight clean steel rod 18 in (460 mm) long and 1/8 in (3.2 mm) in diame
37、ter is to be supported in a winding jig. The winding jig is to support the rod at each end and have a crank for rotating the rod so that the tape can be wound thereon. The winding jig is to be attached to a rigid support in such a manner that it can be rotated, tilting the major axis of the rod to t
38、he horizontal. A 3-ft (900-mm) length of 3/4 in (19 mm) tape is to be cut from a roll. The tape sample is to be secured, by overlapping the rst turn of tape, to the rod held in a horizontal position. A weight exerting 4.4 lbf, 19.6 N, or 2.0 kgf is then to be attached to the free end of the 3 ft (90
39、0 mm) sample to provide tension. After 1 minute under tension, the rod is to be slowly rotated, and the xture tilted so that the tape wraps with an overlap equal to one half the width of the tape. After wrapping is completed, the lower end of the tape is to be secured and the remaining length of tap
40、e is to be cut off. A second wrapping is to be similarly applied with the direction of advance of the turns of the tape reversed from that of the rst wrapping. Finally, a third wrapping of tape is to be similarly applied with the direction of advance opposite to that of the second wrapping. Thus, si
41、x thicknesses of tape are to result at each point along the wrapped mandrel. 6.2.1 A strip of unreinforced 60-lb (94-g/m 2 ) kraft paper that is 1/2 in (13 mm) wide, approximately 5 mils (0.1 mm) thick, and is gummed on one side is to be used to make an indicator ag. The gumming is to be moistened b
42、ut not more than necessary to facilitate adhesion. With the gum toward the specimen, the strip is to be wrapped around the specimen once with its lower edge 10 in (254 mm) above B, the point at which the blue inner cone is to touch the specimen. The ends of the strip are to be pasted together evenly
43、 and trimmed to provide a ag that projects 3/4 in (19 mm) from the specimen toward the rear of the enclosure with the ag parallel to the sides of the enclosure (see Figure 6.1). The lower clamp or other support for the specimen is to be adjusted vertically to keep it from being any closer than 3 in
44、(76 mm) to point B. 6.7 relocated as 6.2.1 April 30, 2008 6.3 The test is to be conducted in a 3-sided metal enclosure positioned inside of a fume hood or cabinet. The 3-sided metal enclosure is to be 12 in (305 mm) wide, 14 in (355 mm) deep, 24 in (610 mm) high, and the top and front are to be open
45、. The test specimen detailed in 6.2 is to be secured with its longitudinal axis vertical in the center of the enclosure.

46、THER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL cotton 1/4 to 1 in (6 to 25 mm) thick is to cover the oor of the enclosure. The upper surface of the cotton is to be 9 to 9-1/2 in (229 to 241 mm) below point B, which is the point at which the tip of the blue inner cone of the test ame to
47、uches the specimen. This is shown in Figure 6.1. 6.3 revised April 30, 2008 6.3.1 The fume hood or cabinet is to be a draft-free chamber having an air-tight, windowed sash, door, or other means for access and viewing. Each linear interior dimension of the chamber is to be at least 24 inches or 610 m
48、m. The actual dimensions are to result in an interior volume of the chamber of at least 140 ft 3 o r4m 3 , including the volume of the exhaust transition. The size of the exhaust transition, if any, is not specied. At least 70 ft 3 o r2m 3 of this volume is to be above the area of the gas and specim

The chamber volume at or below the level of the ames is not to contain obstructions to the natural ow of chamber air supplying oxygen to the ames. 6.3.1 added April 30, 2008 6.3.2 The chamber is to have an air-tight glove box for arm-and-hand access to the apparatus or other means for adjusting the apparatus while the access is completely closed. The interior of the chamber is
