16、 REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 This standard covers adhesive and non-adhesive backed tapes intended for use with nished electro-mechanical products. 1.2 Results obtained provide data with respect to the physical, electrical, ammability, thermal, adh

17、esion and other properties of the tapes under consideration and are intended to provide guidance for tape manufacturers, end-product manufacturers, safety engineers, and other interested parties. 1.3 This standard also covers tapes which have only been subjected to thickness and ammability tests in

18、accordance with Thickness, Section 9 and Flame Test, Section 20, respectively. Tapes subjected only to ammability tests in accordance with Section 20 may employ a conductive backing. 1.4 This standard does not cover adhesive coated polyvinyl chloride (PVC), adhesive coated polyethylene (PE) and rubb

19、er tapes intended for use on joints and splices in wires and cables in accordance with the National Electrical Code, NFPA 70 at not more than 80C (176F) and 600 V. These types of tapes are covered by the Standard for Polyvinyl, Polyethylene, and Rubber Insulating Tape, UL 510. 2 Units of Measurement

20、 2.1 Values stated without parentheses are the requirement in SI units, unless otherwise noted. Values in parentheses are explanatory or approximate information. 3 Referenced Publications 3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpre

21、ted as referring to the latest edition of that code or standard. 4 Use of Tapes 4.1 The safety of electrical equipment often depends upon the correct selection of tapes, design, as well as the assembly, mounting, and relative positions of these parts. 4.2 The properties needed by individual applicat

22、ions are dened by the function or functions of the tape. A tape used as interwinding insulation in a transformer, for example, must ordinarily be designed to withstand electrical stress at elevated use temperatures. Accordingly, a tape known to have suitable thermal endurance and substantial dielect

23、ric strength would normally be used although a material of lower dielectric strength used in multiple layers may also be satisfactory. 4.3 End products may employ many tapes that usually have divergent properties. The ability to match the demands of the application with the attributes of a tape as w

24、ell as the ability to compare the properties of one tape with those of another can lead to the selection of an acceptable tape.

25、 from the data obtained from these tests can be used as an aid in the evaluation of end products using tapes. Knowledge of a tapes performance can be obtained from an analysis of data from standard tests conducted on small specimens. 5 Tape Tests Based on Functional Use 5.1 According to the function

26、al uses in the end product, each tape shall comply with the tests specied in Table 5.1. See also 8.1.

36、e specied in the individual test method, the average of the results for the specimens tested shall be used to determine compliance with the requirements of this standard. 6.2 Unless otherwise specied in the individual test method, tensile strength and elongation results for specimens that break at s

37、ome obvious aw or that do not break between the predetermined bench marks shall be discarded. 7 Circulating Air-Oven 7.1 The apparatus for all the air-oven aging of specimens shall be in accordance with the Standard Specication for Forced-Convection Laboratory Ovens for Evaluation of Electrical Insu

38、lation, ASTM D5423, Type 2. The motor-operated fan or other means for circulating the air shall be located entirely outside the aging chamber. Unless otherwise specied, the oven shall maintain the specied temperature within 3C (5.4F). ALL TAPES 8 General 8.1 The requirements in Sections912apply to a

39、ll electrical insulating tapes covered in this standard and are supplemented by additional requirements in Sections 13 22 in accordance with the functional uses in the end product (see Table 5.1 for guidance). Exception: Tapes may be evaluated only for ammability property in accordance with Thicknes

40、s, Section 9 and Flame Test, Section 20. 8.2 Unlessotherwisespecied,lengthsof25-mm(1-in)widetapeforuseasspecimensinanyofthetests specied in this standard shall 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

41、 other extraneous motion whenever the tape is unrolled. The tape shall be in thermal equilibrium with the surrounding air at a temperature of 23 5C (73.4 9F) whenever being unrolled. The tape shall always be unrolled at an even rate of approximately 50 mm/s or (2 in/s). The rst three layers of tape

42、shall be discarded. Each length of tape intended as a specimen, or from which a specimen is prepared, shall be protected from dust and direct handling of the adhesive and shall be placed adhesive side up on a smooth, clean surface or shall be suspended in air for a minimum of 1 h after removal from

43、a roll and before being used in a test. MAY 3, 2017 COMPONENT TAPES - UL 510A 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Exception: Lengths of tape for use as adhesion test specimens shall be placed adhesive side up on a smooth, clean

44、surface or shall be suspended in air for a minimum time corresponding to the conditions specied in 15.1. 8.3 Unless otherwise specied, all testing, except for ammability, shall be conducted at 23 5C (73.4 9F) and a relative humidity of 50 10%. Flammability testing shall be conducted in still air at

45、a temperature of 15 35C (59 95F) and a relative humidity of 75%. All samples shall be preconditioned at 23 5C (73 9F) and a relative humidity of 50 10% for a minimum of 30 min prior to test. 8.4 Unless otherwise indicated for a specic test, testing of each construction in the un-pigmented and heavie

46、st pigmented dark and light tapes (such as black and white) are considered to represent the range of colors for each test. If the tape is produced with the pigment in different layers, such as the backing, reinforcement and/or adhesive, each of those unique constructions will also require the basic

47、tests in Sections912andanyother test chosen. Each tape shall be considered a unique construction with its own catalog number and tested accordingly if the grade or designation and/or manufacturer of any individual layer changes. A tape is also considered a unique construction if the thickness of any

48、 individual layer varies by more than 10%. 8.5 Tape shall be made and nished with the degree of uniformity and quality of work that are practical in a well-equipped factory. Only materials qualied as acceptable for the manufacture of the tape complying with the requirements of this standard shall be

49、 used. 9 Thickness 9.1 All tapes 9.1.1 The average thickness for each tape and each individual layer of a composite tape shall be determined in accordance with 9.2, 9.3, or 9.4 as appropriate. 9.1.2 Each individual layer shall be supplied separately, where practical, with the exception of the adhesive whose thickness shall be obtained by subtracting the average thickness of all non-adhesive layers, resulting in the adhesive thickness. 9.1.3 The average
