27、RODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover Appliance Wiring Material (AWM) in the form of single insulated conductors, multi-conductor cables, optical bers, individual insulated conductors, and ber optic members for use as components in mul

28、ti-conductor cables. 1.2 The appliance wiring material covered by the requirements of this Standard are solely for use as factory-installed wiring either within the overall enclosure of appliances and other equipment (internal wiring) or as external interconnecting cable for appliances (external wir

29、ing), or for further processing as components in multi-conductor cables. 1.3 These requirements do not cover any wire, cable, or cord types that are presently covered in the National Electrical Code (NEC), NFPA 70, and are not intended for installation in buildings or structures in accordance with t

30、he NEC except within the scope of the installation instructions of the end-product for which their use is intended. 1.4 These requirements cover appliance wiring material with operating temperatures from a minimum 60C (140F) dry temperature rating and voltage ratings from a minimum 30-volt rating. C

31、onductor size ranges from 50 AWG to 2000 kcmil. Appliance wiring material (AWM) composed entirely of optical ber members or electrical conductors in combination with optical ber members are also covered by these requirements. 1.5 These requirements do not cover the optical performance of any optical

32、-ber member or group of such members. 1.6 These requirements do not cover constructions which utilize at, insulated conductors that are not laid parallel. The requirements for these products are found in the Standard for Flexible Materials Interconnect Constructions, UL 796F. 1.7 The evaluation of t

33、he performance of the semi-conductive polymeric layer described in 5.9 is not covered by this Standard. 1.7 effective September 3, 2014 1.8 In addition to these constructions, this Standard establishes guidelines for the evaluation of special constructions that, due to their specic end product use,

34、are not required to meet all of the requirements for general construction AWM. 1.9 The nal acceptance of AWM is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment.

36、equirement 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 standard. 2.1.3 A component shall be used in accordance with its rating established for the intended conditi

37、ons of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

38、2.1.5 Polymeric materials evaluated for its intended use, are not prohibited from being used in the insulation and jacket applications indicated in Table 2.1.

42、 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2.2 Unless otherwise indicated, all voltage values mentioned in this Standard are root-mean-square (rms). 2.2.3 Equipment calibrated in metric units is to be used when a requir

43、ement is applied in metric terms. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.3.2 Wherever the designation UL 1581 is used in this Standard,

44、 reference is to be made to the designated part(s) of the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581. Wherever the designation UL 62 is used in this Standard, reference is to be made to the designated part(s) of the Standard for Flexible Cords and Cables, UL 62. CON

45、STRUCTION 3 General 3.1 The acceptability of an AWM for use in a specic end-product is based on the construction and ame rating of each individual construction. 3.2 Tables 3.1 3.9 serve as indices to requirements for construction details and basic test methods for typical AWM constructions. 3.3 Coil

46、ed cables shall comply with the requirements specied in this Standard. All tests and measurements shall be conducted on specimens obtained from the straight ends at each end of the coiled portion of the cable. The straight ends shall have been subjected to the same heat conditioning as the coiled po

47、rtion during the coiling process. In addition, the minimum average thickness and minimum thickness at any point of insulation and jacket shall be made on the coiled portion and shall meet the requirements specied for an uncoiled construction. 3.4 Wires or cables which have a restricted use are those

48、 installed where not subject to movement or mechanical abuse, or where totally enclosed. 3.5 A wire or cable for Class 2 use shall have a voltage rating less than or equal to 150 V AC or DC. 3.5 effective September 3, 2014 3.6 The high voltage DC wire described in Table 3.6 shall have a minimum volt

49、age rating of 3 kV DC. Wires with DC voltage rating less than 3 kV DC shall be evaluated in accordance with Table 3.1.
