27、ory-installed wiring either within the overall enclosure of appliances and other equipment (internal wiring) or as external interconnecting cable for appliances (external wiring), or for further processing as components in multi-conductor cables. 1.3 These requirements do not cover any wire, cable,
28、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 the NEC except within the scope of the installation instructions of the end-product for which their use is intended. 1.4 These
29、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. Conductor size ranges from 50 AWG to 2000 kcmil. Appliance wiring material (AWM) composed entirely of optical ber members or el
30、ectrical 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-ber member or group of such members. 1.6 These requirements do not cover constructions which utilize at, insulated conductors
31、 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 the performance of the semi-conductive polymeric layer described in 5.9 is not covered by this Standard. 1.7 effective Septembe
32、r 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, are not required to meet all of the requirements for general construction AWM. 1.9 The nal acceptance of AWM is dependent upon
33、 its use in complete equipment that conforms with the standards applicable to such equipment.
