ANSI UL 62:2000 pdf download Flexible Cord and Fixture Wire
1.1 These requirements cover xture wires, hoistway cables, and exible cords for use in accordance with the National Electrical Code.
1.2 An elevator cable that contains one or more optical-ber members is limited (see 8.6) to carrying optical energy that has been ruled not hazardous to the human body.
1.3 These requirements do not cover armored cords or assemblies of exible cords or xture wires with ttings or wiring devices of any sort (such as cord sets, power-supply cords, and Christmas-tree and decorative-lighting outts, which are covered in requirements separate from this standard) nor do these requirements cover any type of wire or cord for use at a potential higher than 600 V.
1.4 These requirements do not cover the optical or other performance of any optical-ber member or group of such members. See 8.6.
1.5 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of re, electric shock, or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conict with specic requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 Units of Measurement Section

2.1 In addition to being stated in the inch/pound units that are customary in the USA, each of the requirements in this Standard is also stated in units that make the requirement conveniently usable in countries employing the various metric systems (practical SI and customary). Equivalent– although not necessarily exactly identical – results are to be expected from applying a requirement in USA or metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms.

3.1 Wherever the designation ″UL 1581″ is used in this wire Standard, reference is to be made to the designated part(s) of the Reference Standard for Electrical Wires, Cables, and Flexible Cords (UL 1581).
3.2 Axture wire is a single conductor, whereas hoistway cable and exible cord are assemblies of two or more conductors. Fixture wire has a solid conductor or either a 7-strand construction or a exible stranding, whereas a exible cord always has exible stranding. Aside from the metal conductor itself, however, the requirements for xture wire are essentially the same as for exible cord.
3.3 It is to be noted that a exible conductor is always stranded but that a stranded conductor is not necessarily exible – for example, a 7-strand xture wire is not a exible conductor when compared with a wire having a larger number of ner strands.
