ANSI UL 62:2000 pdf free download – Flexible Cord and Fixture Wire
1.1 These requirements cover fixture wires, hoistway cables, and flexible cords for use in accordance with the National Electrical Code.
1.2 An elevator cable that contains one or more optical-fiber 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 flexible cords or fixture wires with fttings or wiring devices of any sort (such as cord sets, power-supply cords, and Christmas-tree and decorative-lighting outfits, 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-fiber member 0 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 fire, 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 conflict with specific 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
2.1In 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
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 A fixture wire is a single conductor, whereas hoistway cable and flexible cord are assemblies of two or more conductors. Fixture wire has a solid conductor or either a 7-strand construction or a flexible stranding, whereas a flexible cord always has flexible stranding. Aside from the metal conductor itself, however, the requirements for fixture wire are essentially the same as for flexible cord.
3.3 It is to be noted that a flexible conductor is always stranded but that a stranded conductor is not necessarily flexible – for example, a 7-strand fixture wire is not a flexible conductor when compared with a wire having a larger number of finer strands.
