21、.1 This standard states basic construction, test, and marking requirements for xture wires. Fixture wires are single conductor and are of the following types: 600 volt Types: PTF, PTFF, PAF, PAFF, KF-2, KFF-2, PF, PFF, PGF, PGFF, SF-2, SFF-2, ZF, ZFF, ZHF, TF, TFF, TFN, TFFN, RFH-2, FFH-2, RFHH-2, a
22、nd RFHH-3 300 volt Types: KF-1, KFF-1, SF-1, SFF-1, XF, and XFF These types are for use as specied in Article 402 and other applicable parts of the National Electrical Code (NEC), ANSI / NFPA 70. These types are as described individually in index Tables 4.1 4.9 of this standard. 1.1 revised June 7,
23、2005 2 Units of Measurement 2.1 In addition to being stated in inch/pound units, each numerical requirement in this standard is also stated in units that make the requirement conveniently usable in the various metric systems (practical SI and customary). Equivalent although not necessarily exactly i
24、dentical results are to be expected from applying a requirement in inch/pound or metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms. 3 References 3.1 Whenever the designation “UL 1581” is used in this wire standard, reference is to be made
25、to the designated part(s) of the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581. 4 Index Tables 4.1 Tables 4.1 4.8 each serve as an index to the requirements for construction details, test performance, and marking of the wire types described in the particular table. Eac
26、h vertical column summarizes and references the requirements that apply to the particular wire whose type letters appear at the top of the column.
