23、ing requirements for fixture wires. Fixture wiresare 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, and RFHH-3300 volt Types: KF-1, KFF-1, SF-1, SFF-1, XF, and
24、XFFThese types are for use as specified in Article 402 and other applicable parts of the National ElectricalCode (NEC), ANSI / NFPA 70. These types are as described individually in index Tables 4.1 4.9 of thisstandard.1.1 revised June 7, 20052 Units of Measurement2.1 In addition to being stated in i
25、nch/pound units, each numerical requirement in this standard is alsostated in units that make the requirement conveniently usable in the various metric systems (practical SIand customary). Equivalent although not necessarily exactly identical results are to be expected fromapplying a requirement in
26、inch/pound or metric terms. Equipment calibrated in metric units is to be usedwhen a requirement is applied in metric terms.3 References3.1 Whenever the designation “UL 1581” is used in this wire standard, reference is to be made to thedesignated part(s) of the Reference Standard for Electrical Wire
27、s, Cables, and Flexible Cords, UL 1581.4 Index Tables4.1 Tables 4.1 4.8 each serve as an index to the requirements for construction details, testperformance, and marking of the wire types described in the particular table. Each vertical columnsummarizes and references the requirements that apply to
28、the particular wire whose type letters appearat the top of the column. The applicable paragraphs and tables in this standard (UL 66) are indicated inparenthesis.
