    1.1 This standard states basic construction, test, and marking requirements for fixture 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, and RFHH-3

      300 volt Types:

    KF-1, KFF-1, SF-1, SFF-1, XF, and XFF

    These types are for use as specified 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.
