600 volt Types:
300 volt Types:
PTF, PTFF, PAF,PAFF, KF-2, KFF-2, PF, PFF, PGF, PGFF, SF-2, SFF-2, ZF, ZFF,ZHF.TF.TFFTFN,TFFN，RFH-2,FFH-2,RFHH-2,and RFHH-3
KF-1 KFF-1,SF-1, SFF-1, XF, and XFF

2 Units of Measurement
2.1 in addition to being stated in inch/pound units, each numerical requirement in this standard is alsostated in units that make the requirement conveniently usable in the various metric systems (practical Sand customary). Equivalent – although not necessarily exactly identical – results are to be expected fromapplying a requirement in inch/pound or metric terms. Equipment calibrated in metric units is to be usedwhen a requirement is applied in metric terms.
