ASTM F1883-03(2013)
(Practice)Standard Practice for Selection of Wire and Cable Size in AWG or Metric Units
Standard Practice for Selection of Wire and Cable Size in AWG or Metric Units
SIGNIFICANCE AND USE
3.1 The selection criteria is to be applied for uses of (1) new cable and (2) replacement cable.
3.2 For the selection of new cable or the selection of replacement cable, this practice defines the choice criteria for conductor selection for cables in AWG (ASTM) or metric (IEC) sizes.
SCOPE
1.1 This practice is intended as a guide to shipbuilders, shipowners, and design agents for use in the selection of conductor size for single conductor or multiple conductor cable sizes either in American Wire Gauge (AWG) or metric designations for commercial ship design and construction.
1.2 The comparison chart of electrical conductor sizes shown in Table 1 presents a combined listing of international standard sizes of Class 2 stranded copper conductors in accordance with AWG (Specification B8) English units or IEC (IEC 60228) metric units.TABLE 1 Conversion Table—AWG/Metric Preferred Sizes of Conductors
