Description of ASTM-F1883 2013ASTM F1883-03-Reapproved2013Historical Standard: Standard Practice for Selection of Wire and Cable Size in AWG or Metric UnitsASTM F1883Scope 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
A Ampacity of single-conductor cable in air at ambient temperature of 30°C and maximum conductor temperature not exceeding 60°C.
B Temperature correction: the conductor resistance may be corrected for moderate temperature differences from the noted reference temperature by the following equation. The
parameter, αT, varies with conductivity and temperature. For a list of common temperature coefficients see Test Methods B193.
C An asterisk (*) indicates preferred sizes for wires of American Wire Gauge or per IEC 60228 (metric) as appropriate.
1.3 As a precautionary caveat, some conductor sizes listed in Table 1 may exceed minimal size requirements of the U.S. Coast Guard, the American Bureau of Shipping, and IEEE STD 45 for specific applications. 1.4 The values stated for ampacity and dc resistance are presented as maximum values and are provided for information only.
