ASTM B324-01(2016)

Standard Specification for Aluminum Rectangular and Square Wire for Electrical Purposes

ABSTRACT
This specification covers aluminum 1350-O, annealed, 1350-H12 or -H22, 1350-H14, 1350-H16 or -H26, and 1350-H19 wire, rectangular or square in shape with round corners for use as electrical conductors in insulated magnet wire. The aluminum wire shall be made from rod in accordance with the requirements specified. Tensile strength test, low stress elongation test, bending test, and electrical resistivity test shall be made to conform to the specified requirements.
SCOPE
1.1 This specification covers aluminum 1350-O, annealed, 1350-H12 or -H22 (1/4 hard), 1350-H14 or -H24 (1/2 hard), 1350-H16 or -H26 (3/4 hard), and 1350-H19 (extra hard) wire, rectangular or square in shape with rounded corners for use as electrical conductors in insulated magnet wire.  
1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be used independently of the other. Combining the values from the two systems may result in non-conformance with the specification. For conductor sizes designated by AWG or kcmil sizes, the requirements in SI units are numerically converted from the corresponding requirements in inch-pound units. For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. for conductor sizes designated by SI units only, the requirements are stated or derived in SI units.  
1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
Note 1: The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.
