1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ( 3 / 4 hard), 1350-H14 or -H24 ( 1 / 2 hard), and 1350-H142 or -H242 ( 1 / 2 hard), bare concentric-lay-stranded conductors constructed with a straight round central wire surrounded by one or more layers of helically layed wires. The conductors are for general use for electrical purposes (Explanatory Note 1 and Note 2 ).

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.

Note 1 Prior to 1975, aluminum 1350 was designated as EC aluminum.
Note 2 The aluminum and temper designations conform to ANSI Standard H35.1/H35.1M . Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527 .
Note 3 Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification.
