    Abstract

    This specification covers bare concentric-lay-stranded conductors made from bare round copper-clad steel wires for general use for electrical purposes. Conductors are classified as follows: Grade 40 HS, Grade 30 HS, and Grade 30 EHS. The numbers and diameters of the wires in the concentric-lay-stranded conductors shall conform to the requirements prescribed. Tests for physical and electrical properties of wires composing concentric-lay-stranded conductors made from copper-clad steel wire shall be made before stranding.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers bare concentric-lay-stranded conductors made from bare round copper-clad steel wires for general use for electrical purposes.

    1.2 For the purpose of this specification, conductors are classified as follows: Grade 40 HS, Grade 30 HS, Grade 30 EHS, Grade 40 DSA, and Grade 30 DSA.

    The grades covered by this specification correspond to the following commercial designations:

    Grade 40 HS,

    High Strength, 40 % Conductivity, Hard Drawn

    Grade 30 HS,

    High Strength, 30 % Conductivity, Hard Drawn

    Grade 30 EHS,

    Extra High Strength, 30 % Conductivity, Hard Drawn

    Grade 40 DSA,

    40 % Conductivity, Dead Soft Annealed

    Grade 30 DSA,

    30 % Conductivity, Dead Soft Annealed

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
