(Specification)Standard Specification for Spun Cast Prestressed Concrete Poles
Standard Specification for Spun Cast Prestressed Concrete Poles
ABSTRACT
This specification covers spun cast prestressed concrete poles for use as structural supports for streetlights, traffic signals, and transmission, distribution, and communication lines. The acceptability of the poles shall be determined by the results of full-scale bending and torsional tests. The requirements for the following are specified: (1) materials such as cement, aggregate, water, chemical admixtures, steel, and inserts; (2) general requirements including concrete cover, circumferential wire, grounding, exterior surface treatment, and prestressing; and (3) loading requirements. Load test procedures for bending and torsional tests are detailed. Sets of fabrication and detail drawings shall be furnished as prescribed in this specification.
SCOPE
1.1 This specification covers spun cast prestressed concrete poles for use as structural supports for electric transmission, distribution, and communication lines; streetlights; and traffic signals.
1.2 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.
1.3 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
