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 streetlights; traffic signals; transmission, distribution, and communication lines.
1.2 The values stated in in-pound units are to be regarded as the standard. The values given in parentheses are for information only.
WITHDRAWN RATIONALE
This specification covers spun cast prestressed concrete poles for use as structural supports for streetlights; traffic signals; and transmission, distribution, and communication lines.
Formerly under the jurisdiction of Committee C27 on Precast Concrete Products, this specification was withdrawn in March 2006 in accordance with section 10.5.3.1 of the  Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
