Standard Specification for Spun Cast Prestressed Concrete Poles (Withdrawn 2006)

SCOPE
1.1 This specification covers spun cast prestressed concrete poles for use as structural supports for street lights; traffic signals; transmission, distribution, and communication lines.
WITHDRAWN RATIONALE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Formerly under the jurisdiction of Committee C27 on Precast Concrete Products, this specification was withdrawn in March 2006 in accordance with section 10.5.3.1 of the  Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
