5.1 This test method is intended to provide the user with acceptable apparatus requirements and a prescribed procedure to determine the bending moment capacity of spun pre-stressed concrete bases for use with tapered steel poles.
5.2 The results of this test method are used as a basis for verification of calculated bending moment capacity, quality control tool for manufacturing process and as a basis for determining statistical bending moment capacity.
5.3 This test method shall not be used for full length prestressed concrete, steel, or composite poles.
Область применения1.1 This test method covers determination of ultimate bending moment capacity and cracking moment capacity of concrete bases used as foundations for tapered steel lighting poles in accordance to Specification C1804.
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 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.
1.4 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.
