|ICS Code (Steel wire, wire ropes and link chains):||77.140.65|
1.1 This specification covers ASTM Specification A 416 low-relaxation Grade 250 and Grade 270 seven-wire prestressing steel strand with protective fusion-bonded epoxy coating applied by the electrostatic deposition method or other method that will meet the coating requirements in Section 7.
Note 1-The manufacturer as identified throughout this specification is the coating applicator.
1.2 Supplementary Requirements S1 contains requirements for epoxy-coated and filled strand. Epoxy-coated and filled strand shall not be furnished unless ordered, or by arrangement between purchaser and manufacturer.
Note 2-This standard is a product specification and it does not delineate requirements regarding the use of epoxy-coated strand. Proper use of epoxy-coated strand includes design considerations, handling, installing, and stressing of strands, permissible concrete curing temperature, and procedures for repairing damaged coating and protection of the ends of strands. Information and procedures for such items are presented in a report by the PCI Ad Hoc Committee on Epoxy-Coated Strand.
1.3 This specification is applicable for orders in either inch-pound units (as Specification A 882) or SI units [as Specification A 882M].
1.4 The values stated in either inch-pound or SI units are to be regarded as standard. Within the test, the SI units are shown in brackets. The values stated in each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
