Organization: | ASTM International |

Status: | inactive |
Page Count: | 5 |
ICS Code (Steels for reinforcement of concrete): | 77.140.15 |
scope:
1.1 This specification covers two types and two grades of seven-wire, uncoated steel strand for use prestressed concrete construction. The two types of strand are low-relaxation and stress-relieved (normal-relaxation).
1.2 A supplementary requirement (S1) is provided for use where bond strength testing of 0.600-in. [15.24-mm] diameter Grade 270 [1860] strand for applications in prestressed ground anchors is required by the purchaser. The supplementary requirement applies only when specified in the purchase order.
1.3 This specification is applicable for orders in either inch-pound units (as Specification A416) or in SI units (as specification A416M).
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.
