Abstract
This standard specifies the test methods for tensile, bending, repeated bending, torsion, winding, isothermal relaxation, fatigue, stress corrosion, skewed tensile, chemical analysis, geometric dimension measurement, and determination of relative rib area for steel used in prestressed concrete. This standard is applicable to the determination of the relevant performance of products such as prestressed steel wires, steel rods, and steel strands.
