UNE 36094:1997 specifies the requirements for high-strength steel wire and strand used as active reinforcement in prestressed concrete. It covers smooth and indented wire, as well as two-wire, three-wire, and seven-wire strand.
The standard defines steel types, product designations, manufacturing requirements, geometric and mechanical properties, testing methods, supply and storage conditions, and conformity assessment procedures. It includes requirements for tensile strength, elastic limits, elongation, relaxation, fatigue, stress corrosion, chemical composition, and dimensional characteristics.
This 22-page PDF also includes dimensional and property tables for wire and strand, additional performance requirements, sampling procedures, inspection criteria, and acceptance coefficients.
Application Scope: Applicable to steel wire and strand for prestressed concrete reinforcement, concrete pipes, ground anchors, bridge suspension systems, and bridge stays.
