ISO 6934-1 Hydraulic Universal Testing Machine for Steel Strand Tensile Test
I. Test Objectives
Determination of Mechanical Properties:
Through the tensile test, accurately obtain the mechanical property parameters of steel strands, including tensile strength (ultimate strength under maximum load), yield strength (stress at 0.2% plastic deformation), and elongation after fracture (extension capacity of the gauge section after fracture), providing quantitative data for material mechanical property analysis.
Verification of Engineering Applicability:
Compare the test results with design specifications or relevant standards to determine whether the steel strands meet the safety and reliability requirements for practical application scenarios such as bridges, building structures, and prestressed engineering, ensuring the stability of engineering structures.
2. Test Standards
GB/T 5224-2014 Steel Strands for Prestressed Concrete
Scope of Application:
Specifically for steel strands used in prestressed concrete, it specifies the specific methods, performance indicators, and acceptance rules for tensile tests, serving as the core standard for the production and inspection of prestressed steel strands.
GB/T 228.1-2021 Metallic Materials—Tensile Testing—Part 1: Method of Test at Room Temperature
General Basic Standard: Applicable to tensile tests of various metallic materials at room temperature, specifying general methods for test equipment, sample preparation, test procedures, and data processing, providing basic operation specifications for steel strand tensile tests.
ASTM A416/A416M-21 Standard Specification for Steel Strands for Prestressed Concrete
American Standard: Mainly used to standardize the technical requirements for steel strands in prestressed concrete, including tensile performance indicators, test methods, and acceptance criteria, widely applied in international engineering fields (especially in North America).
ISO 6934-1:Steel for the Reinforcement of Concrete—Part 1: Strands
ISO Standard: Specifies the mechanical properties, test methods, etc., of steel strands for concrete structures, providing a unified reference for the production and inspection of steel strands worldwide.
