Various organizations and bodies, such as the International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN), set the international standards for steel rebars.
ISO establishes standards for steel rebars through ISO 15630, which covers both hot-rolled and cold-worked rebars. This standard outlines the requirements for the chemical composition, mechanical properties, dimensions, and tolerances of rebars used in reinforced concrete structures.
ASTM has developed multiple standards for steel rebars, such as ASTM A615/A615M and ASTM A706/A706M. ASTM A615/A615M focuses on deformed and plain carbon-steel rebars for concrete reinforcement, specifying the chemical composition, mechanical properties, dimensions, and marking requirements. On the other hand, ASTM A706/A706M concentrates on low-alloy steel rebars with improved weldability, suitable for concrete structures that require welding.
In Europe, CEN has established the primary standard for steel rebars as the Eurocode 2 (EN 1992-1-1). This code provides design rules for the structural use of concrete and includes guidelines for the selection and utilization of rebars. Additionally, CEN has also developed EN 10080, which specifies the requirements for steel rebars used in concrete reinforcement, covering chemical composition, mechanical properties, dimensions, and tolerances.
These international standards guarantee the quality and consistency of steel rebars utilized in construction projects worldwide. Complying with these standards helps ensure the safety and reliability of reinforced concrete structures by providing guidelines for material properties, manufacturing processes, and quality control measures.

ISO provides standards for steel rebars under ISO 15630, which covers both hot-rolled and cold-worked rebars. This standard defines the requirements for the chemical composition, mechanical properties, dimensions, and tolerances of rebars used in reinforced concrete structures.
ASTM has developed several standards for steel rebars, including ASTM A615/A615M and ASTM A706/A706M. ASTM A615/A615M covers deformed and plain carbon-steel rebars for concrete reinforcement, specifying the chemical composition, mechanical properties, dimensions, and marking requirements.
