Full title and description

Steel for the reinforcement and prestressing of concrete — Test methods — Part 1: Reinforcing bars, rods and wire. This International Standard specifies chemical and mechanical test methods and measurement methods of geometrical characteristics applicable to reinforcing bars, rods and wire used for concrete reinforcement and prestressing applications.

Abstract

ISO 15630-1:2019 defines standardised laboratory procedures for determining mechanical properties (tensile strength, elongation, proof forces), ductility (bend and rebend tests), fatigue behaviour (axial force fatigue), chemical composition, and geometrical characteristics (rib/indentation geometry, relative rib/indentation area, mass per metre) of reinforcing steel in the form of bars, rods and wire. Annex A provides options for agreement between supplier, purchaser and laboratory.

Scope

Specifies chemical and mechanical test methods and measurement procedures of geometrical characteristics applicable to reinforcing bars, rods and wire for concrete. It does not cover sampling conditions (these are addressed in product standards). The standard includes routine and specialised tests (e.g., tensile tests at elevated or low temperature, cyclic inelastic load tests) and provides an informative Annex of options for agreement between the parties.

Key topics and requirements

• Tensile tests at ambient temperature (specimen selection, equipment, procedure, interpretation of tensile strength, elongation and proof forces).
• Bend and rebend tests to assess ductility and bending performance (including equipment and acceptance criteria).
• Axial force fatigue testing for endurance assessment under cyclic axial loading.
• Chemical analysis procedures to verify steel composition against product requirements.
• Measurement of geometrical characteristics and rib/indentation metrics (rib heights, spacing, pitch, angles) and calculation methods for relative rib/indentation area.
• Determination of deviation from nominal mass per metre and requirements for test reporting (test report content and traceability).
• Specialised tests: tensile tests at elevated and low temperatures and cyclic inelastic load testing (clauses detailing specimen preparation and equipment).

Typical use and users

Used by steel manufacturers, independent testing laboratories, construction product assessors, civil and structural engineers, contractors and procurement bodies for quality control, acceptance testing and verification of reinforcing steel products intended for reinforced and prestressed concrete structures. Design offices and regulatory authorities also reference these methods when specifying test evidence in contracts and standards.

Related standards

ISO 15630 is a multi-part series. Relevant related parts include ISO 15630-2:2019 (Test methods — Part 2: Welded fabric and lattice girders) and ISO 15630-3 (Test methods for prestressing steel; 2019 editions exist and later revisions have been published for part 3). Product standards and regional/adopted versions (for example EN ISO 15630-1) should be consulted for sampling rules and regional application.

FAQ

Q: What is this standard?

A: ISO 15630-1:2019 is Part 1 of the ISO 15630 series and specifies standardised chemical, mechanical and geometrical test methods for reinforcing bars, rods and wire used in concrete.

Q: What does it cover?

A: It covers tensile, bend/rebend and fatigue tests, chemical analysis, measurements of rib/indentation geometry and mass-per-metre determinations, plus specialised tests (e.g., at non-ambient temperatures) and requirements for test reports. It does not address sampling procedures, which are covered by product standards.

Q: Who typically uses it?

A: Steel manufacturers, testing laboratories, structural and material engineers, contractors and procurement/specification authors use it for product verification, quality control and contract compliance.

Q: Is it current or superseded?

A: ISO 15630-1:2019 is the current (3rd) edition published in February 2019 and was reviewed/confirmed in the ISO review cycle (confirmation noted in 2024). Users should check for any regional adoptions or subsequent amendments before relying on the standard for regulatory compliance.

Q: Is it part of a series?

A: Yes — ISO 15630 is a series of test-method parts. Part 1 covers bars, rods and wire; Part 2 covers welded fabric and lattice girders; Part 3 covers prestressing steel (and has been subject to later revision activity). Consult the other parts for test methods applicable to other reinforcement product forms.

Q: What are the key keywords?
