Overview
EN ISO 15630-1:2019 - published by CEN and identical to ISO 15630-1:2019 - defines standardized test methods for reinforcing bars, rods and wire used in concrete. The document specifies chemical and mechanical test methods plus measurement procedures for geometrical characteristics of steel used for reinforcement. It does not cover sampling conditions (those are handled in product standards). Annex A lists options for agreement between contracting parties.
Key topics and technical requirements
This part of ISO 15630 focuses on test method definitions and includes requirements and procedures for:
- Tensile tests at room temperature - test pieces, equipment, procedure and interpretation of results.
- Bend and rebend tests - bending devices, rebending devices, artificial ageing and result evaluation.
- Axial force fatigue tests - principle, specimen preparation, force ranges, frequency and validity criteria.
- Chemical analysis - methods for determining chemical composition of reinforcing steel.
- Geometrical characteristic measurements - procedures to measure rib/indentation height, pitch, spacing, angle, flank inclination and widths.
- Relative rib/indentation area calculation (fR / fP) - measurement steps and formulae for determining rib or indentation area contributing to bond performance.
- Determination of deviation from nominal mass per metre - measurement accuracy and test procedures.
- Specialized tests - examples include tensile tests at elevated temperatures (principles and specimen provisions).
- General provisions - handling of test pieces and common definitions, symbols and normative references.
All methods are presented with test-piece requirements, equipment specs, step-by-step procedures and guidance on interpreting results.
Applications and who uses this standard
EN ISO 15630-1:2019 is essential for:
- Rebar manufacturers - to verify mechanical, chemical and dimensional conformity of products.
- Third‑party testing laboratories - to perform accredited rebar testing and report consistent results.
- Structural and geotechnical engineers - to interpret material test data for design and quality assurance.
- Construction contractors and specifiers - to set procurement criteria and acceptance testing requirements.
- Certification bodies and regulators - for compliance checks, inspection and type testing.
Practical uses include product verification, quality control, failure investigation, supplier qualification and contract compliance for reinforced and prestressed concrete projects.
Related standards
- Product standards address sampling conditions (not covered in this document) - users should apply relevant product and procurement standards when sampling specimens.
- See other parts of the ISO 15630 series for test methods related to different steel types and applications.

4 General provisions concerning test pieces
Unless otherwise agreed or specified in the product standard, the test piece shall be taken from the bar,
rod or wire in the as-delivered condition.
In the case of a test piece taken from a coil (rod or wire), the test piece shall be straightened prior to any
testing by a bend operation with a minimum amount of plastic deformation.
NOTE 1 The straightness of the test piece is critical for the tensile test at room temperature, the tensile test at
low temperature, the axial force fatigue test and the cyclic inelastic load test.
The means of straightening the test piece (manual, machine) shall be indicated in the test report.
For routine tests conducted by the manufacturers of reinforcing steels, the test information,
including the test piece condition and method of straightening, should be described within internal
documentation.
For the determination of the mechanical properties in the tensile test at room temperature, the tensile
test at low temperature, the axial force fatigue test and the cyclic inelastic load test, the test piece may
be artificially aged (after straightening if applicable), depending on the requirements of the product
standard.
If ageing is specified but the product standard does not specify the ageing treatment, the following
conditions should be applied: heating the test piece to 100 °C, maintaining at this temperature ±10 °C
for a period between 60 min and 75 min and then cooling in still air to ambient temperature.
NOTE 2 Depending on the conditions (number of test pieces, diameter of test pieces, type of heating device),
different heating times can be required for the test piece to reach the temperature of 100 °C. Unless otherwise
proven, a minimum heating time of 40 min can be assumed for the test pieces to reach the oven/bath operating
temperature.
If an ageing treatment is applied to the test piece, the conditions of the ageing treatment shall be stated
in the test report.
ISO 15630-1:2019(E)
5 Tensile test at room temperature
5.1 Test piece
In addition to the general provisions given in Clause 4, the free length of the test piece shall be sufficient
for the determination of the percentage elongation after fracture or the percentage total extension at
maximum force in accordance with 5.3.
If the percentage elongation after fracture (A) is determined manually, the test piece shall be marked in
accordance with ISO 6892-1.
If the percentage total extension at maximum force (A ) is determined by the manual method,
gt
equidistant marks shall be made on the free length of the test piece (see ISO 6892-1). The distance
between the marks shall be 20 mm, 10 mm or 5 mm, depending on the test piece diameter.
5.2 Test equipment
The testing machine shall be verified and calibrated in accordance with ISO 7500-1 and shall be at least
of class 1.
If an extensometer is used, it shall be of class 1 in accordance with ISO 9513 for the determination of
R ; for the determination of A , a class 2 extensometer (see ISO 9513) may be used.
p0,2 gt
Any extensometer used for the determination of the percentage total extension at maximum force (A )
gt
shall have a gauge length of at least 100 mm. The gauge length shall be indicated in the test report.
5.3 Test procedure
The tensile test shall be performed in accordance with ISO 6892-1. For the determination of R , if the
p0,2
straight portion of the force-extension diagram is limited or not clearly defined, one of the following
methods shall be applied:
— the procedure recommended in ISO 6892-1;
— the straight portion of the force-extension diagram shall be considered as the line joining the points
corresponding to 0,2F and 0,5F .
m m
F may be predefined as the force corresponding to the nominal tensile strength given in the
m
applicable product standard.
For stainless steels, other values than the ones mentioned above, applicable to carbon steels, may
be replaced by the appropriate values given in the product standard or agreed between the parties
involved.
In case of dispute, the second procedure shall be applied.
The test may be considered invalid if the slope of this line differs by more than 10 % from the theoretical
value of the modulus of elasticity.
For the calculation of tensile properties (R or R , R ), the nominal cross-sectional area shall be
eH p0,2 m
used, unless otherwise specified in the relevant product standard.
Where fracture occurs in the grips or at a distance from the grips less than 20 mm or d (whichever is
the greater), the test may be considered as invalid.
For the determination of percentage elongation after fracture (A), the original gauge length shall be five
times the nominal diameter (d), unless otherwise specified in the relevant product standard. In case of
dispute, A shall be determined manually.
The percentage total extension at maximum force (A ) shall be determined either by using an
gt
extensometer or by the manual method described in this document.
