Steel for the reinforcement and prestressing of concrete - Test methods - Part 2: Welded fabric and lattice girders (ISO 15630-2:2019)
This document specifies chemical and mechanical test methods and measurement methods of geometrical characteristics applicable to welded fabric and lattice girders for the reinforcement of concrete.
NOTE In some countries, the expression "welded wire reinforcement" is used in place of "welded (wire) fabric".
For those tests not specified in this document (e.g. bend test, rib/indentation geometry, mass per metre), ISO 15630-1 is applicable.
This document does not cover the sampling conditions that are dealt with in the product standards.
A list of options for agreement between the parties involved is provided in Annex A.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by ISO/TC 17, Steel, Subcommittee SC 16, Steels for the reinforcement and
prestressing of concrete.
This third edition cancels and replaces the second edition (ISO 15630-2:2010), which has been
technically revised. Changes have been introduced in the title (the addition of lattice girders), the
Introduction and Clauses 1, 2 and 4, 5.3, Clause 8 (only the title), 8.3, 8.4.5 and 8.4.6. In Clauses 7 and
10, the titles have been slightly simplified and the clauses have been subdivided to cover both welded
fabric and lattice girders. A new Clause 11 has been added for “specialized” tests. The Bibliography has
been updated and the dated references have been replaced by undated references.
A list of all parts in the ISO 15360 series can be found on the ISO website.

Introduction
The aim of ISO 15630 (all parts) is to provide all relevant test methods for reinforcing and prestressing
steels in one standard series.
This document covers standard test methods (see Clauses 5 to 10), as well as specialized test methods
(gathered in Clause 11) that are not commonly used in routine testing and that should only be considered
where relevant (or specified) in the applicable product standard.
Reference is made to International Standards on the testing of metals, in general, as they are applicable.
Complementary provisions have been given if needed.

1 Scope
This document specifies chemical and mechanical test methods and measurement methods of
geometrical characteristics applicable to welded fabric and lattice girders for the reinforcement of
concrete.
NOTE In some countries, the expression “welded wire reinforcement” is used in place of “welded (wire)
fabric”.
For those tests not specified in this document (e.g. bend test, rib/indentation geometry, mass per
metre), ISO 15630-1 is applicable.
This document does not cover the sampling conditions that are dealt with in the product standards.
A list of options for agreement between the parties involved is provided in Annex A.

4 General provisions concerning test pieces
Unless otherwise agreed or specified in the product standard, the test pieces shall be taken from the
welded fabric or lattice girders in the as-delivered condition.
In the case of a curved test piece, 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, depending on the requirements of the relevant product standard.

ISO 15630-2:2019(E)
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 the 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.
The test piece shall include at least one welded intersection in the free length.
Cross wires or bars, and the wire or bar not to be tested in a twin-wire or twin-bar sample, shall be cut
off before the test without damaging the wire or bar to be tested or the weld under test.

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 w
