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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 15630-2 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 16, Steels for the

reinforcement and prestressing of concrete.

This second edition cancels and replaces the first edition (ISO 15630-2:2002), which has been technically

revised.

ISO 15630 consists of the following parts, under the general title Steel for the reinforcement and prestressing

of concrete — Test methods:
⎯ Part 1: Reinforcing bars, wire rod and wire
⎯ Part 2: Welded fabric
⎯ Part 3: Prestressing steel

Introduction

The aim of ISO 15630 is to provide all relevant test methods for reinforcing and prestressing steels in one

standard. In that context, the existing International Standards for testing these products have been revised

and updated. Some further test methods have been added.

Reference is made to International Standards on the testing of metals, in general, as they are applicable.

Complementary provisions have been given if needed.

Welded fabric
1 Scope

This part of ISO 15630 specifies test methods applicable to welded fabric 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 part of ISO 15630 (e.g. bend test, rib/indentation geometry, mass per

metre), ISO 15630-1 is applicable.
2 Normative references

references, only the edition cited applies. For undated references, the latest edition of the referenced

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 in the as-delivered condition.

In the case of a curved test piece, the test piece shall be straightened prior to any tests by a bend operation

with a minimum amount of plastic deformation.

NOTE The straightness of the test piece is critical for the tensile test and the fatigue test.

The means of straightening the test piece (manual, machine) shall be indicated in the test report .

For the determination of the mechanical properties in the tensile test and the fatigue test, the test piece may

be artificially aged, depending on the requirements of the relevant product standard.

1) For routine tests conducted by the reinforcing steel producers, the test information, including the test piece condition

and method of straightening, should be contained within internal documentation.

ISO 15630-2:2010(E)

If the product standard does not specify the ageing treatment, the following conditions should be applied:

+15

heating the test piece to 100 °C, maintaining at this temperature ±10 °C for a period of 1 h min and then

cooling in still air to the ambient 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.

Cross wires or bars, and the wire or bar not to be tested in a twin-wire or -bar sample, shall be cut off before

the test without damaging the wire or bar to be tested or the weld under test.
5 Tensile 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 percentage elongations 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 elongation at maximum force (A ) is determined by the manual method, 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 bar or wire 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 ;

p0,2
for the determination of A , a class 2 extensometer (see ISO 9513) may be used.

Any extensometer used for the determination of the percentage total elongation at maximum force (A ) 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 carried out 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
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
