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.

Stähle für die Bewehrung und das Vorspannen von Beton - Prüfverfahren - Teil 2: Geschweißte Matten und Gitterträger (ISO 15630-2:2019)

Dieser Teil von ISO 15630 legt die für geschweißte Matten und Gitterträgerin Betracht kommenden Prüfmethoden fest.
ANMERKUNG   In einigen Ländern wird der Begriff "Geschweißte Drahtbewehrung" an Stellen von "Geschweißte (Draht) Matte" verwendet.
Für nicht in diesem Teil der ISO 15630 festgelegte Prüfungen (z. B. Biegeprüfung, Rippen-/Profil-Geometrie, Masse je Meter) ist ISO 15630-1 anwendbar.

Aciers pour l'armature et la précontrainte du béton - Méthodes d'essai - Partie 2: Treillis soudés et treillis raidisseurs (ISO 15630-2:2019)

Le présent document spécifie des méthodes d'essai chimiques et mécaniques et des méthodes de mesure des caractéristiques géométriques applicables aux treillis soudés et aux treillis raidisseurs pour l'armature du béton.
NOTE       Dans certains pays, l'expression "armature constituée de fils soudés [welded wire reinforcement]» est utilisée à la place de «treillis soudé [welded (wire) fabric]».
Pour les essais non spécifiés dans ce document (par exemple, essai de pliage, géométrie des verrous/empreintes, masse linéique), l'ISO 15630‑1 s'applique.
Le présent document ne couvre pas les conditions d'échantillonnage qui sont spécifiées dans les normes de produit.

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

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.

Part 2:
Welded fabric and lattice girders
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.

SIST EN ISO 15630-2:2019
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
