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 22034-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 17, Steel wire rod

and wire products.

ISO 22034 consists of the following parts, under the general title Steel wire and wire products:

⎯ Part 1: General test methods
⎯ Part 2: Tolerances on wire dimensions

3 Tensile test
3.1 General

The tensile test shall be carried out in accordance with ISO 6892 at ambient temperature.

3.2 Type of test piece

Test pieces shall be selected in accordance with ISO 377, using the full cross-section, i.e. they shall be

unmachined portions of wire.
3.3 Preparation of test pieces

The test pieces shall be straightened with care so as not to cause damage, with reference to ISO 377 and

ISO 6892.
3.4 Cross-sectional area

The actual test piece dimensions are used for tensile calculations, but the nominal dimensions may be used if

specified in the product standard or order. For non-circular wire, the original cross-sectional area may be

determined from the mass of a known length and its density.
3.5 Method of gripping the test pieces

When testing smaller diameters (less than or equal to 1 mm), it is recommended that the ends of the wire be

wrapped round a circular bar or disc and fastened to avoid breakages of the wire in the gripping zone.

3.6 Tensile testing of knotted wire

Carry out tensile testing of knotted wire in accordance with ISO 6892 with a simple knot in the middle of the

test piece.
4 Simple torsion test

The simple torsion test shall be carried out in accordance with ISO 7800. In the event of initial failure, a retest

shall be carried out (see ISO 404). Where possible the retest shall be conducted at a speed of

(1 ± 0,2) turns/s.
