Steel wire ropes -- Test method -- Determination of measured breaking force

ISO 3108:2017 specifies a method of tensile test to destruction for determining the actual breaking force of steel wire ropes as given in ISO 2408. It is also applicable for other ropes, unless the International Standard concerned specifically excludes its use, or gives another method.

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.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

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 the following

URL: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 105, Steel wire ropes.

This second edition cancels and replaces the first edition (ISO 3108:1974), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— the following clauses have been added:
— Terms and definitions (see Clause 3);
— Principle (see Clause 4);
— Sample preparation (see Clause 5);
— Testing machine requirements (see Clause 6);
— Safety requirements (see 7.6);
— Testing result justification (see 7.8);

— the test speed of the load applied at approximately 10 Mpa per second after 80 % of F achieved

min

has been changed to the speed at the rate of not more than 0,5 % of F per second (see 7.6).

Steel wire ropes — Test method — Determination of
measured breaking force
1 Scope

This document specifies a method of tensile test to destruction for determining the actual breaking

force of steel wire ropes as given in ISO 2408.

It is also applicable for other ropes, unless the International Standard concerned specifically excludes

its use, or gives another method.
