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 partin the work.ISO collaborates closely

with the International Electrotechnical Commission(IEC)onall 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 document 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 ).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a)

patent(s).ISO takes no position concerning the evidence,validity or applicability of any claimed patent

rights in respect thereof.As of the date of publication of this document,ISO had not received notice of (a)

patent(s)which may be required to implement this document.However,implementers are cautioned that

this may not represent the latest information,which may be obtained from the patent database available at

www.iso.org/patents .ISO shall not be held responsible for identifying any or all such patent rights.

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of 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 www.iso.org/iso/foreword.html .

This document was prepared by Technical Committee ISO/TC164,Mechanicaltesting ofmetals,Subcommittee

SC 3, Hardness testing, in collaboration with the European Committee for Standardization(CEN)Technical

Committee CEN/TC 459/SC 1,Test methods for steel [other than chemical analysis,in accordance with thee

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition(ISO 14577-3:2015),which has been technically

revised.

The main changes are as follows:

一Specification of the shape of the reference block.

一Modifications in the procedure for the verification ofthe indenter.

一Testing cycle requirements.

一Changing the conditions for the verification of the uniformity of the reference blocks.

一Annex A was added.

A list ofall parts in the ISO 14577 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user's national standards body.A

complete listing of these bodies can be found at www.iso.org/members.html .
