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 World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL:

This document was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 1, Uniaxial testing.
This second edition cancels and replaces the first edition (ISO 6892-2:2011), of which it constitutes a minor
revision.
The main changes compared to the previous edition are as follows:
— a note has been added after the first sentence of 10.2.1;
— some references to subclauses of ISO 6892-1 have been deleted.

Introduction
In this document, two methods of testing speeds are described. The first, Method A, is based on strain rates
(including crosshead separation rate) with narrow tolerances (±20 %) and the second, Method B, is based
on conventional strain rate ranges and tolerances. Method A is intended to minimize the variation of the
test rates during the moment when strain rate-sensitive parameters are determined and to minimize the
measurement uncertainty of the test
