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).

— NOTE 1and NOTE 2 in Clause 1 have been removed;
— the normative references have been updated;
— the description for alternate loading assemblies has been added and the accuracy specification for apparatus has been updated;
— the preferred test specimen sizes have been removed and the requirement for the ratio of thickness/width of the specimen has been added;
— the document has been revised editorially.

A list of all parts in the ISO 6721 series can be found on the ISO website.
