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 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).

This document was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee SC 3, Hardness testing, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 459, ECISS - European Committee for Iron and Steel Standardization, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This third edition of ISO 4545‑1, together with ISO 6507‑1:2023, cancels and replaces ISO 4516:2002, ISO 4545‑1:2017and ISO 6507‑1:2018, which have been technically revised.

The main changes are as follows:

— Scope revised to include testing on metallic coatings and other inorganic coatings;
— added subclause 7.5 on metallic and other inorganic coatings;
— added Annex F to cover coatings specific requirements;
— updated references.

A list of all parts in the ISO 4545 series can be found on the ISO website.
