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).

— grades S295W, S355WSE, S420W, S460W, S500W, S550W and pertaining requirements have been added;
— applicable thickness ranges have been added in the scope;
— terms and definitions concerning heat treatments have been deleted because defined in ISO 630-1;
— quality E (impact testing at −40 °C) has been added;
— list of options has been integrated in ISO 630-1;
— test units have been updated;
