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 8, Ships and marine technology, Subcommittee SC 8, Ship design.

This second edition cancels and replaces the first edition (ISO 3797:1976), which has been technically revised.

The main changes are as follows:

• the types and the scope of application have been extended;
• the dimensions of ladders have been extended;
• a fall protection requirement has been added;
• the steel grade of material has been specified;
• the requirements of surface treatment, appearance and tolerance have been specified.

1 Scope
