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, 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, 2 (see www.iso.org/directives ).

This document was prepared by Technical Committee ISO/TC 199, Safety of machinery.

Introduction

This document was developed to provide information about systems incorporating measures that can be introduced into machinery, especially in IMS for reducing risks based on human factors.

Due to lack of human attentiveness during any task performed in a hazard zone (for example, inspections, maintenance or set-up), safeguarding supportive systems can be used as a technical measure to minimize the probability of dangerous human errors occurring.

1 Scope

This document provides guidance for the design and integration of a safeguarding supportive system (SSS) which is intended to include a mode selection as part of an SRP/CS or to add a layer of personnel authentication and authorization to an IMS designed according to ISO 11161.

This document is meant to be used in conjunction with ISO 11161.

This document is applicable to the SSS but does not address personnel qualification and competency.
