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 ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Introduction

The objective of a manual load/unload station is to allow an operator to interface directly with an industrial robot system, e.g. feed/remove material into and out of a robot cell. The layout of the robot cell is designed to provide a work area that is free of hazards and to lessen the motivation to circumvent or defeat the designed safeguarding.

This document supplements the requirements for industrial robot system safety specified in ISO 10218-2:2011, 5.10.6. It provides additional guidance for manual load/unload stations that are lower than 1 400 mm, to permit the work to be performed in an ergonomic manner while maintaining safety and providing guidance for an alternative method of impeding access to the robot cell. ISO 14738, ISO 6385 and ISO 10218-2:2011, Annex A, provide further information on potential ergonomic hazards

Implementing ISO 10218-2 involves carrying out a comprehensive risk assessment, which is used to identify all hazards associated with the manual load/unload process. This document provides guidance on mitigation of the risks to the operator. The risk assessment needs to take account of foreseeable misuse, with mitigation provided.

1 Scope

This document is applicable to robot systems for manual load/unload applications in which a hazard zone is safeguarded by preventing access to it. For this type of application, it is important to consider the need for both access restrictions to hazard zones and for ergonomically suitable work places.

This document supplements ISO 10218-2:2011 and provides additional information and guidance on reducing the risk of intrusion into the hazard zones in the design and safeguarding of manual load/unload installations.
