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.

described in the ISO/IEC Directives, Part 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, Part 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

Introduction

This standard has been created in recognition of the particular hazards that are presented by Magnetic

clamping systems when integrated and installed in a plastics or rubber machine.

Hazards are frequently unique to a particular magnetic clamping system integrated in a plastics or

rubber machine. The number and types of hazards are directly related to the nature of the application,

the automation process and the complexity of the installation.

The risks associated with these hazards vary with the type of application and production process.

For the purpose of understanding requirements in this standard, a word syntax is used to distinguish

absolute requirements from recommended practices or suggested actions. The word “shall” is used

to identify requirements necessary for compliance with this standard. Such requirements have to be

accomplished unless an alternative instruction is provided, or a suitable alternative is determined by

a risk assessment. The word “should” is used to identify suggestions, recommended actions or possible

solutions for requirements, but alternatives are possible and the suggested actions are not absolute.

In recognition of the variable nature of hazards with the application of magnetic clamping system

integrated in a plastics or rubber machine, this standard provides guidance for the assurance of safety

in the design of magnetic clamping systems. Since safety in the use of magnetic clamping systems

is influenced by the integration in the machine and by the design and use of the different molds, a

supplementary, though equally important, purpose is to provide guidelines for the integration, the

installation and the use of magnetic clamping systems.

Providing for a safe magnetic clamping system depends on the cooperation of a variety of “stakeholders”

– those entities that share in a responsibility for the ultimate purpose of providing a safe working

environment.
Stakeholders may be identified as:
— MCS manufacturer;
— machine manufacturers (small, medium and large enterprises);

— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.);

— machine distributors, resellers, rebuilders and integrators;
— machine users/employers (small, medium and large enterprises);

— machine operators/employees (e.g. trade unions, organizations for people with special needs);

— service providers, e. g. for maintenance (small, medium and large enterprises).

The above-mentioned stakeholder groups have been given the possibility to participate in the drafting

process of this document.

All share the common goal of a safe machine. The requirements in this standard may be assigned to

one of the stakeholders, but overlapping responsibilities can involve multiple stakeholders in the same

requirements. While using this standard, the reader is cautioned that all of the requirements identified

may apply to them, even if not specifically addressed by “assigned” stakeholder tasks.

The MCS concerned and the extent to which hazards, hazardous situations or hazardous events are

indicated in the Scope of this document.
This document is a type-C standard as stated in ISO 12100:2010.

When requirements of this type-C standard are different from those which are stated in type-A or

type-B standards, the requirements of this type-C standard take precedence over the requirements of

the other standards for machines that have been designed and built according to the requirements of

this type-C standard.

Plastics and rubber machines — Clamping systems —
Part 1:
Safety requirements for magnetic clamping systems
1 Scope

This document specifies the essential safety requirements for the design, the construction and the

integration of magnetic clamping systems (MCS) for plastics and rubber machines (e.g. injection

molding machines, compression presses) and provides operational limits and information for their safe

use.

This standard deals with the basic hazards, hazardous situations or hazardous events that are listed in

Annex A, when an MCS is used utilizing magnetic force to affix a mold to the plate of a machine in which

it is integrated, and provides requirements to eliminate or adequately reduce the risks associated with

these hazards taking into consideration conditions of misuse that are reasonably foreseeable by the

manufacturer.

This standard also specifies requirements for the magnetic clamping system when integrated into a

machine. This standard does not deal specifically with hazards associated with production processes

or other processes (e.g. horizontal or vertical injection moulding processes). Other standards can be

applicable to these process hazards.

This document does not cover hydraulic, pneumatic or mechanical clamping systems.

This standard is not applicable to MCS, which are manufactured before the date of its publication.
