Introduction

This standard has been prepared to be a harmonised standard to provide one means of conforming with the

essential safety requirements of the Machinery Directive and associated EFTA Regulations.

This document is a C-type standard as stated in EN ISO 12100-1.

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are

indicated in the scope of this standard.

When provisions of this C type standard are different from those which are stated in A or B standards, the provision

of this C type standard take precedence over the provisions of the other standards for machines that have been

designed and built according to the provisions of this C type standard.

Complementary guidance is given in the A and B standards to which reference is made in the text (see clause 2).

The figures are intended to be examples only and not to give the only interpretation of the text.

The requirements of this European Standard concern designers, manufacturers, suppliers and importers of

machines described in the scope.

This standard also includes information to be provided by the manufacturer to the user.

1 Scope

1.1 This European Standard specifies technical safety requirements and measures to be adopted by persons

undertaking the design, manufacture and supply of mechanical presses with part revolution clutch hereinafter

called presses which are intended to work cold metal or material partly of cold metal.

NOTE The design of a machine includes the study of the machine itself, taking into account all phases of its “life”,

i.e. construction, transport and commission (including assembly, installation and adjustment), use (including setting,

teaching/programming or process changeover, operation, cleaning, fault finding and maintenance) and de-

commissioning, dismantling and, as far as safety is concerned, disposal, and the drafting of the instructions related

to all above-mentioned phases of the “life” of the machine (except construction), dealt with it in 6.5 of EN ISO

12100-2:2003.

1.2 This European Standard also covers presses, whose primary intended use is to work cold metal, which are

to be used in the same way to work other sheet materials (such as cardboard, plastic, rubber or leather), and metal

powder.

1.3 The requirements in this standard take account of intended use, as defined in 3.22 of EN ISO 12100-1:2003.

This standard presumes access to the press from all directions, deals with the hazards during the various phases

of the life of the machine described in clause 4, and specifies the safety measures for both the operator and other

exposed persons.

1.4 This European Standard also applies to ancillary devices which are an integral part of the press. This

standard also applies to machines which are integrated into an automatic production line where the hazards and

risk arising are comparable to those of machines working separately.

1.5 This European Standard does not cover mechanical presses with full revolution clutch.

1.6 This European Standard does not cover machines whose principal designed purpose is:

a) sheet metal cutting by guillotine;
---------------------- Page: 7 ----------------------

4 List of significant hazards

4.1 The list of hazards contained in Table 1 is the result of a risk assessment, carried out as required by

EN 1050, for all mechanical presses covered by the scope of this standard. The technical measures and

information for use contained in Clauses 5 and 7 and Annexes A, B, C, E and F are based on the risk assessment,

and deal with the identified hazards by either eliminating them or reducing the effects of the risks they generate.

4.2 Risk assessment assumes foreseeable access from all directions, as well as overruns, unexpected and

unintended strokes or gravity falls. Risks to both the operators and other persons who can have access to the

danger zones are identified, taking into account all hazards which can occur during the life of the press. The

assessment includes an analysis of the effect of failure in the control system.

4.3 In addition, the user of this standard, i.e. the designer, manufacturer or supplier, shall conduct a risk

assessment in accordance with EN 1050 with particular attention to:

 the intended use of the press including maintenance, tool-setting and cleaning, and its reasonably foreseeable

misuse;

 the identification of the significant hazards associated with the press (see 4.4).

4.4 Table 1 of this standard is a list of significant hazards and their related danger zones normally associated

with a mechanical power press. As part of the risk assessment, the designer shall verify whether the list of hazards

in Table 1 is exhaustive and applicable to the press under consideration.
