0 Introduction
0.1
This standard is applicable to hydraulic press brakes as defined in 3.1.9.
0.2
This standard has been prepared to be a harmonized standard to provide one means of conforming
with the essential safety requirements of the Machinery Directive 98/37/EEC and associated EFTA
Regulations. It is a type C standard as described in EN 292–1:1991.
0.3 The extent to which hazards are covered is indicated in the scope of this standard.
0.4 Complementary guidance is given in the type A and type 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.
1 Scope
1.1 This standard specifies technical safety requirements and protective measures to be adopted by
persons undertaking the design (as defined in 3.11 of EN 292-1:1991), manufacture and supply of hydraulic
press brakes which are intended for cold working of metal or material partly of metal.
1.2
This standard also covers hydraulic press brakes, whose primary intended use is the cold working of
metal, which are to be used in the same way to work other sheet materials such as cardboard or plastic.
1.3 The requirements in this standard take account of intended use, as defined in 3.12 of EN 292-1:1991.
This standard presumes access to the press brake from all directions, deals with the hazards described in
clause 4, and specifies the safety measures for both the operator and other exposed persons.
1.4
This standard also applies to ancillary devices which are an integral part of the press brake, e.g. back
gauges and adjustable front sheet supports. For the safeguarding of integrated manufacturing systems using
press brakes, see also prEN 1921: 1995.
1.5 This standard does not cover machines whose principal designed purpose is:
a) sheet folding by rotary action;
b) tube and pipe bending by rotary action;
c) roll bending.
1.6 This standard applies to machines built after its date of issue.
NOTE An amendment is under preparation to take into account the use of laser/scanner devices for the
safeguarding of operators on press-brakes.
