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.
