1.1 This European 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 pneumatic presses the intended use of which is the cold working of metal or material partly of metal as defined in 3.1.13 and hereafter referred as machines.
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.
1.2 This standard also covers pneumatic presses:
- whose primary intended use is the cold working of metal, which are to be used in the same way to work other sheet materials (e.g. cardboard, plastic, rubber, leather) and metal powder;
- with an intermediate pneumatic/hydraulic intensifier.
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 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. 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 standard does not cover machines whose principal designed purpose is:
a) sheet metal cutting by guillotine;
b) bending or folding by pneumatic press brakes or folding machines;
c) spot welding;
d) tube bending;
e) straightening;
f) drop stamping;
g) working by pneumatic hammer;
h) compaction of metal powder.
Special pneumatic machines for assemblying or calibrating are not covered but this standard may be used as a basis for there machines.
1.6 This standard does not cover the safety requirements related to the use of PES or PPS. They will be dealt with a
