Machine tools - Safety - Hydraulic presses

1.1 This standard specifies technical safety requirements and measures to be adopted by persons undertaking the design (as defined in 3.11 of EN 292-1:1991), manufacture and supply of hydraulic presses which are intended to work cold metal or material partly of cold metal. 1.2 This 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 3.12 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. For the safeguarding of integrated manufacturing systems using presses, see also ISO 11161. 1.5 This standard does not cover machines whose principal designed purpose is: a) sheet metal cutting by guillotine; b) attaching a fastener, e.g. riveting, stapling or stitching; c) bending or folding; d) straightening; e) turret punch pressing; f) extruding; g) drop forging or drop stamping; h) compaction of metal powder; i) single purpose punching machines designed exclusively for profiles, e.g. for the construction industry. 1.6 This standard is applicable to machines built after its date of issue.
