BS EN 693:2001+A2:2011EN 693:2001+A2:2011 (E) 4 Introduction 0.1 This standard is applicable to hydraulic presses as defined in 3.10. 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 “Mach

23、inery“ Directive and associated EFTA Regulations. 0.3 The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery shall comply as appropriate with EN 292 for hazards which are not covered by this standard. 0.4 Complementary guidance is given in the A an

24、d 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 measures to be adopted by persons undertaking the design (as de

25、fined 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 mater

26、ials (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

27、 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 who

28、se 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 p

30、, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European standard only when incorporated

45、f this standard, the following terms and definitions apply. Further terms and definitions are provided in relevant A and B standards and in annex A of EN 292-2:1991/A1:1995. 3.1 ancillary device any device intended for use with the press tools and integrated with the press, e.g. devices for lubricat

46、ion, feed and ejection. 3.2 cycle automatic operating mode where the slide/ram repeats continuously or intermittently, all functions achieved without manual intervention into the danger zone after initiation.
