british standard bs en693:2001machine tools safety hydraulic pressesthe european standard en 693:2001 has the status of abritish standardics 25.120.10no copying without bsi permission except as permitted by copyright lawbs en 693:2001national forewordthis british standard is the official english language version of en 693:2001. the uk is obliged to publish en 693:2001 as a british standard (bs en 693:2001). however, attention is drawn to the fact that during the development of this european standard the united kingdom has consistently voted against its approval as an en. the uk believes that the standard is deficient in certain safety requirements compared with the state of the art for these machines in the uk. the standard fails to satisfy some of the relevant essential requirements of the ec machinery safety directive (98/37/ec), as implemented in the uk by the supply of machinery (safety) regulations 1992(as amended), which it claims to meet.as part of bsis duty of care we draw attention to users of bs en 693:2001 of our concern that the standard contains inadequate requirements for protection of personnel against access to the danger zone at manually loaded/unloaded machines as specified in annex iv to the directive. the concerns relate specifically to clauses 5.3.2 and 5.3.3 in so far as the use of a two-hand control device(s) is concerned. when these devices are provided as the sole safeguard they do not adequately control the risks to other workers. bsi will assume no liability whatsoever for any failure on the part of any user of this standard to consider these aspects.the uk participation in its preparation was entrusted by technical committee mte/1, machine tools, to subcommittee mte/1/1, metal forming machine tools, which has the responsibility to:aid enquirers to understand the text;present to the responsible european committee any enquiries on the interpretation, or proposals for change, and keep the uk interests informed;monitor related international and european developments and promulgate them in the uk.a list of organizations represented on this subcommittee can be obtained on request to its secretary.cross-referencesthe british standards which implement international or european publications referred to in this document may be found in the bsi standards catalogue under the section

the latest by july 2001, and conflicting national standards shall be withdrawn at the latest by july 2001.this european standard has been prepared under a mandate given to cen by the european commission and the european free trade association, and supports essential requirements of eu directive(s).for relationship with eu directive(s), see informative annex za, which is an integral part of this standard. annexes a and b to this standard are normative, whereas annexes c to g and za are informative.this standard also contains a bibliography.according to the cen/cenelec internal regulations, the national standards organizations of the following countries are bound to implement this european standard: austria, belgium, czech republic, denmark, finland, france, germany, greece, iceland, ireland, italy, luxembourg, netherlands, norway, portugal, spain, sweden, switzerland and the united kingdom.0introduction0.1this standard is applicable to hydraulic presses as defined in 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 and associated efta regulations.0.3the 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.0.4complementary guidance is given in the a and 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. bsi 03-20011scope1.1this 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.1.2this 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.1.3the 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.1.4this 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 11161.1.5this 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.1.6this standard is applicable to machines built after its date of issue.2normative referencesthis european standard incorporates, by dated or undated

automaticoperating mode where the slide/ram repeats continuously or intermittently, all functions achieved without manual intervention into the danger zone after initiation3.3cycle operatingmovement of the slide/ram from the cycle start position (normally the top dead centre) to the bottom dead centre and back to the cycle stop position (normally the top dead centre)the operating cycle includes all operations carried out during this movement.3.4cycle singleoperating mode where each operating cycle of the slide/ram has to be positively actuated by the operator3.5dead centrespoints at which the tool, during its travel, is:-either nearest/closest to the die (generally it corresponds to the end of the closing stroke), known as the bottom dead centre (bdc); or-furthest from the die (generally it corresponds to the end of the opening stroke), known as the top dead centre (tdc).3.6 diefixed part of the tools used in a press3.7die cushionaccessory for a die which accumulates and releases, or absorbs, force as required in some press operations3.8early opening interlocking guardguard associated with an interlocking device which, if opened when any dangerous movement in the tools area has ceased, does not interrupt the operating cycle3.9guard locking devicemechanical device to maintain an interlocking guard gate in the closed and locked position until the risk of injury from the hazardous machine functions has passed3.10hydraulic pressmachine designed or intended to transmit energy by linear movement between closing tools by hydraulic means for the purpose of the working (e.g. forming or shaping) of cold metal or material partly of cold metal between the toolssuch energy is produced by the effects of hydrostatic pressure (see figures 1 and 2).3.11limited
