4、 authoritative.02.14DIN EN 12622:2014-02 2 A comma is used as the decimal marker. National foreword This standard includes safety requirements. This document (EN 12622:2009+A1:2013) has been prepared by Technical Committee CEN/TC 143 “Machine tools Safety” (Secretariat: SNV, Switzerland). The respon
5、sible German body involved in its preparation was the Normenausschuss Werkzeugmaschinen (Machine Tools Standards Committee), Working Committee NA 122-00-10-01 UA Pressen und Umformmaschinen Sicherheit. This standard contains specifications meeting the essential requirements set out in Annex I of the
6、 “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to hydraulic press brakes that are either first placed on the market or commissioned within the EEA. This st
7、andard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requiremen
8、ts of the Machinery Directive (“presumption of conformity”). Amendments This standard differs from DIN EN 12622:2010-04 as follows: a) the amendment according to Draft Standard E DIN EN 12622:2013-05 has been incorporated. Clause 5 “Safety requirements and/or measures” has been completely restructur
9、ed; a description of safety functions and safety related parts of control systems with categories assigned and/or performance levels required in accordance with EN 13849-1:2006 (see Tables 2 and 3) has been included; Subclauses 5.2.7 “Use of electronic components” and 5.3.3 “Production modes” have b
10、een added; new safety functions and new safety devices have been added: a stop work-piece support movement (see 5.2.5.6), monitoring of slow speed (see 5.2.5.7), laser actuated AOPD (see 5.1.1.5), AOPDDR scanner systems (see 5.1.1.7.1) and ESPE using AOPD when used in automatic cycle as a trip devic
11、e (see 5.1.1.8); b) the German version of Subclause 5.5.4.3 has been revised and Subclause 5.5.10.3 has been added; c) Figure E.1 has been revised. d) the standard has been editorially revised.

DIN EN 12622:2014-02 EN 12622:2009+A1:2013 (E) 5 Introduction This European Standard is a C type standard as defined in EN ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations and events are covered
40、 are indicated in the scope of this standard. When provisions of this C type standard are different from those which are stated in A or B standards, the provision of this C type standard take precedence over the provisions of the other standards for machines that have been designed and built accordi
41、ng to the provisions of this C type standard. In addition, press brakes comply as appropriate with EN ISO 12100-1 and EN ISO 12100-2 for hazards which are not covered by this standard. The requirements of this European Standard concern designers, manufacturers, suppliers and importers of machines de
42、scribed in the scope. This European Standard also includes information to be provided by the manufacturer to the user. DIN EN 12622:2014-02 EN 12622:2009+A1:2013 (E) 6 1 Scope This European Standard specifies technical safety requirements and protective measures to be adopted by persons undertaking
43、the design, manufacture and supply of hydraulic press brakes which are designed to work cold metal or material partly of metal and hereafter referred to as machines. This European Standard also covers hydraulic press brakes, whose primary intended use is the cold working of metal, which are to be us
44、ed in the same way to work other sheet materials such as cardboard or plastic. The requirements in this European Standard take account of intended use, including foreseeable misuse as defined in 3.22 of EN ISO 12100-1:2003. This European Standard presumes access to the press brake from all direction
45、s, deals with the hazards described in Clause 4, and specifies the safety measures for both the operator and other exposed persons. This European Standard also applies to: ancillary devices which are an integral part of the press brake, e.g. back gauges and adjustable front sheet supports; machines
46、which are integrated into an automatic production line where the hazards and risk arising are comparable to those of machine working separately. The requirements of this European Standard apply to all hydraulic press brakes whatever the technology used in their control system, e.g. electromechanical
47、 and/ or electronic. This European Standard does not apply to machines whose principal designed purpose is: a) sheet folding by rotary action; b) tube and pipe bending by rotary action; c) roll bending. This European Standard applies to machines built after the date of issue of this European Standar
48、d. This European Standard does not cover the safety aspect of automatic loading and unloading equipment. Some guidance how to take into account additional automatic loading and unloading equipment can be found in ISO 11161. 2 Normative references The following referenced documents are indispensable
