This document (EN 12750:2013) has been prepared by Technical Committee CEN/TC 142 “Woodworking machines Safety” (Secretariat: UNI, It
5、aly). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-06-01 AA Holzbearbeitungsmaschinen Sicher-heit of Section Holzbearbeitungsmaschinen. Representatives of manufacturers and users of
6、 four sided moulding machines, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are eith
7、er first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufact
8、urer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in this document have been published as DIN EN or DIN EN ISO Standards with the same number. There is no DIN Standard available which c
9、orresponds to the International Standard referred to. Amendments This standard differs from DIN EN 12750:2010-04 as follows: a) in Clause 1 “Scope”: the scope has been limited to machines having a maximum speed of the integrated work-piece feed of 200 m min1; b) in Subclause 5.2.1 “Safety and reliab
10、ility of control systems”: application of EN ISO 13849, i.e. by requiring PL for the machines safety functions; c) in Subclause 5.2.7 “Speed changing”: the requirements for different technologies have been rendered more precise; d) in Subclause 5.2.9 “Integrated feed”: additional requirements relate
11、d to the powered adjustment of spindle position, height adjustment of the feed mechanism, fences, table height, chip breakers and pressure shoes have been included; e) in Subclause 5.3.4 “Braking”: the requirements for different technologies have been rendered more precise; f) in Subclause 5.3.5.2 “
12、Out-feed end of the machine”: additional requirements to prevent ejection from the machine have been included; DIN EN 12750:2013-05 3 g) in Subclause 5.3.5.3 “Use of glass bead cutting unit”: additional requirements for the glass bead cutting unit have been included; h) in Subclause 5.3.7 “Preventio
13、n of access to moving parts and ejection of parts of tools”: the requirements related to the safeguarding of the tools and ejection of parts of tools have been rendered more precise; i) in Subclause 5.4.2.1 “Noise reduction at the design stage”: additional requirements related to integrated enclosur
14、es have been included; j) in Subclause 5.4.2.2 “Noise emission measurement”: an additional noise emission test for machines having a maximum feed speed 40 m min1 has been included; k) in Subclause 5.4.3 “Emission of chips and dust”: additional requirements related to the emission of chips and dust h
15、ave been included; l) in Subclause 6.3 “Instruction handbook”: the information to be provided by the manufacturer has been considerably extended.

42、ion This document has been prepared to be a harmonised standard to provide one means of conforming to the Essential Health and Safety Requirements of the Machinery Directive and associated EFTA Regulations. This document is a type C standard as defined in EN ISO 12100:2010. The machinery concerned a
43、nd the extent to which hazards, hazardous situations and events are covered is indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisio
44、ns of other standards, for machines that have been designed and built according to the provisions of this type C standard. The requirements of this document are directed to manufacturers and their authorised representatives of four sided moulding machines. This document is also useful for designers.
45、 This document also includes provisions and examples of information to be provided by the manufacturer to the user. Common requirements for tooling are given in EN 847-1:2005+A1:2007. DIN EN 12750:2013-05 EN 12750:2013 (E) 7 1 Scope This European Standard deals with all significant hazards, hazardou
46、s situations and events as listed in Clause 4, which are relevant to stationary four sided moulding machines with a maximum working width of 350 mm and a maximum speed of the integrated work-piece feed of 200 m/min, with electrical and/or electronic control system, hereafter referred to as “machines
47、“ designed to cut solid wood, chipboard, fibreboard, plywood and also these materials where these are covered with plastic laminate or edgings when they are used as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse of the machine (see 6.3 c). For
48、 the definition of a stationary machine, see 3.22. This European Standard deals also with hazards relating to the following optional work units: universal spindle; glass bead cutting unit. This European Standard is not applicable to machines designed for machining logs which have not previously been
49、 machined. This European Standard does not deal with any hazards relating to: a) in-feed devices (magazines, hoppers, etc.); NOTE For mechanical in-feed devices which also prevent access to the in-feed opening, see 5.3.7.2. b) the combination of single machines with any other machine as part of a line; c) out-feed devices (e.g. mechanical handling systems) except for hazards related to ejection from the machine due to climb cutting. This European Standard is not applicable to four sided moulding machines which are manufactured before the date
