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

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
