This European Standard deals with all significant hazards, hazardous 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” 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 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 machined. This European Standard does not deal with any hazards relating to: a) in-feed devices (magazines, hoppers, etc.); 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 of its publication as EN.

| 6 | Foreword This document (EN 12750:2013) has been prepared by Technical Committee CEN/TC 142 “Woodworking machines – Safety”, the secretariat of which is held by UNI. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12750:2001+A1:2009. This document 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 2006/42/EC, see informative Annex ZA, which is an integral part of this document. The following most significant changes have been made in comparison with EN 12750:2001+A1:2009: Organisations contributing to the preparation of this European Standard include the European Manufacturers Association “EUMABOIS”. |
| 7 | The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement the relevant A and B Standards on the subject of general safety (see Introduction of EN ISO 12100:2010 for a description of A, B and C standards). |
