DIN EN 12750:2013-05

This standard contains specifications meeting the essential requirements set out in Annex I of EU Machinery Directive 2006/42/EC relating to machines which were placed on the European Economic Area (EEA) market for the first time, with the intent of simplifying the means of proving conformity with such requirements. 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. In connection with this standard, a "stationary machine" is a machine designed to be located on or fixed to the floor or other parts of the structure of the premises. 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: * in-feed devices (magazines, hoppers, etcetera); for mechanical in-feed devices which also prevent access to the in-feed opening; * the combination of single machines with any other machine as part of a line; * out-feed devices (for example, 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. This standard contains the German version of EN 12750:2012, which has been prepared by Technical Committee CEN/TC 142 "Woodworking machines - Safety" at the European Committee for Standardization (CEN). The following changes have been made in comparison with DIN EN 12750:2010-04: 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/min; b) In 5.2.1, Safety and reliability of control systems: Application of EN ISO 13849, that is by requiring PL for the machine's safety functions; c) In 5.2.7, Speed changing: concretion of requirements for different technologies; d) In 5.2.9, Integrated feed: Additional requirements related to the powered adjustment of spindle position, height adjustment of the feed mechanism, fences, table height, chip breakers and pressure shoes; e) In 5.3.4, Braking: concretion of requirements for different braking systems; f) In 5.3.5.2, Out-feed end of the machine: Additional requirements to prevent ejection from the machine; g) In 5.3.5.3, Use of glass bead cutting unit: Additional requirements for the glass bead cutting unit; h) In 5.3.7, Prevention of access to moving parts and ejection of parts of tools: concretion of requirements related to the safeguarding of the tools and ejection of parts of tools; i) In 5.4.2.1, Noise reduction at the design stage: Additional requirements related to integrated enclosures; j) In 5.4.2.2, Noise emission measurement: Additional noise emission test for machines having a maximum feed speed ≥ 40 m/min; k) In 5.4.3, Emission of chips and dust: Additional requirements related to the emission of chips and dust; l) In 6.3, Instruction handbook: The sermon to be provided by the manufacturer has been extended to a large extent. The national interests during the preparation are represented by Committee NA 060-06-01 AA "Sicherheit" ("Safety") of Technical Section "Woodworking machines" of the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of manufacturers and users of four sided moulding machines, and of the employers' liability insurance associations contributed to this standard.
