This document (EN 848-2:2007+A2:2012) has been prepared by Technical Committee CEN/TC 142 “Wood-working machines Safety” (Secretariat: UNI, Italy). The respons

6、ible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-06-01 AA Holzbearbeitungs-maschinen Sicherheit of Section Holzbearbeitungsmaschinen. Representatives of manufacturers and users of single spindle h

7、and fed/integrated fed routing 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 tha

8、t are either 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,

9、a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with th

10、e same number. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available, except for: HD 22.4 S4:2004 DIN EN 50525-2-21 Amendments This standard differs from DIN EN 848-2:2010-04 as follows: a) Clause 1 “Scope” has be

11、en extended to include machines used for working hardened plastic materials with similar physical characteristics as wood; b) Clause 2 “Normative references” has been updated; c) in Subclause 5.2 “Controls” the design requirements for control circuits in certain categories have been replaced by spec

12、ifications for performance levels; d) the former Subclause 5.2.1.2 “Use of well-tried components” has been deleted; e) the former Subclause 5.2.8 “Spindle speed monitoring” has been completely revised and the title has been replaced with “Spindle speed control”; f) Subclause 5.3.4 “Braking” has been

13、 completely revised; g) Subclause 5.3.5 “Devices to minimise the possibility or the effect of ejection” now includes the description and an example of an enveloping guard; DIN EN 848-2:2013-01 3 h) Annex C (normative) “Impact test method for guards” has been added including tests on guards materials

14、, unless they are in accordance with Subclause 5.3.8 “Characteristics of guards and safety devices”; i) Subclause 5.4.3 “Emission of chips and dust” has been revised to include further requirements; j) the former Annex A (informative) “Use of well tried components” has been deleted; k) Annex ZA (inf

40、 EN 848-2:2007+A2:2012 (E) 5 Introduction This document has been prepared to be a harmonised standard to provide one means of conforming to the essential safety requirements of the Machinery Directive and associated EFTA Regulations. This document is a type C standard as stated in #EN ISO 12100:2010

41、$. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are 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

42、 precedence over the provisions 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 single spindle hand fed/integrated fed routi

43、ng machines. It is also useful for designers. This document also includes examples of information which are to be provided by the manufacturer to the user. Common requirements for tooling are given in #EN 847-1:2005+A1:2007$, EN 847-2:2001 and EN 847-3:2004. DIN EN 848-2:2013-01 EN 848-2:2007+A2:201

44、2 (E) 6 1 Scope This document !specifies all significant“ hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable single spindle hand fed/integrated fed routing machines with fixed head but allowing only movement along the axis of the tool dur

45、ing machining hereinafter referred to as “machines“ designed to cut solid wood, chip board, fibreboard, plywood and also these materials if they are covered with plastic laminate, edgings or veneer when they are used as intended and under the conditions foreseen by the manufacturer #including reason

46、ably foreseeable misuse$. #For the definition of stationary and displaceable machine see 3.2.17 and 3.2.18. Machines which are designed to work wood based materials may also be used for working hardened plastic materials with similar physical characteristics as wood.$ This document does not apply to

47、: a) inverted pin routers and radial arm routers (machines where the work piece is fixed and the tool head is manually moved); b) NC boring machines and NC routing machines; #NC boring machines and NC routing machines are dealt with in EN 848-3:2007+A1:2009.$ c) hand-held routers or any adaptation p

48、ermitting their use in a different mode, e.g. bench mounting; #NOTE 1$ Hand-held motor-operated electric tools are dealt with in #EN 60745-1:2009$ together with EN 60745-2-17:2003. d) routing machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand.
