19、ument (EN 12779:2015) has been prepared by Technical Committee CEN/TC 142 “Woodworking machines - Safety”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by
20、May 2016, and conflicting national standards shall be withdrawn at the latest by May 2016. 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 rig
21、hts. This document supersedes EN 12779:2004+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 the basic requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex Z
22、A which is an integral part of this document. The European Standards produced by CEN/TC 142 are particular to woodworking machines and compliment 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). NOT
23、E Extraction systems as a whole are not intended to be installed in areas, where the presence of potentially explosive atmosphere needs to be taken into account. In relation to the previous version of the standard, the following main modifications have been made: The scope has been adjusted to meet
24、the fields of application of the standard; The requirements for safety related controls have been modified for clarification; The requirements for electrical equipment and installations have been modified for clarification; The requirements for fire and explosion protection have been modified for cl
25、arification; The requirements for noise protection have been modified for clarification; The requirements for protection against hazardous substances have been modified for clarification; The requirements for silos have been modified for clarification; A new annex for examples of extraction systems
26、have been added for clarification; A new annex for the classification of places where explosive atmosphere may occur have been added for clarification. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europ

BS EN 12779:2015EN 12779:2015 (E) 6 Introduction This standard has been prepared to be a harmonized standard to provide one means of conforming to the Essential Health and Safety Requirements of the
29、Machinery Directive and associated EFTA Regulations. This document is a type “C” standard as defined in EN ISO 12100:2010. This document is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small,
30、 medium and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance etc.). Others can be affected by the level of machinery safety achieved with the means of the document by the above-mentioned stakeholder groups: machine users/employers (smal
31、l, medium and large enterprises); machine users/employees (e. g. trade unions, organizations for people with special needs); service providers, e.g. for maintenance (small, medium and large enterprises); consumers (in case of machinery intended for use by consumers). The above-mentioned stakeholder
32、groups have been given the possibility to participate at the drafting process of this document. The machinery concerned and the extent to which hazards, hazardous situations and events covered are indicated in the scope of this document. When provisions of this type C standard are different from tho
33、se, which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of other standards, for machines that have been designed and built in accordance with the provisions of this type C standard. The requirements of this document are directed to ma
34、nufacturers and their authorized representatives of chip and dust extraction systems. This document also includes information to be provided by the manufacturer to the user. BS EN 12779:2015EN 12779:2015 (E) 7 1 Scope This European Standard deals with the significant hazards, hazardous situations an
35、d events relevant for chip and dust extraction systems for fixed installation and for connection with machines for working on solid wood (including hard wood), wood-based materials and wood-like materials, when they are used as intended and under the conditions foreseen by the manufacturer, includin
36、g reasonably foreseeable misuse. This European Standard deals also with the technical requirements to minimize the hazards in connection with the temporary storage of wood dust, chips and shavings in a silo, bin or container including charging and discharge systems. This European standard does not a
37、pply to: a) chip and dust extraction systems with filters installed indoors (covered by prEN 16770); b) extraction equipment (e.g. extraction hoods, ducts) within a woodworking machine including the outlet to which the extraction system is connected; c) chip and dust extraction systems designed for
38、KSTvalues above 200 bar ms1; d) mechanical conveying systems between filter and storage facility; e) extraction systems and conveying systems with underpressure below 0,3 bar or overpressure above 0,3 bar; f) storage devices for pressed wood products (e.g. pellets) and humid shavings. Requirements f
39、or containers are not dealt with in this standard. This European Standard is not applicable to machines which are manufactured before the date of its publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensa
