Safety of woodworking machines - Chip and dust extraction systems with fixed installation - Safety related performances and safety requirements
This document sets out the safety related performance requirements and specifies the methods for elimination of hazards or the measures that shall be taken to minimise hazards, which cannot be eliminated, on chip and dust extraction systems with fixed installation as defined in 3.1.1 and 3.1.2, for the purpose of this standard, hereinafter referred to as extraction system, connected to woodworking machines, designed to process solid wood, chipboard, fibreboard, plywood and also these materials where these are covered with plastic laminate or edgings. The extraction and conveying system operates pneumatically by vacuum and/or pressure between ± 0,3 bar.
This standard does not apply to fixed installations with an air flow capacity below 6 000 m3h-1 installed indoors, or to moveable units with an air flow capacity below 6 000 m3h-1.
This standard does not apply to the extraction equipment, e.g. extraction hoods, ducts etc. within a woodworking machine i.e. up to and including the outlet to which the extraction system is coupled.
This standard does not:
a) apply to extraction systems connected to machines processing non-wood materials, such as plastic, plastic laminates, metals, glass or stone;
b) deal with the hazards from contact with or inhalation of dusts from wood coated with lacquer, plastic, aluminium and material with high additive contents or similar;
c) deal with shop fresh air supply;
d) apply to chip and dust extraction systems designed for Kst values above 200 bar ms-1.
The silo discharge system itself is excluded from this standard.
This document deals with the interaction with the silo discharge system if any.
This document covers the hazards relevant to these machines as stated in Clause 4. This document does not cover the hazards related to Electromagnetic Compatibility (EMC) as required by the EMC Directive 89/336/EEC dated 3-5-89.
Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmosph

d) gilt nicht für Absauganlagen in Verbindung mit Maschinen zur Bearbeitung von anderen Materialien als Holz, wie z. B. Kunststoffe, Kunststofflaminate, Metalle, Glas oder Stein;
e) behandelt nicht die Gefährdungen, die durch einen Kontakt oder das Einatmen von Staub von mit Lack behandeltem Holz, von Kunststoffen, Aluminium und Materialien mit hohem Anteil an Zusätzen oder ähnlichen Stoffen ausgehen;
f) behandelt nicht die Luftzuführung zu Arbeitsräumen;
g) gilt nicht für Absauganlagen für Holzstaub und Holzspäne, die für Werte von Kst über 200 bar ms-1 konstruiert sind;
h) gilt nicht für das Silo-Austragsystem;
i) behandelt nicht die Gefährdungen bezüglich der Elektromagnetischen Verträglichkeit (EMV), wie in der Richtlinie für Elektromagnetische Verträglichkeit 89/336/EWG (Datum: 1989-05-03) gefordert.
Machines pour le travail du bois - Installations fixes d'extraction de copeaux et de poussières - Performances relatives à la sécurité et prescriptions de sécurité
La présente Norme européenne spécifie les prescriptions de performance en matière de sécurité ainsi que les méthodes permettant d'éliminer les phénomènes dangereux ou les mesures destinées à limiter les risques qu'il est impossible de supprimer, pour les installations fixes d'extraction de copeaux et de poussières telles que définies en 3.1.1 et 3.1.2, pour les besoins de la présente norme, ci-après appelées installations d'extraction, raccordées aux machines à bois conçues pour l'usinage de bois massif, de panneaux de particules et de fibres, de contreplaqué, ainsi que ces matériaux lorsque leurs surfaces ou leurs chants sont recouverts de matière plastique stratifiée. L'installation d'extraction et de transport fonctionne pneumatiquement en dépression et/ou en pression dans une plage de ± 0,3 bar.
La présente norme ne s'applique pas aux installations fixes ayant une capacité de débit d'air inférieure à 6 000 m3/h-1 installées à l'intérieur des locaux, ou unités mobiles ayant une capacité de débit d'air inférieure à 6 000 m3/h-1.
La présente norme ne s'applique pas aux dispositifs d'extraction, par exemple dispositifs de captage, gaines, etc., situés dans la machine à bois, c'est-à-dire avant et au niveau de la sortie à laquelle est raccordée l'installation d'extraction.
La présente norme :
a) ne s'applique pas aux installations d'extraction raccordées à des machines d'usinage de matériaux autres que le bois, tels que matière plastique, matière plastique stratifiée, métaux, verre ou pierre ;
b) ne traite pas des phénomènes dangereux résultant du contact ou de l'inhalation de poussières de bois recouvert de laque, de matière plastique, d'aluminium et de matériau à forte teneur en additif ou similaire ;
c) ne traite pas de l'introduction d'air neuf dans l'atelier ;
d) ne s'applique pas aux installations d'extraction de copeaux et de poussières conçues pour des indices de Kst supérieurs à 200 bar ms-1.
La présente norme ne couvre pas le dispositif de décharge

Foreword
This document (EN 12779:2004) has been prepared by Technical Committee CEN/TC 142 “Woodworking
machines - Safety”, the secretariat of which is held by BSI.
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 June 2005 and conflicting national standards shall be withdrawn at the
latest by June 2005.
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(s), see informative Annex ZA, 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 12100-1:2003 for a description of A, B and C standards).
This standard for Chip and dust extraction systems with fixed installation will be followed by a separate
standard for Semi-stationary chip and dust extraction machines.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finl
