Safety of woodworking machines - Chip and dust extraction systems for indoor installation - Safety requirements

This document deals with all significant hazards, hazardous situations and events as listed in Clause 4, relevant for chip and dust extraction systems for indoor use designated to be connected to woodworking machines, when they are used as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse.
This document does not apply to:
a)   extraction systems with a nominal volume flow rate above 8 000 m3 h−1 and/or a volume of the dust loaded part of the dust extractor above 3,5 m3;
b)   vacuum cleaners according to EN 60335-2-69;
c)   extraction systems with fans installed in the dust loaded part;
d)   extraction equipment (e.g. extraction hoods, ducts) within a woodworking machine, i.e. up to and including the outlet to which the extraction system is connected;
e)   extraction systems designed for dust with KST values above 200 bar ms−1, minimum ignition energy below 10 mJ and/or lower explosion level below 30 g m−3;
f)   extraction systems designed for aspiration of explosive atmospheres, e.g. dust load > 50 % lower explosion level;
g)   systems designed for extraction of machines with a higher risk of causing ignition sources.
This document is not applicable to machines which are manufactured before the date of its publication as a European Standard.

Sécurité des machines pour le travail du bois - Systèmes d'extraction de copeaux et de poussières pour installation en intérieur - Prescriptions de sécurité

Le présent document traite de tous les phénomènes dangereux, situations et événements dangereux significatifs, tels qu'énumérés dans l'Article 4, applicables aux systèmes d'extraction de copeaux et poussières utilisés en intérieur, conçus pour être raccordés aux machines à bois, lorsqu’ils sont utilisés comme prévu et dans les conditions prévues par le fabricant, incluant une mauvaise utilisation raisonnablement prévisible.
Le présent document ne s’applique pas aux :
a)   systèmes d'extraction ayant un débit volumique nominal supérieur à 8 000 m³ h-1 et/ou un volume de la partie chargée en poussières de l'extracteur de poussières supérieur à 3,5 m³ ;
b)   aspirateurs conformes à l'EN 60335-2-69 ;
c)   systèmes d'extraction dont les ventilateurs sont installés dans la partie chargée en poussières ;
d)   équipements d'extraction (par exemple, buses de captage, conduits) situés dans une machine à bois, c'est-à-dire jusqu’à et y compris la sortie à laquelle le système d'extraction est raccordé ;
e)   systèmes d'extraction conçus pour les poussières d’indice KST supérieur à 200 bar m s-1, une énergie minimale d'inflammation inférieure à 10 mJ et/ou un niveau inférieur d'explosivité inférieur à 30 g m−³ ;
f)   systèmes d'extraction conçus pour l'aspiration des atmosphères explosives, par exemple, une charge de poussière > 50 % au niveau inférieur d'explosivité ;
g)   systèmes conçus pour l'extraction des machines présentant un risque plus important de génération de sources d'inflammation.
Le présent document n’est pas applicable aux machines qui ont été fabriquées avant sa date de publication comme Norme européenne.

Varnost lesnoobdelovalnih strojev - Odsesovalni sistemi za lesne odrezke in prah za notranjo inštalacijo - Varnostne zahteve

Ta dokument obravnava vse pomembne nevarnosti, nevarne okoliščine ter dogodke iz točke 4 v zvezi z odsesovalnimi sistemi za lesne odrezke in prah za notranjo uporabo, ki so predvideni za priključitev na stroje, zasnovane za rezanje masivnega lesa (vključno s trdim lesom), lesnih materialov ter lesu podobnih materialov, kadar se uporabljajo v skladu s predvidenim namenom in v pogojih, ki jih predvidi proizvajalec, vključno z razumno pričakovano nepravilno uporabo.
Ta evropski standard se ne uporablja za:
a) odsesovalne sisteme z nazivnim pretokom nad 8000 m³/h in/ali prostornino s prahom obremenjenega predela izločevalnika prahu nad 3,5 m³;
b) sesalnike v skladu s standardom EN 60335-2-69/A2:2013;
c) odsesovalne sisteme z ventilatorji, nameščenimi v predelu, obremenjenem s prahom;
d) odsesovalno opremo (npr. odsesovalni pokrovi, vodi) v notranjosti lesnoobdelovalnega stroja, tj. do in vključno z odvodom, na katerega je priključen odsesovalni sistem;
e) odsesovalne sisteme, zasnovane za prah z vrednostmi KST nad 200 bar ms-1, najmanjšo vžigno energijo pod 10 mJ in/ali nižjo stopnjo eksplozivnosti pod 30 g/m³;
f) odsesovalne sisteme, zasnovane za aspiracijo eksplozivnih atmosfer, npr. obremenitev prahu > 50 % nižje stopnje eksplozivnosti;
g) sisteme, zasnovane za izločanje iz strojev z večjim tveganjem povzročitve virov vžiga;
h) silose.
Ta evropski standard se ne uporablja za stroje, ki so bili proizvedeni pred objavo tega dokumenta kot standarda EN.
