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.
