BS EN 16770:2018 pdf free.Safety of woodworking machines – Chipand dust extraction systems for indoorinstallation – Safety requirements.
BS EN 16770 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 towoodworking machines,when they are used as intended and under the conditions foreseen by themanufacturer, 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 Key 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 publicationas a European Standard.
