DIN EN 847-3:2013-12

This European Standard deals with hazards arising from the use of clamping devices for the fastening of milling tools and circular saw blades on woodworking machines and specifies the methods for the elimination or reduction of these hazards by the design of the clamping device and by the provision of information such as equations for calculating the test sample for clamping devices for shank-mounted tools. This document does not apply to arbours for spindle moulding machines in accordance with EN 848-1 or to clamping flanges for circular sawing blades to be used on circular sawing machines in accordance with the standard series EN 1870 and does not cover hazard related to the connection of the clamping device with the machine. Bore mounted tools which are mounted on an interchangeable arbour should be considered as a shank mounted tool. This document has been prepared by WG 8 "Woodworking tools - Safety" (secretariat: UNI, Italy) of CEN/TC 142 "Safety of woodworking tools". The responsible German working committee is NA 121-01-18 AA (previous designation FWS-B 4.4) "Sicherheit von Holzbearbeitungsmaschinen" ("Safety of woodworking tools") at FWS.
