Anotácia textu normy ČSN EN 847-1 (496122):

This European Standard specifies all hazards arising from the use of tools for woodworking machines, and describes the methods for the elimination or reduction of these hazards by tool design and by the provision of information. This European Standard deals with milling tools (bore mounted, shank mounted) and circular saw blades, designed for chip removal machining (cutting) of wood and materials with similar physical characteristics to wood, hereinafter referred to as "tools". The hazards are listed in Clause 4. This European Standard does not cover any hazard related to the strength of shank of shank mounted milling tools. This European Standard does not apply to boring bits, eccentric single router cutters, cutters with cutting circle less than 16 mm and to tools used in rotary knife lathes and copying lathes where the hazard of ejection and contact with the tool is always prevented by a system of fixed guards and/or movable guards interlocked with guard-locking and/or self-closing guards. This European Standard is not applicable for tools according to this scope, which are manufactured before the date of its publication. NOTE: For woodworking machines and materials with similar physical characteristics to wood, see ISO 19085 1
