Introduction
This document has been prepared to be a harmonised standard to provide one means of conforming to the
essential health and safety requirements of the Machinery Directive and associated EFTA Regulations.
This document is a type C standard as defined in EN ISO 12100-1:2003.
The machinery concerned and the extent to which hazards, hazardous situations and events covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The requirements of this document are directed to manufacturers and their authorised representatives of
numerically controlled (NC) boring machines and routing machines. It is also useful for designers.
This also includes examples of information to be provided by the manufacturer to the user.
Common requirements for tooling are given in EN 847-1:2005 and EN 847-2:2001.

plywood and also these materials where these are covered with plastic laminate or edgings when they are
used as intended and under the conditions foreseen by the manufacturer.
This document also applies to machines fitted with:
a) additional equipment for sawing, sanding and edge banding;
b) fixed or movable workpiece support;
c) mechanical, pneumatic, hydraulic or vacuum workpiece clamping;
d) automatic tool change facilities.
This document does not deal with the specific hazards of edge banding equipment fitted to NC boring
machines, NC routing machines and NC combined boring/routing machines.
This document is only applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are designed to use milling tools with a cutting circle diameter below 16 mm or
milling tools or saw-blades conforming to EN 847-1:2005 and EN 847-2:2001 and boring tools or sanding
wheels.
This document is not applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are designed to use grinding wheels.
This document is not applicable to single spindle hand fed/integrated fed routing machines.
NOTE Single spindle hand fed/integrated fed routing machines are dealt with in EN 848-2:2007.
This document does not deal with the specific hazards of ejection through curtains on machines with feeding
openings of which the distance between the workpiece support and the lower part of the partial enclosure in
the direction of the feed exceeds 400 mm.
This document is not applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are manufactured before the date of its publication as EN.
