Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

The committee responsible for this document is ISO/TC 39, Machine tools, Subcommittee SC 4,
Woodworking machines.
This document is intended to be used in conjunction with ISO 19085-1:2017, which gives requirements
common to different machine types.

ISO 19085-3:2017(E)
Introduction
The ISO 19085 series of International Standards provides technical safety requirements for the
design and construction of woodworking machinery. It concerns designers, manufacturers, suppliers
and importers of the machines specified in the Scope. It also includes a list of informative items to be
provided the user by the manufacturer.
This document is a type-C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requirements of this type-C standard take precedence over the requirements of
the other standards for machines that have been designed and built according to the requirements of
this type-C standard.
The full set of requirements for a particular type of woodworking machine are those given in the part
of ISO 19085 applicable to that type, together with the relevant requirements from ISO 19085-1:2017, to
the extent specified in the Scope of the applicable part of ISO 19085.
As far as possible, in parts of ISO 19085 other than ISO 19085-1:2017, safety requirements are referenced
to the relevant sections of ISO 19085-1:2017 to avoid repetition and reduce their length. The other parts
contain replacements and additions to the common requirements given in ISO 19085-1:2017.
This document is intended to be used in conjunction with ISO 19085-1:2017, which gives requirements
common to the different machine types.
Thus, Clauses 5, 6, 7 and 8, with their subclauses and the annexes of this document can either
— confirm as a whole,
— confirm with additions,
— exclude in total, or
— replace with specific text,
the corresponding subclauses or annexes of ISO 19085-1:2017.
This interrelation is indicated in the first paragraph of each clause, subclause or annex, right after the
title, by one of the following statements:
— “This subclause of ISO 19085-1:2017 applies”;
— “This subclause of ISO 19085-1:2017 applies with the following additions”, or “This subclause of
ISO 19085-1:2017 applies with the following additions, subdivided into further specific subclauses.”;
— “This subclause of ISO 19085-1:2017 does not apply.”;
— “This subclause of ISO 19085-1:2017 is replaced by the following text.”, or “This subclause of
ISO 19085-1:2017 is replaced by the following text, subdivided into further specific subclauses.”.

Specific subclauses and annexes in this document without correspondent in ISO 19085-1:2017 are
indicated by the introductory sentence: “This subclause (or annex) is specific to this document.”
Clauses 1, 2 and 4 replace the correspondent clauses of ISO 19085-1:2017, with no need for indication
since they are specific to each part of the series.

Woodworking machines — Safety requirements —
Part 3:
Numerically controlled (NC) boring and routing machines
1 Scope
This document gives the safety requirements and measures for numerically controlled (NC) boring
machines, NC routing machines and NC combined boring/routing machines (as defined in 3.1),
hereinafter referred to as "machines".
This document deals with all significant hazards, hazardous situations and events, listed in Clause 4,
relevant to the machines when they are operated, adjusted and maintained as intended and under the
conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport,
assembly, dismantling, disabling and scrapping phases have been taken into account.
NOTE For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.
This document is also applicable to machines fitted with one or more of the following devices/ additional
working units, whose hazards have been dealt with:
— additional equipment for sawing, sanding, edge banding or assembly units and dowel devices;
— fixed or movable workpiece support;
— mechanical, pneumatic, hydraulic or vacuum workpiece clamping;
— automatic tool change facilities.
Machines covered in this document are designed for workpieces consisting of
— solid wood,
— material with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2),
— gypsum boards, gypsum bounded fibreboards,
— composite materials with core consisting of polyurethane or mineral material laminated with
light alloy,
— polymer-matrix composite materials and reinforced thermoplastic/thermoset/elastomeric
materials, and
— composite boards made from the materials listed above.
This document does not deal with specific hazards related to
— edge-banding equipment fitted to the machines,
— use of grinding wheels,
— ejection from milling and/or sawing tools through openings guarded by curtains on machines where
the distance between the workpiece support surface and the lower edge of the partial enclosure
exceeds 600 mm,
— ejection due to failure of milling tools with a cutting circle diameter equal to or greater than 16 mm
and sawing tools not conforming to EN 847-1:2013 and EN 847-2:2013,
ISO 19085-3:2017(E)
— the combination of a single machine being used with other machines (as a part of a line),
— the necessity to step onto or into the machine body due to its large size, e.g. to adjust clamping
elements on machines for wooden walls, and
— integrated workpiece loading/unloading systems (e.g. robots).
This document is not applicable to single spindle hand fed or integrated fed routing machines, machines
intended for use in potentially explosive atmosphere, or to machines manufactured prior to its
publication.
