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.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

URL: www .iso .org/ iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 4,

Woodworking machines.

This document is intended to be used in conjunction with ISO 19085-1:2020, which gives requirements

common to different machine types.
A list of all parts in the ISO 19085 series can be found on the ISO website.

This second edition cancels and replaces the first edition (ISO 19085-3:2017), which has been

technically revised.
The main changes compared to the previous edition are as follows:

— In Scope, machines are “intended for continuous production use”, in line with part-1, ed.2;

— the list of significant hazards is moved to an Annex, according to ISO-CEN rules. Following Clauses

and Annexes are renumbered accordingly;

— the structure was simplified, thanks to simplifications in part-1, ed.2; in particular, 6.6;

— the machines designs covered were clarified, and the relevant requirements were made more explicit

(and stricter in some cases) for each design in new 6.6.2, with examples figures in new Annex;

— the example solutions in 6.6.3 were improved and simplified;

— 7.2 is new, and a new updated full Noise Test Code is in Annex F, with reference to part-1, ed.2.

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 to 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.

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, 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, safety requirements are referenced

to the relevant sections of ISO 19085-1, to avoid repetition and reduce their length. The other parts

contain replacements and additions to the common requirements given in ISO 19085-1.

Thus, Clauses 4, 5, 6, and 7 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.

This interrelation is indicated in the first paragraph of each subclause or annex right after the title by

one of the following possible statements:
— “ISO 19085-1:2020, [subclause/Annex], applies”;

— “ISO 19085-1:2020, [subclause/Annex], applies with the following additions.” or “ISO 19085-1:2020,

[subclause/Annex], applies with the following additions, subdivided into further specific subclauses.”;

— “ISO 19085-1:2020, [subclause/Annex], does not apply.”;

— “ISO 19085-1:2020, [subclause/Annex], is replaced by the following text.” or “ISO 19085-1:2020,

[subclause/Annex], is replaced by the following text, subdivided into further specific subclauses.”.

Specific subclauses and annexes in this document without correspondent in ISO 19085-1:2020 are

indicated by the introductory sentence: “Subclause/Annex specific to this document.”.

Clauses 1 and 2 replace the correspondent clauses of ISO 19085-1, with no need for indication since they

are specific to each part of the series.

Woodworking machines — Safety —
Part 3:
Numerically controlled (NC/CNC) boring and routing
machines
1 Scope

This document gives the safety requirements and measures for numerically controlled (NC/CNC) boring

machines, NC/CNC routing machines and NC/CNC combined boring/routing machines (as defined in 3.2

and 3.3), designed for continuous production use, hereinafter referred to as "machines".

This document deals with all significant hazards, hazardous situations and events, listed in Annex A,

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.

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 working units for sawing, sanding, edge banding, assembling or dowel inserting;

— fixed or movable workpiece support;
— mechanical, pneumatic, hydraulic or vacuum workpiece clamping;
— automatic tool change devices.
Machines covered in this document are designed for workpieces consisting of
— solid wood,

— material with similar physical characteristics to wood (see ISO/DIS 19085-1:2020, 3.2),

— gypsum boards, gypsum bounded fibreboards, cardboard,
— matrix engineered mineral boards, silicate boards,

— composite materials with core consisting of polyurethane or mineral material laminated with

light alloy,

— polymer-matrix composite materials and reinforced thermoplastic/thermoset/elastomeric

materials,
— aluminiu
