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

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, which gives requirements
common to different machine types.

ISO 19085-4:2018(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 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 19085-1:2017, 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.
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 subclause or annex right after the title by
one of the following possible 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: “Subclause (or Annex) specific to this part of ISO 19085.”.
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.
NOTE Requirements for tools are given in EN 847-1:2013.

Woodworking machines — Safety —
Part 4:
Vertical panel circular sawing machines
1 Scope
This document gives the safety requirements and measures for manually loaded and unloaded
stationary vertical panel sawing machines, hereinafter referred to as “machines”.
NOTE 1 In manual loading, the operator puts the work-piece directly onto the work-piece support, with no
intermediate loading device to receive and transfer the work-piece from the operator to the cutting position.
In manual unloading, the operator removes the work-piece directly from the work-piece support, with no
intermediate unloading device to transfer the work-piece from the cutting position to the operator.
It deals with all significant hazards, hazardous situations and events as listed in Clause 4 relevant to
machines, when 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 are taken into account.
NOTE 2 For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.
It is also applicable to machines fitted with one or more of the following devices/additional working
units, whose hazards have been dealt with:
— an integrated feed device;
— a device for scoring;
— an angle cutting device;
— a middle support device;
— programmable end stops for parallel vertical cuts;
— a device for grooving with a width of at most 20 mm in one pass by using a milling tool; and
— a panel pusher.
The machines are designed for cutting panels consisting of:
a) solid wood;
b) material with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2);
c) composite materials with core consisting, for example, of polyurethane or mineral material
laminated with light alloy;
d) polymer-matrix composite materials and reinforced thermoplastic/thermoset/elastomeric
materials; and
e) gypsum boards, gypsum bounded fibreboards.
This document does not apply to machines
— with pressure beam and saw unit mounted behind the work-piece support;
ISO 19085-4:2018(E)
— where the guide rails on which the saw unit moves vertically are fixed on the machine frame and the
horizontal cut can only be made by manually feeding the panel;
— designed to cut in vertical direction only;
— which are displaceable;
— automatically performing two or more cutting cycles in sequence;
— intended for use in potentially explosive atmosphere; and
— manufactured before the date of its publication.
