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

ISO 19085-8:2017(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 that the
manufacturer will need to give to the user.
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, 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 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, 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.

Part 8:
Belt sanding and calibrating machines for straight
workpieces
1 Scope
This document gives the safety requirements and measures for stationary calibrating and sanding
machines, with an integrated feed and one or more sanding belt units positioned above and/or below
the work piece level, with manual or automatic loading and/or unloading, hereinafter referred to as
“machines”.
It deals with all significant hazards, hazardous situations and events as listed in Clause 4, relevant to
the 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 have been taken into account.
NOTE 1 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:
— transversal sanding unit;
— cleaning brushing unit;
— satining roller unit;
— disk brushing unit;
— texturing brushing roller unit;
— texturing brushing belt unit;
— cutterblock unit;
— texturing band saw unit;
— spiked roller unit;
— antistatic bars;
— conveyor directly controlled by the machine;
— additional work piece vacuum clamping device.
The machines are designed to calibrate and/or sand work pieces, in shape of panels or beams,
consisting of:
a) solid wood;
b) material with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2);
c) gypsum boards, gypsum bounded fibreboards;
d) composite materials with core consisting of e.g. polyurethane or mineral material;
ISO 19085-8:2017(E)
e) composite boards made from the materials listed above;
f) all materials listed above, also already lacquered.
This document does not deal with hazards related to:
— specific devices other than those listed above;
— access through in-feed and out-feed openings of machines with a work piece height capacity greater
than 550 mm;
— systems for automatic loading and/or unloading of the work piece to/from a single machine;
NOTE 2 Loading the machine manually includes manually placing the work piece onto a conveyor directly
controlled by the machine. Unloading the machine manually includes manually removing the work piece from a
conveyor directly controlled by the machine.
— interfacing of the machine with any other machine.
It is not applicable to machines intended for use in potentially explosive atmosphere and to machines
manufactured prior to the date of its publication.

eliminate or reduce the risk. This document deals with these significant hazards by defining safety
requirements and/or measures or by reference to relevant standards.
These hazards are listed in Table 1.
