e)       composite boards made from the materials listed above;
f)         all materials listed above, 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 700 mm;
—     systems for powered loading or unloading, or both, of the workpiece to or from a single machine;
NOTE 2        Loading the machine manually includes manually placing the workpiece onto a conveyor directly controlled by the machine. Unloading the machine manually includes manually removing the workpiece from a conveyor directly controlled by the machine.
—     out-feed workpieces on machines with feed speed higher than 60 m/min;

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

Introduction
The ISO 19085 series provides technical safety requirements for the design and construction of
woodworking machinery, as well as for the content of the relevant instruction handbook. It concerns
designers, manufacturers, suppliers and importers of the machines specified in the Scope.
This document is a type-C standard as defined in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (e.g. regulators, accident prevention organisations, market surveillance).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
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 (as defined in ISO 12100), 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.
In this document, a subclause can refer to the same subclause of ISO 19085-1:2026 or give specific
requirements or both.

This document specifies the safety requirements and measures for wide belt sanding machines (defined
in 3.1) and for surface treating machines (defined in 3.2) capable of continuous production use, altogether
referred to as “machines”.
This document deals with all significant hazards, hazardous situations or hazardous events, listed in
Annex A, relevant to the machines when used as intended and under conditions of misuse which are
reasonably foreseeable, as well as when transported, assembled, adjusted, maintened, dismantling, disabled
and scrapped.
The machines are designed to process workpieces with flat surface and even thickness, in shape of panels or
beams or frames, consisting of:
— solid wood;
— material with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2);
— gypsum boards, gypsum bounded fibreboards;
— composite materials with core consisting of, e.g. polyurethane or mineral material;
— rock wool and glass wool;
— polymer-matrix composite materials and reinforced thermoplastic, thermoset and elastomeric materials;
— expanded polystyrene (EPS) or extruded polystyrene (XPS);
— graphite;
— carbon fiber;
— matrix engineered mineral boards, silicate boards;
— composite boards made from the materials listed above;
— all materials listed above, already lacquered.
This document is also applicable to machines fitted with one or more of the following devices or 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;

ISO/DIS 19085-8:2026(en)
— cutterblock unit;
— texturing band saw unit;
— spiked roller unit;
— multi blade unit;
— conveyor directly controlled by the machine;
— additional workpiece vacuum clamping device
— laser surface treating unit;
— antistatic bar unit.
NOTE 1 An antistatic bar is a device that eliminates electrostatic charges on the workpiece to ease its subsequent
cleaning from dust by airflow.
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
700 mm;
— systems for powered loading or unloading, or both, of the workpiece to or from a single machine;
NOTE 2 Loading the machine manually includes manually placing the workpiece onto a conveyor directly
controlled by the machine. Unloading the machine manually includes manually removing the workpiece from a
conveyor directly controlled by the machine.
— out-feed workpieces on machines with feed speed higher than 60 m/min;
— interfacing of the machine with any other machine.
This document is not applicable to machines intended for use in a potentially explosive atmosphere and to
machines manufactured prior to the date of its publication.
