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).

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 stated 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 (regulators, accident prevention organisations, market surveillance etc.)
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 at 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, 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 DIS 19085-1:2026 or give specific
requirements or both.

3.1
horizontal beam panel circular sawing machine
machine designed for cutting panels, fitted with one travelling saw carriage (3.4) per cutting line
incorporating one or more circular saw blades, with horizontal workpiece support and with a pressure beam
(3.5) holding the workpiece in position during cutting
Note 1 to entry: The workpiece can be mechanically positioned by a panel pusher (3.6) for the cuts. The cutting stroke
is power driven. Before the cutting stroke commences, the saw blade is automatically raised and is lowered below the
workpiece support for the return stroke. Examples are shown in Figure 1.
3.2
manual loading
operation where the operator puts the workpiece directly on the workpiece support from the front side of
the machine, or onto an intermediate loading device that cannot keep the operator away from the machine
front cutting line of at least 1 500 mm during operation
3.3
manual unloading
operation where the operator removes the workpiece directly from the workpiece support, or from an
intermediate unloading device that cannot keep the operator away from the machine front cutting line of at
least 1 500 mm during operation
3.4
saw carriage
supporting unit of the saw blades, which performs the cutting stroke

3.5
pressure beam
workpiece clamping device extending across the full working width of the machine with the function to hold
the workpiece down to the workpiece support during cutting
Note 1 to entry: The pressure beam is also part of the safeguarding of the saw blades in the cutting area.
3.6
panel pusher
movable workpiece guiding device used to position the workpiece over the line of cut, and fitted with holding
devices e.g. collets for holding the workpiece in position
Note 1 to entry: The positioning of the panel pusher can be under NC control.

cutting cycle
single cut operation consisting of vertical movements of the saw blades and horizontal movements of the
saw carriage (3.4)
3.8
rest position
position in either the left or the right side of the machine body and outside of the cutting
area to which the saw carriage (3.4) can return at the end of each cutting cycle (3.7)
3.9
rest position
position of the saw blade below the machine table

front cutting line
cutting line closest to the operator's position

head cutting line
first cutting line to divide a panel before further cuts, where the saw carriage (3.4) can be mounted below or
above the workpiece support

— for control power-on;
— for normal stop;
— for the movement of the panel pusher;
— for saw spindle speed changing;
— for the side pressure;
— for the pushing out device;
— for hold-to-run of the downward movement of the pressure beam.
Emergency stop control devices shall be provided on the main control panel, on any auxiliary control panel,
and at the following positions unless the main control panel or an auxiliary control panel is placed there

c) on the rear side of the machine without panel pusher: at both sides of the loading/unloading opening.
An additional cycle start control device may be fitted on the front side of the machine, at one of the air-
cushion tables. It shall be supplemented by a normal stop or an emergency stop control device adjacent to it.
If more than one additional control device for cycle start is provided at the air-cushion tables, only one shall
be active at a time.
The cycle start control device may be a push button or push bar (as long as cushion table maximum) and shall,
in any case, be fitted with protection means against inadvertent actuation as specified in ISO 14118:2017.
