ISO/FDIS 19085-1

• Abstract:

  This document gives the safety requirements and measures to reduce risks arising during operation, adjustment, maintenance, transport, assembly, dismantling, disabling and scrapping, related to woodworking machines capable of continuous production use, hereinafter referred as "machines". These safety requirements and measures are those common to most of the machines, when they are used as intended and under the conditions foreseen by the manufacturer; reasonably foreseeable misuse has been considered too. The machines are designed to process solid wood and material with similar physical characteristics to wood, with hand feed or integrated feed. This document is intended to be used in conjunction with the other parts of the ISO 19085 series, applicable to specific machine types. The extent to which all significant hazards of a specific machine type are covered is indicated in the specific part of the ISO 19085 series relevant to that machine type. The hazards covered, at least partly, by the requirements of this document, are listed in Annex A. It is not applicable to machines intended for use in potential explosive atmospheres or to machines manufactured prior to the date of its publication.

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. The ISO 19085 series is intended
for designers, manufacturers, suppliers and importers of the machines specified in the Scope of its parts.
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 organizations, 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, for example, 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, 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 the requirements given in the
part of the ISO 19085 series applicable to that type of woodworking machine, together with the requirements
from this document that are cited in the applicable part of the ISO 19085 series.
This document was developed, at its first edition, taking the requirements that are common to most
woodworking machines from pre-existing specific standards on safety of different types of woodworking
machines, which were “stand-alone” standards, i.e. not parts of a multi-parts series like the ISO 19085 series.
This document can be used as a guide when the designer has to do a full risk assessment according to
ISO 12100 and design the means for reducing the risks arising from relevant hazards for any woodworking
machine not covered by a specific part of the ISO 19085 series. As the ISO 19085 series reflects the state-of-
the-art of woodworking machinery safety, referring to any subclause of its parts can also be helpful when
searching for solutions to similar risks.
In the other parts of the ISO 19085 series, a subclause can either refer to the same subclause of this document,
or give specific requirements, or both. The specific text can be subdivided into further subclauses.
The ISO 19085 series is structured as follows:
— this document (i.e. ISO 19085-1) specifies the basic safety elements (like control devices, safeguards,
guards’ materials, most common workpiece supports and guides, etc.) and their design requirements
that are suitable to woodworking machines;
— all other parts of the ISO 19085 series specify whether the basic safety elements are required for the
relevant machine type and the requirements for their implementation on the machine.

vii
For the clearest possible reference among parts, all parts of the ISO 19085 series have exactly the same
structure of subclauses numbering and headings; each part shows all subclauses headings, even those that
are not relevant to it (stating so), in all cases where this avoids shifting the following subclauses down and
losing their numbering correspondence with this document, which can be confusing.

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. The ISO 19085 series applies tois
intended for designers, manufacturers, suppliers and importers of the machines specified in the Scope of its
parts.
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 organizations, 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, for example, 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, 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 the requirements given in the
part of the ISO 19085 series applicable to that type of woodworking machine, together with the requirements
from this document that are cited in the applicable part of the ISO 19085 series.
This document was developed, at its first edition, taking the requirements that are common to most
woodworking machines from pre-existing specific standards on safety of different types of woodworking
machines, which were “stand-alone” standards, i.e. not parts of a multi-parts series like the ISO 19085 isseries.
This document can be used as a guide when the designer has to do a full risk assessment according to ISO
12100 and design the means for reducing the risks arising from relevant hazards for any woodworking
machine not covered by a specific part of the ISO 19085 series. As the ISO 19085 series reflects the state-of-
the-art of woodworking machinery safety, referring to any subclause of its parts can also be helpful when
searching for solutions to similar risks.
In the other parts of the ISO 19085 series, a subclause can either refer to the same subclause of this document,
or give specific requirements, or both. The specific text can be subdivided into further subclauses.
viii
The ISO 19085 series is structured as follows:
— this document (i.e. ISO 19085-1) specifies the basic safety elements (like control devices, safeguards,
guards’ materials, most common workpiece supports and guides, etc.) and their design requirements that
are suitable to woodworking machines;
— all other parts of the ISO 19085 series specify whether the basic safety elements are required for the
relevant machine type and the requirements for their implementation on the machine.
For the clearest possible reference among parts, all parts of the ISO 19085 series have exactly the same frame
asstructure of subclauses numbering and headings, and; each part shows all subclauses headings, even those
that are not relevant to it (stating so), in all cases where this avoids shifting the following subclauses down
and losing their numbering correspondence with this document, which couldcan be confusing.

technology, shall be designed and implemented in accordance with ISO 13849--1:2023.
The parts of the machine control systems that are assigned to provide safety functions are called safety-related
parts of control systems (SRP/CS).
The ability of SRP/CS to perform a safety function under foreseeable conditions is allocated to one of five
levels, called performance levels (PL).
NOTE 1 The concept of PL belongs to SRP/CS: each safety function has its own PL, which can differ from those of other
safety functions. Therefore, no single PL exists forSince a machine, typically havinghas more safety functions, no single
PL exists for a machine and expressions like “machine PL” make no sense indeed.
The required performance level (PL ) for each safety function is given in the relevant subclauses of
r
Clause 4Clause 4 and Clause 5Clause 5.
Annex BAnnex B summarizes the performance levels required for all safety functions.
NOTE 2 SpecificSome parts of the ISO 19085 series can introduce further safety functions not considered in this
document or a PL different from that given in this document for the same safety function, depending on the risk
r
assessment done for the relevant machine in accordance with ISO 12100:2010.
For machines for which no specific part of the ISO 19085 series exists, if the risk assessment results in a PLr
higher than that of this document for any safety function, the higher PL shall apply.
r
Wherever PL and PL are mentioned in ISO 19085 series, their requirements refer to ISO 13849-1:2023.
r
The Safety-Related Embedded Softwaresafety-related embedded software (SRESW) of the SRP/CS shall be in
accordance with
ISO 13849-1:2023, 7.1 and 7.3.
The Safety-Related Application SoftwareThe safety-related application software (SRASW) of the SRP/CS shall
be in accordance with
ISO 13849-1:2023, 7.1 and 7.4.
A verification that the PL of each safety function and safeguard achieves the PL shall be done in accordance
r
with ISO 13849-1:2023, Clause 8.
SRP/CS shall be validated in accordance with ISO 13849-1:2023, Clause 10.
4.2 Control devices
4.2.1 General
All hand-operated control devices shall be positioned between 600 mm and 1 800 mm above floor level. For
electric control devices, see also IEC 60204--1:2016+A1:2021, 10.1.2.
It shall be possible to actuate the normal stop or emergency stop control device from the same operator
position as the start control device.
An emergency stop device shall be fitted in the vicinity ofnear the hold-to-run control device and of, near the
enabling control device and on any hand-held control set.
4.2.2 Hand-held control set
Mode selector and control devices for reset and for control power-on shall not be fitted on hand-held control
sets.
When a wireless control set loses its connection to the machine, an emergency stop shall be automatically
activated.
The SRP/CS for the emergency stop activation including the detection of connection loss, in case of wireless
control disconnection, shall achieve PL = c.
r
NOTE forThe PLr of all safety functions with control device on hand-held control sets, see are given in the relevant
subclauses.
4.2.3 Reset device
Reset devices shall be situated outside the hazard zone in a position with a good view to the hazard zone. It
shall not be possible to actuate the reset control device from inside the hazard zone.
4.3 Start
4.3.1 Direct start
Before start of the machine, all relevant safeguards shall be in place and operational. This is achieved by the
interlocking arrangements described in 4.64.6 and 5.65.6.
Start shall only be possible by actuation of the start control device provided for that purpose. Unintended
actuation shall be impeded (e.g. by a control device with shroud).
Start of powered feed (integrated or demountable) shall only be possible when the tools involved in machining
are spinning.
The SRP/CS for prevention of unexpected start shall achieve PL = c.
