Overview

EN ISO 19085-4:2024 - published by CEN - is the safety standard for vertical panel circular sawing machines used in continuous production. It defines safety requirements and measures for manually loaded and unloaded machines (hand feed or integrated feed) and covers operation, adjustment and maintenance under intended and reasonably foreseeable misuse. The standard also addresses transport, assembly, dismantling, disabling and scrapping phases and applies to machines fitted with common additional units (scoring, angle cutting, integrated feed, grooving with cutter ≤ 27 mm, panel pushers, supports, etc.).

Key materials in scope include solid wood, wood-like materials (see ISO 19085-1:2021), composite panels, polymer-matrix composites, gypsum boards, honeycomb aluminium and similar engineered boards. Exclusions are explicitly listed (for example machines designed to cut only vertically, machines with certain pressure-beam configurations, or machines for explosive atmospheres).

Key Topics

• Control systems and devices: safety and reliability of controls, start/stop functions, emergency stop, mode selection, manual reset, teleservice and monitoring.
• Stopping and braking: braking functions for tools, maximum run-down time, brake release and braking strategy for circular saw blades.
• Mechanical safety: stability, risk of break-up, tool-holder and spindle locking, blade fixing and flange dimensions.
• Guards and protective equipment: fixed guards, interlocking movable guards, hold-to-run and two-hand controls, and electro-sensitive protective equipment (ESPE).
• Monitoring & diagnostics: standstill detection, moving-part speed monitoring, time-delay and failure-of-power-supply requirements.
• Hazard coverage & lifecycle: addresses hazards listed in Annex A and considers transport, assembly, servicing and scrapping.
• Additional units: requirements for integrated feed devices, scoring units, angle cutting, middle supports, programmable end stops, grooving tools (≤ 27 mm), panel pushers and lowering devices.

Applications

• Machine manufacturers and designers: to design vertical panel circular sawing machines that meet modern safety requirements and support CE compliance.
• Safety engineers and compliance officers: to assess conformity with the Machinery Directive (Directive 2006/42/EC) and to apply presumption of conformity where the standard is cited (see Annex ZA).
• Production managers and procurement: to specify safe equipment for panel cutting lines and integrated feed workflows.
• Maintenance teams and trainers: to follow safe servicing, isolation and lockout procedures specified for these machines.
• Test labs and certification bodies: to evaluate guarding, braking and control-system requirements.

Related Standards

• ISO 19085 series (see ISO 19085-1:2021 for materials similar to wood)
• Machinery Directive 2006/42/EC (Annex ZA explains the relationship and presumption of conformity)

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 document 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 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, 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 (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.
The full set of requirements for a particular type of woodworking machine are those given in the part of the
ISO 19085 series applicable to that type, together with the relevant requirements from ISO 19085-1, to the
extent specified in the Scope of the applicable part of the ISO 19085 series.
As far as possible, the safety requirements of parts of the ISO 19085 series refer to the relevant subclauses
of ISO 19085-1. Each part includes replacements and additions to the common requirements given in
ISO 19085-1.
All parts of the ISO 19085 series have the same structure, so that reference to ISO 19085-1 is made always
and only from and to the same subclause number at the last indent level.
Clauses 1 to 3 are specific to each part and, therefore are distinct from ISO 19085-1:2021, Clauses 1 to 3.
For Clauses 4 to 7 and the annexes, each subclause in ISO 19085-1:2021 is cited as either:
— confirmed as a whole;
— confirmed with additions;
— excluded entirely; or
— replaced with specific text.
This is indicated by one of the following possible statements:
— “ISO 19085-1:2021, [subclause/Annex], applies”;

vi
ISO 19085-4:2024(en)
— “ISO 19085-1:2021, [subclause/Annex], applies with the following additions.” or “ISO 19085-1:2021,
[subclause/Annex], applies with the following additions, subdivided into further specific subclauses.”;
— “ISO 19085-1:2021, [subclause/Annex], does not apply.”;
— “ISO 19085-1:2021, [subclause/Annex], is replaced by the following text.” or “ISO 19085-1:2021,
[subclause/Annex], is replaced by the following text, subdivided into further specific subclauses.”.
Other subclauses and annexes specific to this document are indicated by the introductory sentence:
“Subclause/Annex specific to this document.”.
