Overview

EN ISO 19085-2:2021 - "Woodworking machines - Safety - Part 2: Horizontal beam panel circular sawing machines" is a CEN-adopted ISO standard that defines safety requirements and protective measures for horizontal beam panel circular saws used for continuous production. It covers machines with the saw carriage of the front cutting line mounted below the workpiece support, including manually and/or powered loading and manual unloading. The standard addresses significant hazards during operation, adjustment, maintenance, transport, assembly, dismantling, disabling and scrapping, and includes a detailed list of additional working units and devices whose hazards are treated.

Key scope points

• Applies to machines processing panels made of wood and wood-like materials, gypsum boards, composites, cardboard, foam board, mineral boards, polymer-matrix composites and aluminium (up to 10 mm), among others.
• Lists many optional units (e.g., scoring units, panel turners, powered loaders, vacuum clamping, additional cutting lines, saw blade cooling systems).
• Identifies specific exclusions (see standard text), and refers to Annex A for the list of significant hazards considered.

Key Topics

The standard organizes safety requirements across control, mechanical and other hazard domains. Major technical topics include:

• Control systems and operator interfaces (Clauses 4.x): reliability, mode selection, start/stop logic, emergency stop, manual reset, standstill detection and teleservice.
• Braking and run-down times (5.4): tool braking performance and maximum run-down times to reduce kick-back and contact risk.
• Tool and spindle safety (5.3): tool fixing, flange dimensions, spindle locking and risk of tool break-up.
• Guards and protective devices (5.5): fixed guards, interlocking movable guards, hold‑to‑run/two‑hand controls, electro‑sensitive and pressure‑sensitive protective equipment.
• Stability, mechanical strength and ejection hazards (5.1–5.3): machine stability, prevention of ejected objects and break-up risks.
• Electrical, energy isolation and auxiliary hazards (Clause 6): supply failure, static electricity, noise, emissions and fire prevention.
• Information and documentation (Clause 7): marking, warnings, instructions and maintenance guidance.
• Harmonization with EU machinery law: Annex ZA maps clauses to Directive 2006/42/EC essential requirements for CE presumption of conformity.

Applications

This standard is essential for:

• Machine manufacturers and designers developing horizontal beam panel saws to meet safety and regulatory requirements.
• Safety and compliance engineers performing risk assessments and preparing CE technical documentation.
• Maintenance and plant managers who define safe servicing, isolation and lockout procedures.
• Purchasing teams and testing labs validating machine safety features and conformity.
• Operators and trainers using the standard’s guidance to inform safe operation and training materials.

Related Standards

• ISO 19085‑1 (general safety principles for woodworking machines)
• Other parts of ISO 19085 for specific machine types and additional safety topics

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.

Introduction
The ISO 19085 series 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 to be provided to the user by
the manufacturer.
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.
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, to the
extent specified in the Scope of the applicable part of ISO 19085.
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 contains replacements and additions to the common requirements
given in ISO 19085-1.
Clauses 1 to 3 are specific to each part and, therefore, replace ISO 19085-1:2021, Clauses 1 to 3.
For Clauses 4 to 7 and the annexes, ISO 19085-1:2021, Clauses 4 to 7 and Annexes, each subclause can
be:
— confirmed as a whole;
— confirmed with additions;
— excluded in total; or
— replaced with specific text.
This is indicated by one of the following possible statements:
— “ISO 19085-1:2021, [subclause/Annex], applies”;
vi
ISO 19085-2:2021(E)
— “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.”.
