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.

Different types of the AIMS defined in 3.4 are patented. However, they are not required to be installed nor described in detail: subclauses 5.6.7, 5.6.8, 5.12 just gives some requirements for their implementation on the machine.

Woodworking machines — Safety — Part 5: Dimension saws

This document specifies the safety requirements and measures for dimension saws (defined in 3.1), capable of continuous production use and hereinafter referred to also as “machines”.

The machines are designed to cut solid wood and material with similar physical characteristics to wood.

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. Transport, assembly, adjustment, maintenance, dismantling, disabling and scrapping phases have also been taken into account.

This document is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with:

a) device to raise and lower the main saw blade and scoring saw blade;

b) device to tilt the main saw blade and scoring saw blade for angled cutting in one or both directions;

c) device for scoring;

d) device for grooving with milling tool with a width not exceeding 20 mm;

e) demountable power feed unit;

f) power-operated sliding table;

g) workpiece clamping.

This document provides basic (not all) safety requirements for integration of Active Injury Mitigation System (AIMS) in the machine provided with an AIMS, but not the requirements of AIMS itself, and gives guidance on the design and risk assessment of AIMS.

This document is not applicable to machines intended for use in potentially explosive atmospheres or to machines manufactured prior to the date of its publication.

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

   Guidance on the design of the machine with AIMS
   1. General

AIMS shall always have a functionality that is suitable or adapted to the respective machine and its application. The hazards and operating situations of the machine and the performance and use limits of the AIMS shall be taken into account during the risk assessment to be made in accordance with ISO 12100.

The operation, functionality and limits of AIMS shall be clearly disclosed to the user.

The trust of the user is decisive for acceptance in the use of an AIMS. The use of an AIMS shall not impair the functionality of the machine to such an extent that it leads to a lack of usability or loss of trust and acceptance.

The reasonably foreseeable use of the machine shall be taken into account when designing the AIMS.

If the AIMS has a configuration option, e.g. for the parameterization of product characteristics by the service personnel, a management system for the authorizations of persons or groups of persons shall be installed. If the AIMS has facilities to make user-specific settings, these shall be stored on a personal basis and easily retrievable by any user and easily reset.

AIMS may be bypassed by the user. The bypass of an AIMS function shall be continuously indicated e.g. by a signal device.

In order to detect and signal failures that do not automatically reveal themselves to the user, AIMS shall be equipped with automatically executed diagnostic measures for the detection and signalling of failures that are appropriate to the function of the AIMS. This shall be done taking into account the requirements for functional safety, e.g. based on ISO 13849-1.

• 1. Tampering

AIMS shall be designed, integrated and usable in such a way that incentives for operators to carry out foreseeable tampering are considered.

Tampering should be detected by the AIMS as far as reasonably feasible and this should be displayed or the machine should enter a safe state.

• 1. Human-machine interface, ergonomic requirements

The human-machine interface shall be adapted in a suitable way to the defined usage requirements. The design of the interfaces shall meet ergonomic requirements.

AIMS shall provide users with relevant information in a timely and ergonomic manner so that they can reliably perceive and process it and react to all information in a timely manner.

Principles of ergonomics shall be applied both with regard to the design of AIMS, and to their use with the machine. This means, for example, that:

— the design requirements of ergonomics with regard to the arrangement of displays are met;

— primary information for task processing is recognizably displayed in the user's central field of view;

— the control elements for task processing can be arranged in the user's working area

— All displays shall take into account ergonomic design requirements in terms of character height, colour spectrum, sound spectrum and perception thresholds for the human sensory systems.

— The user concept of the AIMS shall not cause any unnecessary additional impairment of the user's information processing or tie up the user's attention for other tasks.

Current information on the operating status and functionality shall be displayed in such a way that it can be reliably recognized by the user from the working position.

The use of AIMS shall not result in any impairments or hazards for users or indirectly affected persons.

The signal design should take into account proximity to the hazard, where applicable.

Controlling the AIMS shall follow simple and logical procedures.

The visible, acoustic and haptic signals of the AIMS shall be designed to suit the environmental conditions (e.g. noise, lighting conditions) and be clearly perceptible to the user.

• 1. Specific information for use

The user information on the intended use of the AIMS includes the specified operating and hazardous situations.

Performance and usage limits and the handling of the AIMS shall be made clearly transparent, for example via the human-machine interface or by means of suitable accompanying information.

The operating instructions of AIMS shall contain sufficient and appropriate information and instructions for the use of the AIMS, focusing on the instruction of contents specific to the AIMS. This includes addressing any necessary health condition.

   Guidance on the testing of the machine with AIMS
   1. General

Since this test principle can be used to test a variety of types of AIMS, no specific test setup can be defined or specified.

The test setup is determined using the manufacturer's risk assessment as the basis.

Testing shall be carried out on the machine with AIMS installed, under defined environmental conditions.

The test focuses on the functionality and reliability of the AIMS.

A test plan shall be setup and the depth of inspection depends on the design of the AIMS.

• 1. Documentation for testing

The technical documentation includes the following documents (if applicable):

— a general description of the AIMS (including its design and functioning, intended use and operating environment),

— accompanying information,

— Block diagram and/or connection diagram,

— Functional safety documents (e.g. FMEA, description of the diagnostic measures).

• 1. Environmental conditions

The test shall be carried out in the same environmental conditions as the normal operation of the machine. The effectiveness is tested on the basis of essential parameters (e.g. reaction times, etc.).

The exact data is determined and recorded.

The technical specifications of the manufacturer and the system limits specified in the operating instructions shall be checked for plausibility with regard to the application requirements.

Other technical specifications of the manufacturer on environmental conditions (see also information in the operating instructions), are not part of the test of the AIMS.

• 1. Test specimen

Test specimens are aids to be able to simulate the human body parts, depending on the physical principle of functioning of the AIMS.

Test specimens are determined on the basis of the use cases of the AIMS.

Test specimens shall be designed for the AIMS to be tested and described in the test report.

• 1. Reliability test

The AIMS shall be tested for reliability.

A reliability test should primarily relate to the effectiveness of the intended function and to the failure of the AIMS.

In order to evaluate the reliability of the intended function, individual test criteria and test procedures shall be established, for example endurance testing, determination of the detection rates of the sensor technology, number of repetitions and environmental conditions to be tested.

Possible sufficient tests for functional safety are, for example:

— Testing

— Analysis of technical documentation,

— Evaluation of evidence of tests or records that have already been carried out,

— Evidence from a testing body.

Fault resistance, if applicable, and fault detection shall be tested. In particular, the following shall be tested:

— fault tolerance in the user interface in the operating environment,

— reasonably foreseeable types of failure,

— behaviour in fault conditions,

— behaviour in the event of misuse,

— indicators that the system is ready for operation.

• 1. Test report

The test report shall give at least the following information:

a) the date and place of the test;

b) name of the testing institute and the applicant identification if relevant;

c) the description of the machine tested, and of the AIMS;

d) the saw blades used, and the workpieces if any;

e) the machine settings;

f) the environmental conditions;

g) the test specimen;

h) the approach speed and direction;

i) the test results;

j) a reference to this document (i.e. ISO 19085-5:2026).
