Machinery for forestry - Safety requirements and testing for pole-mounted powered pruners - Part 1: Machines fitted with an integral combustion engine (ISO 11680-1:2021)

This document specifies safety requirements and measures for their verification for the design and
construction of portable, hand-held, pole-mounted powered pruners (hereafter named “machine”),
including extendable and telescopic machines, having an integral combustion engine as their power
source. These machines use a power transmission shaft to transmit power to a cutting attachment
consisting of a saw-chain and guide bar, a reciprocating saw blade or a single-piece circular saw blade
with a 205 mm maximum outside diameter. Methods for the elimination or reduction of hazards arising
from the use of these machines and the type of information on safe working practices to be provided by
the manufacturer are specified.
This document deals with all significant hazards, hazardous situations or hazardous events with the
exception of electric shock from contact with overhead electric lines (apart from warnings and advice
for inclusion in the instructions), relevant to these machines when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
This document is applicable to portable, hand-held, pole-mounted powered pruners manufactured after
its date of publication.
Brush cutters with a circular saw blade are not included in the scope of this document.
NOTE Brush cutter requirements are outlined in ISO 11806-1:2021.

Foreword

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).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Foreword

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).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

This third edition cancels and replaces the second edition (ISO 11680-1:2011), which has been

technically revised.
The main changes compared to the previous edition are as follows:

— 1 Scope broadened to include extended and telescopic machines and Figure 1 amended to show

different types of pole pruners

Introduction
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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11680-1:2020(E)
Machinery for forestry — Safety requirements and testing
for pole-mounted powered pruners —
Part 1:
Machines fitted with an integral combustion engine
1 Scope

This part of ISO 11680 gives safety requirements and measures for their verification for the design

and construction of portable, hand-held, pole-mounted powered pruners (hereafter named “machine”),

including extendable and telescopic machines, having an integral combustion engine as their power

source. These machines use a power transmission shaft to transmit power to a cutting attachment

consisting of a saw chain and guide bar, a reciprocating saw blade or a single-piece circular saw blade

with a 205 mm maximum outside diameter. Methods for the elimination or reduction of hazards arising

from the use of these machines and the type of information on safe working practices to be provided by

the manufacturer are specified.

This part of ISO 11680 deals with all significant hazards, hazardous situations or hazardous events

with the exception of electric shock from contact with overhead electric lines (apart from warnings and

advice for inclusion in the instructions), relevant to these machines when they are used as intended and

under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).

This part of ISO 11680 is applicable to portable, hand-held, pole-mounted powered pruners

manufactured after its date of publication.

NOTE Brush cutters with a circular saw blade are not included in the scope of this standard. Brush cutter

requirements are outlined in ISO 11806-1.
