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.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This third edition cancels and replaces the second edition (ISO 10517:2009), which has been technically

revised. It also incorporates the Amendment ISO 10517:2009/Amd 1:2013. The main changes compared

to the previous edition are as follows:

— the noise measurement procedure has been removed from the body of the document and has been

replaced with the reference to ISO 22868;

— the vibration measurement procedure has been removed from the body of the document and has

been replaced with the reference to ISO 22867;
— handle strength requirement has been added;

— extended-reach hedge trimmers have been better implemented in the body of the document;

— a test for the labels has been added;
— several text changes have been made for better understanding.

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 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 the 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.

Powered hand-held hedge trimmers — Safety
1 Scope

This document specifies safety requirements and measures for the verification of the design and

construction of hand-held, integrally-driven combustion engine hedge trimmers (hereafter referred to

as “hedge trimmers”) designed to be used by a single operator for trimming hedges and bushes while

utilizing one or more linear reciprocating cutter blades.

This document is also applicable to ”split-boom” type hedge trimmers and to multi-purpose machines

when configured as a hedge trimmer.

It establishes methods for the elimination or reduction of hazards arising from the use of the hedge

trimmers. In addition, it specifies the type of information to be provided by the manufacturer on safe

working practices.

This document deals with all significant hazards, hazardous situations and events relevant to powered

hand-held hedge trimmers when they are used as intended and under the conditions of misuse that are

reasonably foreseeable by the manufacturer (see Clause 4).

This document is not applicable to hedge trimmers with an engine displacement over 80 cm , nor is it

applicable to hedge trimmers manufactured before the date of its publication.
