Annex ZA
(informative)
Relationship between this European Standard and
the Essential Requirements of EU Directive 2006/42/EC

This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association to provide one means of conforming to Essential Requirements of
the New Approach Directive 2006/42/EC on machinery.

Once this standard is cited in the Official Journal of the European Union under that Directive and has been
implemented as a national standard in at least one Member State, compliance with the normative clauses of
this standard confers, within the limits of the scope of this standard, a presumption of conformity with the
Essential Requirement 1.7.4.2 u) of that Directive and associated EFTA regulations.

WARNING — Other requirements and other EU Directives may be applicable to the product(s) falling
within the scope of this standard.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 22868 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 17, Manually portable forest machinery.
This second edition cancels and replaces the first edition (ISO 22868:2005), which has been technically
revised. It now also deals with pole-mounted powered pruners, hedge-trimmers and garden blowers/vacuums.

Introduction
1)
This document is a type-C standard as stated in ISO 12100.
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 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.
During the first steps in the preparation of this International Standard it became obvious that the repeatability
of the test results could become better if the operator were to be replaced by a simulation process,
representing the normal operating modes with chain-saws and trimmers/brush-cutters. Furthermore, it was
found that the cutting process performed with chain-saws causes considerable deviations, which are not
related to the measured object but to the test procedure itself.
Based on these observations, it was concluded that the operators in both test procedures, i.e. for chain-saws
and trimmers/brush-cutters, ought to be replaced by a defined fixture and the cutting process with chain-saws
by a brake simulating the load. In this manner, the
