Forstwirtschaftliche Maschinen - Geräuschmessnorm für handgehaltene Maschinen mit Verbrennungsmotor - Verfahren der Genauigkeitsklasse 2 (ISO 22868:2005)
Diese Internationale Norm legt ein Geräuschmessverfahren fest zur effizienten Ermittlung der Geräuschemission von handgehaltenen forstwirtschaftlichen Maschinen mit Verbrennungsmotor, wie Kettensägen, Freischneider und Grastrimmer, unter einheitlichen Bedingungen. Die ermittelten Geräuschemissions-Kennwerte sind der A bewertete Emissions-Schalldruckpegel am Ort der Bedienungsperson und der A bewertete Schallleistungspegel. Diese Messnorm dient sowohl Herstellern zur Kontrolle ihrer Erzeugnisse als auch zur Typprüfung. Der Zweck besteht darin, die ermittelten Werte zum Vergleich verschiedener Maschinen oder unterschiedlicher Modelle derselben Maschinenart verwenden zu können. Obwohl die Geräuschemissionswerte in einem Ersatz-Arbeitsverfahren ermittelt werden, sind sie für die Geräuschemission unter praktischen Arbeitsbedingungen repräsentativ.

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 first edition of ISO 22868 cancels and replaces ISO 7182:1984, ISO 7917:1987, ISO 9207:1995 and
ISO 10884:1995, of which it constitutes a technical revision.

Introduction
During the first steps in the revision 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 operating conditions during measurement would simulate
normal operating conditions.
The determination of noise emission characteristics is primarily used for
manufacturers' declarations of noise emitted,
comparing the noise emitted by machines in the family concerned, and
purposes of noise control at source at the design stage.
The use of this noise test code will ensure reproducibility of the determination of the noise emission
characteristics within specified limits determined by the grade of accuracy of the basic noise measurement
method used. Noise measurement methods allowed by this International Standard give results with Grade 2
accuracy.
The operating modes are of interest for assessment of the exposure sound pressure levels, for example, over
a typical working day.
The work cycles chosen for this test code are based on the following considerations of application:
a) chain-saws with an engine of < 80 cm are used for various operations, including felling, bucking and
delimbing;
b) chain-saws with an engine of W 80 cm are normally used for felling and bucking.
Delimbing will cause the saw to run at racing speed; therefore, racing is included only for saws with a
< 80 cm engine.
