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 22867 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 cancels and replaces ISO 7505:1986 and ISO 7916:1989, of which it constitutes a technical
revision.

Introduction
The determination of vibration characteristics is primarily used for
 manufacturer's declarations,
 comparing the data between machines in the family concerned,
 development work at the design stage, and
 the estimation of the vibration risk considering the specific conditions (parameters).
The use of this vibration test code will ensure reproducibility of the determination of the vibration
characteristics.
The operating modes are of interest for assessment of the vibration exposure, for example, over a typical
working day.
The work cycles chosen for this test code are based on the following considerations of application:
3
a) chain-saws with an engine displacement of < 80 cm are used for various operations, including felling,
bucking and delimbing;
3
b) chain-saws with an engine displacement 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
3
< 80 cm engine.
For brush-cutters and grass-trimmers, the cutting mode (full load) is estimated to be valid only for short
periods, while racing and idling are the two dominant modes. Moreover, it has also been found to be diverse
and not able to be performed under repeatable conditions.
For trimmers, the full load and the racing modes are integrated in one single mode due to the loading effect of
the flexible line.
For brush-cutters, it is not possible to simulate the full load mode in a feasible way since there are no constant
load conditions comparable to chain-saws. Since the operating mode “racing” is anyhow the worst case, it is
used as representative.
In either case, transport and other tasks between operations will cause the machine to run at idling.
Experience has lead to the conclusion that equal duration for the different working modes is a good estimation
of daily exposure.

INTERNATIONAL STANDARD ISO 22867:2004(E)

Forestry machinery — Vibration test code for portable
hand-held machines with internal combustion engine —
Vibration at the handles
CAUTION — Some of the tests specified in this International Standard involve processes that could
lead to a hazardous situation. Any person performing tests in accordance with this International
Standard shall be appropriately trained in the type of work to be carried out. All national regulatory
conditions and health and safety requirements shall be followed.
1 Scope
This International Standard specifies a vibration test code for determining, efficiently and under standardized
conditions, the magnitude of vibration at the handles of portable hand-held, internal-combustion-engine-
powered forestry machines such as chain-saws, brush-cutters and grass-trimmers. The code is applicable to
manufacturer's product controls as well as type tests. It is intended that the results obtained will be able to be
used to compare different machines or different models of the same type of machine. Although the
magnitudes measured are obtained in an artificial operation, they nevertheless give an indication of the values
to be found in a real work situation.

5 Instrumentation
5.1 General
The vibration measurement system including frequency weighting for hand–arm shall be in accordance with
ISO 8041.
5.2 Accelerometer
The total mass of the vibration accelerometer giving the acceleration in the three directions at each measuring
position shall be as low as possible, and shall not in any case exceed 25 g, including the mounting but
excluding the cable. For further information see ISO 5349-2:2001, 6.1.5.
NOTE The sensitive element intended to pick up the vibration and to convert it into electrical signals is an
accelerometer. A tri-axial accelerometer will permit measurements in the x, y and z axes, simultaneously.
5.3 Fastening of accelerometer
The accelerometer and the mechanical filter, if used, shall be mounted firmly on the handle by means of a
fastening device. Guidance is given in ISO 5348 and ISO 5349-2.
For measurement on handles with resilient covers (for example, a cushioned handle), it is permissible to use a
suitable adaptor for the accelerometer. The adaptor shall consist of a suitable, formed, light, rigid plate with a
suitable mounting arrangement for the accelerometer used. Care shall be taken that the mass, size and shape
of the adaptor do not significantly influence the signal from the accelerometer in the frequency range of
interest. For more information, see ISO 5349-2:2001, 6.1.4.2.
5.4 Calibration
The whole measuring chain, including the accelerometer, shall be checked before and after use and — when
necessary — to ensure accuracy during any sequence of measurements, in accordance with ISO 8041.The
accelerometers shall be calibrated in accordance with ISO 5347 and ISO 16063.
5.5 Speed indicator
The rotational frequency of the engine shall be measured with an accuracy of ± 1,5 % of the reading. The
speed indicator and its engagement with the machine shall not affect the operation during the test.
6 Measurement direction and location
Measurements shall be made at each hand-grip, where the operator normally holds the machine.
Measurements shall be made in the three directions x, y and z.
