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 second edition cancels and replaces the first edition (ISO 22867:2004), which has been technically
revised. The scope has been expanded to include hand-held garden equipment. It also incorporates Technical
Corrigendum ISO 22867:2004/Cor 1:2006.

Introduction
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.
The vibration test code specified in this International Standard is based on ISO 20643, which gives general
specifications for the measurement of the vibration emission of hand-held machinery. It differs from ISO 20643
in the number of operators required to be involved in the test, with ISO 20643 requiring at least three operators
and this International Standard only one. Another difference is that this International Standard primarily
positions the transducers next to the hand in the area between the thumb and the index finger, where they
present the least disturbance to the operator gripping the machine.
The determination of vibration characteristics is primarily used for
— manufacturer’s declarations,
— comparing data between machines in the machine 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.
Measurements made during particular 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 ≥ 80 cm are normally used for felling and bucking.
3
Delimbing will cause the saw to run at racing speed; therefore, racing is included only for saws with a < 80 cm
engine.
For brush-cutters, grass-trimmers, hedge-trimmers and pole-mounted powered pruners, the cutting mode
(full load) is estimated to be valid only for short periods, and racing and idling are the two dominant modes.
Moreover, the cutting mode has also been found to be diverse and not able to be performed under repeatable
conditions.
For trimmers, the full-load and racing modes are integrated into a single mode, owing to the loading effect of
the flexible line.
For brush-cutters, hedge-trimmers and pole-mounted powered pruners, it is not possible to simulate the full-load
mode in a feasible way, since there are no constant load conditions comparable to those of chain-saws. Since
the operating mode “racing” is the worst case, it is taken as being representative.
For garden-blowers, full load and idling are the two dominant modes.
In either of these cases, transport and other tasks between operations will cause the machine to run at idling.
Experience has led to the conclusion that equal duration for the different working modes is a good estimation
of daily exposure. The values obtained are values intended to be representative of the average of typical
vibration magnitudes in real-world use of the machines. However, the actual magnitudes will vary considerably
from time to time and will depend on many factors, including operator, task and cutting attachment. The state
of maintenance of the machine itself might also be of importance.

INTERNATIONAL STANDARD ISO 22867:2011(E)
Forestry and gardening machinery — Vibration test code
for portable hand-held machines with internal combustion
engine — Vibration at the handles
CAUTION — Some of the test procedure specified in this International Standard involves 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 forest and garden machinery, including chain-saws (with the exception of high-handled chain-saws),
brush-cutters, grass-trimmers, pole-mounted powered pruners, hedge-trimmers and garden-blowers.
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 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 accelerometer is a sensitive element intended to pick up the vibration and to convert it into electrical
signals. A tri-axial accelerometer will permit simultaneous measurements in the �, � and � axes.
5.3 Fastening of accelerometer
The accelerometer shall be mounted firmly on the handle by means of a fastening device, in accordance with
ISO 5349-2.
For measurement on handles with resilient covers (e.g. cushioned handle), mount the accelerometer in
accordance with ISO 5349-2:2001, 6.1.4.2, and perform one or the other of the following actions:
— remove the resilient material from the area beneath the transducers;
— fix the transducers using a force which fully compresses the resilient material.
Mountings shall be in accordance with ISO 5349-2:2001, D.2.2 and D.2.3; the method given in ISO 5349-2:2001,
D.2.4, shall not be used.
5.4 Calibration
The accelerometer shall be calibrated in accordance with ISO 16063.
The whole measuring chain, including the accelerometer, shall be checked before and after a sequence of
measurements using a calibrator which produces known accelerations at a known frequency. These in‑situ
checks shall be carried out in accordance with ISO 8041.
5.5 Speed indicator
The rotational frequency of the engine shall be measured with an accuracy of ±1,0 % of the reading. The speed
indicator and its engagement with the machine shall not affect the operation of the machine under test.
6 Measurement direction and location
Measurements shall be made at each hand-grip at which the operator normally holds the machine. Measurements
shall be made simultaneously in the three directions �, � and �.
The centre of gravity of the accelerometer shall be positioned at a maximum distance of 20 mm from the handle
contour. One of the axes of the accelerometer shall be parallel to the axis of the handle.

SIST EN ISO 22867:2012
ISO 22867:2011(E)
The position of the accelerometer shall be as near as possible to the hand without obstructing normal grip.
NOTE The specific conditions for each type of machine are given in Annexes A to E.
7 Test and operating conditions of machine
Measurements shall be carried out on a new machine, featuring standard equipment as provided by the
manufacturer, and with the fuel and oil tank(s) at least half-filled.
The engine shall be run-in prior to the test according to the manufacturer’s recommendations. The engine shall
be at a stable normal operating temperature before the test is commenced.
The carburettor shall be set, where applicable, according to the instructions of the manufacturer.
The engine speed for all test modes shall be kept constant to within ±3,5 r/s during testing. No alteration to the
initial settings is permitted once measurements have commenced. If adjustment becomes necessary, the test
shall be restarted after the adjustment.
The measured vibration of the machine is influenced by the operator. The operator shall therefore be skilled
and able to operate the machine properly. The machine shall be held in a manner consistent with day-long use
of the machine. Hand-held machines, except those suspended by harness, shall be held so that there is no
contact with the operator’s body during measurements.
A test to obtain the required data for a given operating mode shall consist of a minimum of four measurements,
with a short break and a significant change (at least 20 %) of engine speed between measurements. Stable
speed conditions (constant to within ±3,5 r/s) shall be obtained before testing is continued.
At least four separate periods of vibration data shall be obtained, totalling at least 20 s.
The measurements shall be continued until the validity requirements given in Clause 8 are fulfilled.
Each signal duration used shall be at least 2 s, during which the engine speed shall be maintained within
±3,5 r/s.
The collection of data for the different operating modes need not be carried out in any particular sequence.
NOTE The specific conditions for each type of machine are given in Annexes A to E.
8 Measurement and calculation
8.1 General
The following measurements and calculations shall be made and are generally performed in the sequence
given here and as illustrated by Figure 1.
