Forestry machinery - Vibration test code for portable hand-held machines with internal combustion engine - Vibration at the handles (ISO 22867:2004, including Cor 1:2006)

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 .

Forstwirtschaftliche Maschinen - Schwingungsmessnorm für handgehaltene Maschinen mit Verbrennungsmotor - Schwingungen an den Handgriffen (ISO 22867:2004, einschließlich Cor 1:2006)

Diese Internationale Norm legt ein Schwingungsmessverfahren zur effizienten Ermittlung der Schwingungen an den Handgriffen von handgehaltenen forstwirtschaftlichen Maschinen mit Verbrennungs¬motor, wie Kettensägen, Freischneider und Grastrimmer, unter einheitlichen Bedingungen fest. Diese Messnorm dient sowohl Herstellern zur Kontrolle ihrer Erzeugnisse als auch zur Typ¬prüfung. Der Zweck besteht darin, die ermittelten Werte zum Vergleich verschiedener Maschinen oder unterschiedlicher Modelle derselben Maschinenart verwenden zu können. Obwohl die Messwerte in einem Ersatz-Arbeitsverfahren ermittelt werden, sind sie ein Maß für die Werte, die unter praktischen Arbeitsbedingungen zu finden sind.

Machines forestières - Code d'essai des vibrations pour machines portatives tenues à la main à moteur à combustion interne - Vibrations au niveau des poignées (ISO 22867:2004, Cor 1:2006 inclus)

L'ISO 22867:2004 spécifie un code d'essai vibratoire pour déterminer, avec efficacité et dans des conditions normalisées, l'amplitude des vibrations aux poignées des machines forestières portatives tenues à la main à moteur à combustion interne, telles que les scies à chaîne, les débroussailleuses et les coupe-herbe. Le code est applicable au contrôle de la production des constructeurs ainsi qu'aux essais de type. Il est prévu que les résultats obtenus puissent servir pour comparer des machines différentes ou des modèles différents du même type de machine. Bien que les grandeurs mesurées soient obtenues en fonctionnement artificiel, elles donnent cependant une indication des valeurs que l'on rencontre dans une situation de travail réelle.

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

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.

hwx hwy
and a .
hwz
The quantities to be determined are the vibration total values, a , and the equivalent vibration total values,
hv
a , for each handle. See Annexes A and B.

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.

The centre of gravity of the accelerometers shall be positioned at a maximum distance of 20 mm from the
handle contour. One of the axis of the accelerometer shall be parallel to the axis of the handle.
NOTE The specific conditions for the particular types of machines covered by this International Standard are given in
Annexes A and B.
7 Operating conditions, test procedure and presentation of results
Measurements shall be carried out on a new machine, featuring standard equipment as provided by the
manufacturer, and with the tank(s) at least half filled.
NOTE The specific conditions for the particular types of machines covered by this International Standard are given in
Annexes A and B.
The measured vibration of the machine can be influenced by the operator. The operator shall therefore be
skilled and able to operate the machine properly.
The measurement shall be continued until the validity requirement given in Clause 8 is fulfilled.
The total vibration for each handle shall be calculated in accordance with Annex A or B, as appropriate.
8 Validity test
The validity is assured for every combination of handle and operating mode, when either the coefficient of
variation, C , of the consecutive weighted values is less than 0,4 or the standard deviation, s , is less than
v n−1
2
0,4 m/s .
If the measured values for a combination of handle and operating mode exceed 0,4 for both coefficient of
variation and standard deviation, only the non-complying combination shall be repeated until the criterion of
0,4 is met.
For the purposes of this document, the coefficient of variation, C , of a test series is defined as the ratio
v
between the standard deviation, s , of a series of measurement values and the mean value, x, of the series:

10 Measurement uncertainties and declaration of vibration values
Vibration declaration is the responsibility of the manufacturer. If undertaken, it shall be done so that it is
possible to verify the declared values.
The declaration shall include a reference to this vibration test code and to the basic standard used. Deviations,
if any, from this test code and/or the basic standard shall also be indicated.
Calculated equivalent vibration values for the work cycles (see A.4.2 and B.4.2) shall be declared. The
average vibration value for idling, full load and racing (if applicable) shall be provided by the manufacturer on
request.
The uncertainties associated with the measurements shall be taken into account when deciding on the values
to be declared.
NOTE The methodology used for taking uncertainty into account needs to be based on the use of measured values
and measured values and uncertainties. The latter are the uncertainty associated to the measurement procedure (which is
determined by the grade of accuracy of the measurement method used) and the production uncertainty (variation of
vibration emission from one machine to another of the same type made by the same manufacturer). One method for the
calculation of uncertainty is given in EN 12096.
