Diese Internationale Norm legt Verfahren für die Verifizierung von Pendelschlagwerken (Prüfmaschinen) zur
Anwendung für den Charpy-Schlagversuch, Izod-Schlagversuch und Schlagzugversuch, die in ISO 179-1,
ISO 180 bzw. ISO 8256 beschrieben sind, fest.
Die von dieser Internationalen Norm berücksichtigten Prüfmaschinen sind vom Pendeltyp. Die beim Schlagen
eines Probekörpers aufgenommene Schlagenergie W (siehe 3.12) wird als gleich der Differenz zwischen der
potentiellen Energie (siehe 3.13) des Pendels und der nach dem Schlagen des Probekörpers im Pendel ver-bleibenden
Energie angesehen. Die Schlagenergie wird hinsichtlich Reibungs- und Luftwiderstandsverlusten
korrigiert (siehe Tabelle 2 und 5.6).
Es werden Verfahren zur Verifizierung der geometrischen und physikalischen Eigenschaften der
verschiedenen Teile der Prüfmaschine beschrieben. Die Verifizierung einiger geometrischer Eigenschaften ist
an der zusammengebauten Prüfmaschine schwierig auszuführen. Es wird daher angenommen, dass der
Hersteller für die Verifizierung derartiger Eigenschaften und für die Bereitstellung von Bezugsebenen an der
Prüfmaschine, die eine ordnungsgemäße Verifizierung nach dieser Internationalen Norm ermöglichen, verant-wortlich
ist.
Diese Verfahren sind für die Anwendung vorgesehen, wenn die Prüfmaschine installiert wird, instand gesetzt
wird, bewegt wurde oder einer regelmäßigen Überprüfung unterzogen wird.
Diese Internationale Norm gilt für Prüfmaschinen vom Pendelschlagtyp mit unterschiedlichen Kapazitäten
(Schlagenergien) und/oder Konstruktionen und den in Abschnitt 5 definierten geometrischen und physika-lischen
Eigenschaften.
Ein nach dieser Internationalen Norm verifiziertes und als zufrieden stellend beurteiltes Pendelschlagwerk
wird für Schlagzähigkeitsprüfungen mit gekerbten und ungekerbten Probekörpern unterschiedlicher Arten als
geeignet angesehen.

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 3.
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.
International Standard ISO 13802 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2,
Mechanical properties.
Annexes A to E of this International Standard are for information only.

INTERNATIONAL STANDARD © ISO ISO 13802:1999(E)
Plastics — Verification of pendulum impact-testing
machines — Charpy, Izod and tensile impact-testing
1 Scope
This International Standard specifies methods for the verification of pendulum impact-testing machines used for the
Charpy impact test, Izod impact test and tensile impact test described in ISO 179-1, ISO 180 and ISO 8256,
respectively.
The test machines covered by this International Standard are of the pendulum type. The impact energy W (see
3.12) absorbed in impacting a test specimen is taken as being equal to the difference between the potential energy
E (see 3.11) of the pendulum and the energy remaining in the pendulum after impacting the specimen. The impact
energy is corrected for friction and air-resistance losses (see Table 2 and 5.6).
Methods are described for verification of the geometrical and physical properties of the different parts of the test
machine. The verification of some geometrical properties is difficult to perform on the assembled instrument. It is
therefore assumed that the manufacturer is responsible for the verification of such properties and for providing
reference planes on the instrument that enable proper verification in accordance with this International Standard.
These methods are for use when the machine is being installed, is being repaired, has been moved or is
undergoing periodic checking.
This International Standard is applicable to pendulum-type impact-testing machines, of different capacities and/or
designs, with the geometrical and physical properties defined in clause 5.
A pendulum impact-testing machine verified in accordance with this International Standard, and assessed as
satisfactory, is considered suitable for impact testing with unnotched and notched test specimens of different types.
Annex A describes the relationships between the various characteristic pendulum lengths, the potential energy and
the moment of inertia of the pendulum.
Annex B explains how to calculate the ratio of frame mass to pendulum mass required to avoid errors in the impact
energy.
Annex C describes, for Charpy impact testing, the changes in pendulum velocity just after impact as a function of
impact energy and gives the ranges of impact energies for the measurement of which pendulums of specified
capacity have to be used.
Annex D discusses the stiffness of the base of the frame necessary to avoid resonant oscillations in the frame due
to reaction forces caused by the moving pendulum.
Annex E gives the dimensions of a gauge plate suitable for the verification of Charpy impact-testing machines.

measuring instrument or measuring system and values corresponding to appropriate standards or known values
derived from standards

oscillation of less that 5° to each side of the vertical
3.4

axis of rotation of the pendulum
3.5
pendulum length
L
P
distance, expressed in metres, between the axis of rotation of the pendulum and the centre of percussion (3.4); it is
