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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical
properties.
This second edition cancels and replaces the first edition (ISO 13802:1999), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 13802:1999/Cor.1:2000.
This corrected version of ISO 13802:2015 incorporates the following correction:
— in Table 4, the pendulum length, L , in m, has been changed from “0,225 to 0,390” to “0,221 to 0,417”.

INTERNATIONAL STANDARD ISO 13802:2015(E)
Plastics — Verification of pendulum impact-testing
machines — Charpy, Izod and tensile impact-testing
1  Scope
This International Standard specifies frequency and 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. Verification of instrumented impact machines is
covered insofar as the geometrical and physical properties of instrumented machines are identical to
non instrumented machines. The force/work verification of instrumented machines is not covered in
this International Standard.
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.
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, has been repaired, has been moved, or
is undergoing periodic checking.
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 details design requirements for Charpy testing machines.
Annex B details design requirements for Izod testing machines.
Annex C details design requirements for tensile impact machines.
Annex D explains how to calculate the ratio of frame mass to pendulum mass required to avoid errors
in the impact energy.
Annex E explains deceleration of pendulum during impact.
Annex F details design requirements for one type of gauge used to verify striker and anvil/support
alignment for Charpy testing machine.
