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 148-3 was prepared by Technical Committee ISO/TC 164, Mechanical testing of metals, Subcommittee
SC 4, Toughness testing — Fracture (F), Pendulum (P), Tear (T).
This second edition cancels and replaces the first edition (ISO 148-3:1998) which has been technically revised.
ISO 148 consists of the following parts, under the general title Metallic materials — Charpy pendulum impact
test:
⎯ Part 1: Test method
⎯ Part 2: Verification of testing machines
⎯ Part 3: Preparation and characterization of Charpy V-notch test pieces for indirect verification of
pendulum impact machines

Introduction
The suitability of a pendulum impact testing machine for acceptance testing of metallic materials has usually
been based on a calibration of its scale and verification of compliance with specified dimensions, such as the
shape and spacing of the anvils supporting the specimen. The scale calibration is commonly verified by
measuring the mass of the pendulum and its elevation at various scale readings. This procedure for
evaluation of machines had the distinct advantage of requiring only measurements of quantities that could be
traced to national standards. The objective nature of these traceable measurements minimized the necessity
for arbitration regarding the suitability of the machines for material acceptance tests.
However, sometimes two machines that had been evaluated by the direct-verification procedures described
above, and which met all dimensional requirements, were found to give significantly different impact values
when testing test pieces of the same material. This difference was commercially important when values
obtained using one machine met the material specification, while the values obtained using the other machine
did not. To avoid such disagreements, some purchasers of materials added the requirement that all pendulum
impact testing machines used for acceptance testing of material sold to them must be indirectly verified by
testing reference test pieces supplied by them. A machine was considered acceptable only if the values
obtained using the ma
