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. Esch 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
(1 EC) on all matters of electrotechnical standardization.
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 2818 was prepared by Technical Committee
lSO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
This third edition cancels and replaces the second edition
(ISO 2818:1980), which has been revised with respect to the following
Points:
- normative references for the geometry of cutting tools and abrasive
tools and products;
- introduction of notching;
- extension of the table for recommended machining conditions.

Introduction
The preparation of test specimens by machining influences the finished
surfaces and, in some cases, even the internal structure of the specimens.
Since test results are strongly dependent on both of these Parameters,
exact definitions of tools and machining conditions are required for repro-
ducible test results with machined specimens.
