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

Introduction
The conditioning of test pieces prior to testing is commonly accepted as an essential practice in most, but not
necessarily all, methods of test. Its purpose is to provide a common ground base for the commencement of the
test and to remove an unnecessary variable in the search for th
