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 11357-6 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties.
This second edition cancels and replaces the first edition (ISO 11357-6:2002), which has been technically
revised. The most important changes in the revision are the following:
⎯ a dynamic OIT method, i.e. the measurement of oxidation induction temperature, has been included;
⎯ it is now possible to perform measurements in air as well as in oxygen;
⎯ the range of specimen sizes has been narrowed and specimen size has been redefined in terms of
thickness instead of mass;
⎯ the possibility of making single-point routine measurements with reduced accuracy has been included.
It also cancels and replaces ISO/TR 10837:1991.
ISO 11357 consists of the following parts, under the general title Plastics — Differential scanning calorimetry
(DSC):
⎯ Part 1: General principles
⎯ Part 2: Determination of glass transition temperature
⎯ Part 3: Determination of temperature and enthalpy of melting and crystallization
⎯ Part 4: Determination of specific heat capacity
⎯ Part 5: Determination of characteristic reaction-curve temperatures and times, enthalpy of reaction and
degree of conversion
⎯ Part 6: Determination of oxidation induction time (isothermal OIT) and oxidation induction temperature
(dynamic OIT)
⎯ Part 7: Determination of crystallization kinetics
In this corrected version, the sixth paragraph in the Foreword has been modified to reflect the fact that the
second edition replaces not only the first edition but also ISO/TR 10837:1991, Determination of the thermal
stability of polyethylene (PE) for use in gas pipes and fittings.

Introduction
It should be noted that the measurement of oxidation induction time or temperature described in this part of
ISO 11357 provides a tool to assess the conformity of the material tested to a given formulation of plastics
compounds, but it is not intended to provide the concentration of antioxidant. Different antioxidants may have
different oxidation induction times or temperatures. Due to interaction of the antioxidant with other substances
in the formulation, different oxidation induction times or temperatures may result even with products having
the same type and concentration of antioxidant.
