Plastics - Differential scanning calorimetry (DSC) - Part 1: General principles (ISO 11357-1:2009)
ISO 11357 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as
thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements);
thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements);
elastomers (with or without fillers, fibres or reinforcements).
ISO 11357 is intended for the observation and measurement of various properties of the above-mentioned materials, such as

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 11357-1 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 11357-1:1997), which has been technically
revised. The most important changes are the following:
⎯ an indication has been given of the preferred graphical representation of DSC diagrams in accordance
with thermodynamic requirements;
⎯ an additional, more precise, method of temperature calibration, providing an accuracy of ± 0,3 K over an
extended temperature range, has been included;
⎯ an additional, more precise, procedure for enthalpy calibration, providing an accuracy of ± 0,5 %, has
been included;
⎯ a procedure for heat flow rate calibration has been included;
⎯ information has been included on interactions between calibration materials and the crucibles.
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
