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 in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received. www.iso.org/patents
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 5, Physical and
chemical properties.
This second edition cancels and replaces the first edition (ISO 11357-4:2005). This minor revision
contains the following changes:
a) all normative reference were changed into undated ones;
b) the term “pan” was replaced by “crucible” within the whole text;
c) the endothermic direction, a, was added in all figures and key.
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 and glass transition step height
— 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
