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 (see 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 (see 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 of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 11357-7:2015), which has been
technically revised.
The main changes are as follows:
— an indication of suitable substances for checking the symmetry of the temperature scale has been
added;
— the procedure of determination of the start temperature of isothermal crystallization has been
corrected;
— an approach for the dependence of the rate constant of the Nakamura equation on temperature has
been added.
A list of all parts in the ISO 11357 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Plastics — Differential scanning calorimetry (DSC) —
Part 7:
Determination of crystallization kinetics
1 Scope
This document specifies two methods (isothermal and non-isothermal) for studying the crystallization
kinetics of partially crystalline polymers using differential scanning calorimetry (DSC).
It is only applicable to molten polymers.
NOTE These methods are not suitable if the molecular structure of the polymer is modified during the test.
