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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
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

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical
chemical properties.
This fourth edition cancels and replaces the second edition (ISO 11357-3:2018), which has been
technically revised.
The main changes are as follows:
— the scope has been limited to conventional DSC excluding fast DSC.

Plastics — Differential scanning calorimetry (DSC) —
Part 3:
Determination of temperature and enthalpy of melting and
crystallization
1 Scope
This document specifies a method for the determination of the temperatures and enthalpies of melting
and crystallization of crystalline or partially crystalline plastics using conventional DSC as specified in
ISO 11357-1.
This document is not applicable to fast DSC as specified in ISO 23976.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 472, Plastics — Vocabulary
ISO 11357-1, Plastics — Differential scanning calorimetry (DSC) — Part 1: General principles
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 472, ISO 11357-1 and the
following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
melting
transition stage between a fully crystalline or partially crystalline solid state and an amorphous liquid
of variable viscosity
Note 1 to entry: The transition, also referred to as “fusion”, is characterized by an endothermic peak in the DSC
curve. An exception to this definition is the case of liquid crystals, where the term “amorphous liquid” is replaced
by “ordered liquid”.
3.2
crystallization
transition stage between an amorphous liquid state and a fully crystalline or partially crystalline solid
state
Note 1 to entry: The transition is characterized by an exothermic peak in the DSC curve. An exception to this
definition is the case of liquid crystals, where the term “amorphous liquid” is replaced by “ordered liquid”.
ISO/DIS 11357-3:2023(E)
3.3
enthalpy of fusion
heat required to melt a material at constant pressure
Note 1 to entry: It is expressed in kilojoules per kilogram (kJ/kg) or joules per gram (J/g).
3.4
enthalpy of crystallization
heat released by the crystallization of a material at constant pressure
Note 1 to entry: It is expressed in kilojoules per kilogram (kJ/kg) or joules per gram (J/g).
