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 11357-2 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 11357-2:1999), which has been technically
revised. Significant technical changes are the following:
— deletion of duplicate text contained in ISO 11357-1;
— inclusion of determination of step height;
— description of characteristic glass temperatures moved from 3.3 to 10.1;
— inclusion of additional methods of determination of T based on inflection point and equal-areas
g
calculation.
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
