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 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-
chemical properties.
This second edition cancels and replaces the first edition (ISO 11359-1:1999), which has been technically
revised with the following changes:
— clarification that deformations shall occur under constant load;
— inclusion of reference to ISO 472 in Definitions and cancellation of duplicate and trivial definitions;
— revision of apparatus requirements following guidelines specified in ISO 11357-1 and update of
accuracy specifications;
— revision of specification of temperature calibration;
— revision of specification of displacement and sample length measurement.
ISO 11359 consists of the following parts, under the general title Plastics — Thermomechanical analysis
(TMA):
— Part 1: General principles
— Part 2: Determination of coefficient of linear thermal expansion and glass transition temperature
— Part 3: Determination of penetration temperature

INTERNATIONAL STANDARD ISO 11359-1:2014(E)
Plastics — Thermomechanical analysis (TMA) —
Part 1:
General principles
1 Scope
This part of ISO 11359 specifies the general conditions for the thermomechanical analysis of
thermoplastics and thermosetting materials, filled or unfilled, in the form of sheet or moulded parts.
Thermomechanical analysis consists of the determination of deformations of a test specimen under
constant load as a function of temperature and/or time.
