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
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties.
This fourth edition cancels and replaces the third edition (ISO 1183-1:2019), which has been technically
revised. The main changes compared to the previous edition are as follows:
— In Clause 4, the temperature specifications of the immersion liquid and air have been added.
— In Clause 5.1, an alternate version of the immersion method has been introduced which does not
need a wire to suspend the specimen.
— In 5.1, the technical requirements for the pycnometer, the thermometer and the immersion liquids
have been revised.
— In 5.1, the (classic) procedure using a wire to suspend the specimen has been clarified.
— In 5.1.4, the Formulae for the calculation of the density have been revised to include the buoyancy in
air.
— Clause 6 has been deleted, the buoyancy correction has been moved to 5.1.4.4 and the calculation of
the density of air has been moved to Annex B.
— Annex B (changed from informative to normative) has been shortened to cover the calculation of
air only. The method of correction for buoyancy of air has been revised and is now included in
formulae (3) and (4) in 5.1.4.4.
— Annex C (informative) has been added to present formulae for the determination of the volume of
specimens measured by the immersion method.
— Annex D (informative) has been added to explain the updated formulae in 5.1 and Annex C.
