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 3.
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.
International Standard ISO 1183-3 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5,
Physical-chemical properties. Together with the other parts (see below), it cancels and replaces ISO 1183:1987,
which has been technically revised.
ISO 1183 consists of the following parts under the general title, Plastics — Methods for determining the density of
non-cellular plastics:
 Part 1: Immersion method, pyknometer method and titration method
 Part 2: Density gradient column method
 Part 3: Gas pyknometer method

Introduction
This part of ISO 1183 is one of a series dealing with methods of measuring the density of solid non-cellular plastics.
The values obtained using this part of ISO 1183 are expected to be comparable to those obtained using the other
parts.
Density measurements may be used to investigate variations in the physical structure or the molecular order of
materials. Such measurements are widely used to determine the degree of crystallinity of polymers. In addition, they
may be used to determine the amount of filler present.
The density of a plastic material may depend on any conditioning or thermal treatment which the material has
undergone.
The physical structure of a polymer can change with time and temperature. Its volume is also a temperature-
dependent property. This means that the density may vary with time and/or temperature.

1 Scope
This part of ISO 1183 specifies a method for the determination of the density or the specific volume of solid non-
cellular plastics of any shape which do not contain closed pores.
2 Terms, definitions, symbols, units and abbreviated terms
For the purposes of this part of ISO 1183, the following terms, definitions, symbols, units and abbreviated terms
apply:
2.1
test material
material to be tested
2.2
test specimen
that part of the test material actually subjected to the test
2.3
mass
m
quantity of matter contained in a body
NOTE Mass is expressed in kilograms (kg) or grams (g).

NOTE 3 Density is to be distinguished from specific gravity, which is the ratio of the weight of a given volume of a material to
that of an equal volume of water at a stated temperature T.
3 Principle
3.1  The volume of a specimen of known apparent mass is determined by measuring the change of gas volume
within a pyknometer upon introducing the specimen. The volume change may be obtained either directly by means
of a movable piston or indirectly by measuring the change of the pressure within the pyknometer and calculating the
volume using the pressure-
