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 1183-1 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 1183-1:2004), which has been technically revised.
The main changes compared to the previous edition are as follows:
a) the equation used to calculate the dependence of the density of air on pressure and temperature in Clause 6
has been replaced by two equations, one for non-tropical conditions, the other for tropical conditions;
b) a new annex (Annex B) has been added showing how the basic air buoyancy correction equation
[Equation (5)] is derived.
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, liquid pyknometer method and titration method
— Part 2: Density gradient column method
— Part 3: Gas pyknometer method

INTERNATIONAL STANDARD ISO 1183-1:2012(E)
Plastics — Methods for determining the density of non-
cellular plastics —
Part 1:
Immersion method, liquid pyknometer method and titration
method
WARNING — The use of this part of ISO 1183 might involve hazardous materials, operations or equipment.
This part of ISO 1183 does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user of this part of ISO 1183 to establish appropriate health and
safety practices and to determine the applicability of any regulatory limitations prior to use.
1 Scope
This part of ISO 1183 specifies three methods for the determination of the density of non-cellular plastics in the
form of void-free moulded or extruded objects, as well as powders, flakes and granules.
— Method A: Immersion method, for solid plastics (except for powders) in void-free form.
— Method B: Liquid pyknometer method, for particles, powders, flakes, granules or small pieces of
finished parts.
— Method C: Titration method, for plastics in any void-free form.
NOTE This part of ISO 1183 is applicable to pellets as long as they are void-free. Density is frequently used to
follow variations in physical structure or composition of plastic materials. Density might also be useful in assessing the
uniformity of samples or specimens. Often, the density of plastic materials will depend upon the choice of specimen
preparation method. When this is the case, precise details of the specimen preparation method will have to be included in
the appropriate material specification. This note is applicable to all three methods.
2 Normative references
The following referenced documents are indispensable for the application 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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 472 and the following apply.
3.1
mass
m
quantity of matter contained in a body
NOTE It is expressed in kilograms (kg) or grams (g).

3.2
apparent mass
m
APP
mass of a body obtained by measuring its weight using an appropriately calibrated balance
NOTE It is expressed in kilograms (kg) or grams (g).
3.3
density
ρ
3 3 3
ratio of the mass m of a sample to its volume V (at the temperature t), expressed in kg/m , kg/dm (g/cm )
or kg/l (g/ml)
NOTE The following terms, based upon ISO 80000-4, are given in Table 1 for clarification.

4 Conditioning
The test atmosphere shall be in accordance with ISO 291. In general, conditioning specimens to constant temperature
is not required, because the determination itself brings the specimen to the constant temperature of the test.
Specimens which change in density during the test to such an extent that the change is greater than the required
accuracy shall be conditioned prior to measurement in accordance with the applicable material specification.
When changes in density with time or atmospheric conditions are the primary purpose of the measurements,
the specimens shall be conditioned as described in the material specification an
