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 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/

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This first edition of ISO 24022-1 cancels and replaces ISO 1622-1:2012, which has been technically
revised to introduce a new designation system.
The main changes compared to the previous edition are as follows:
— in Clause 2, reference to ISO 1622-2 has been replaced by ISO 24022-2;
— Clause 3 has been added and subsequent clauses have been renumbered.
A list of all parts in the ISO 24022 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 24022-1:2020(E)
Plastics — Polystyrene (PS) moulding and extrusion
materials —
Part 1:
Designation system and basis for specifications
1 Scope
This document establishes a system of designation for polystyrene thermoplastic material, which can
be used as the basis for specifications.
The types of polystyrene plastics are differentiated from each other by a classification system based on
appropriate levels of the designatory properties:
a) Vicat softening temperature, and
b) melt mass-flow rate.
and on information about the intended application and/or method of processing, important properties,
additives and colorants, fillers and reinforcing materials.
This document is applicable to all amorphous polystyrene homopolymers. It applies to materials ready
for normal use, unmodified or modified by colorants, additives, fillers, etc.
This document does not apply to expanded polystyrene, styrene copolymers, homopolymers of
substituted styrene or those modified with other polymers such as elastomers.
It is not intended to imply that materials having the same designation give necessarily the same
performance. This document does not provide engineering data, performance data or data on
processing conditions which might be required to specify a material for a particular application and/or
method of processing.
If such additional properties are required, they are determined in accordance with the test methods
specified in ISO 24022-2, if suitable.
In order to specify a thermoplastic material for a particular application or to ensure reproducible
processing, additional requirements can be given in data block 5 (see 4.6).
