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 472 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 1, Terminology.
This fourth edition cancels and replaces the third edition (ISO 472:1999), which has been technically revised.

INTERNATIONAL STANDARD ISO 472:2013(E/F)
Plastics — Vocabulary
1 Scope
This International Standard defines terms used in the plastics industry, including terms and definitions
appearing in plastics standards (of ISO/TC 61) and general terms and definitions of polymer science
used in all aspects of plastics technology.
NOTE In addition to terms in English and French (two of the three official ISO languages), this vocabulary
includes the equivalent terms in German; these have been included under the responsibility of the member body
for Germany (DIN). However, only the terms and definitions in the official languages can be considered as ISO
terms and definitions.
2 Terms and definitions
When a term has one or more synonyms, they follow the preferred term. The synonyms are listed in
alphabetical order. Deprecated terms are indicated by “(deprecated)”.
IUPAC rules for source-based names of polymers specify that, when “poly” is followed by more than one
word, parentheses are used. The IUPAC practice is followed in this International Standard. In common
use, the parentheses are often omitted.
For terms involving olefins, the name used commonly in the plastics industry has been utilized rather
than the (scientific) name approved by IUPAC; for example, polyethylene is used as opposed to polyethene.
Some definitions in this International Standard begin with information in angled brackets. This has
been added to indicate limitation of the definition to a particular field.
In the English text, the word class (i.e. “noun”, “verb” or “adjective”) of terms is indicated where necessary
to avoid ambiguity.
