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 23559 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

Introduction
This International Standard has been prepared to provide guidance in the testing of plastic films for producers
and users.
Although there are existing standards that provide this guidance for a number of film products, these are quite
specific in respect to the materials covered and do not address many commercial films that are produced as
blends or as multi-layer structures. In some cases, the existing standards are limited to only one process
technique for producing the film.
It is also recognized that, because of the multitude of commercial processes used to produce films and the
different processing parameters required for different materials, blends and/or structures, the concept of
general standardization of film specimen preparation is not realistic at this time. On the other hand, it is
possible to standardize specimen preparation for well-defined materials and fabrication processes but this is
not within the scope or intent of this document.

INTERNATIONAL STANDARD ISO 23559:2007(E)

Plastics — Film and sheeting — Guidance on the testing
of thermoplastic films
SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory
practice, if applicable. This document does not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any regulatory requirements.
1 Scope
This International Standard identifies specific test procedures to assist producers and users in the selection
and characterization of thermoplastic films in single- or multi-layer form. It is intended to serve as a guide for
those films for which there are no existing standards or specifications.
NOTE Because of the range of materials used and the wide variety of processes available to produce various film
constructions, this document does not address specimen preparation.
If an International Standard exists for a specific film product, the requirements of that standard shall take
precedence over this document.
There are many national, regional and industrial standards that address the requirements for specific
applications. Since this International Standard is intended to provide general guidance, it is not within the
scope to address these.
The significance of the data and fitness for use shall be determined by the user.
