preface
ISO (International Organization for Standardization) is the global federation of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the Committee. International, governmental and non-governmental organizations in liaison with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

International standards are drafted in accordance with the rules given in Part 2 of the ISO/IEC Directive.

The main task of the technical committee is to set international standards. The draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Publication as an international standard requires approval by a vote of at least 75% of the member body.

Please note that some elements of this document may be the subject of patent rights. ISO is not responsible for identifying any or all such patents.

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

This second edition cancels and replaces the first edition (ISO 23559:2007) by slightly revising the first edition (ISO 23559:2007) by introducing an additional specimen (for low strain) for the tensile impact test specified in Table 2.

ISO 23559-2011 Guide for testing plastic films and sheet thermoplastic Films

introduce
This international standard is intended to provide manufacturers and users with guidance for testing plastic film.

Although existing standards provide this guidance for many thin film products, they are very specific in terms of the materials covered and do not address many commercial films produced as mixtures or multilayer structures. In some cases, existing standards are limited to a single process technology for producing thin films.

It is also recognized that the general standardized concept of film sample preparation is not currently realistic due to the numerous commercial processes used to produce films and the different processing parameters required for different materials, mixtures and/or structures. On the other hand, it is possible to standardize sample preparation for clearly defined materials and manufacturing processes, but this is not within the scope or intent of this document.

Safety Statement – Persons using this document should be familiar with normal laboratory practices (if applicable). This document is not intended to address all security concerns, if any, associated with its use. It is the user’s responsibility to establish appropriate safety and health practices and ensure compliance with any regulatory requirements.

ISO 23559-2011 Guide for testing plastic films and sheet thermoplastic Films

1 Scope of application
This international standard identifies specific testing procedures to assist manufacturers and users in selecting and characterizing single – or multilayer thermoplastic films. It aims to provide a guide for films that do not have existing standards or specifications.

Note Due to the range of materials used and the variety of processes that can be used to produce various thin film structures, sample preparation is not covered in this document.

If an international standard exists for a particular film product, the requirements of that standard shall take precedence over this document.

There are many national, regional, and industry standards that address application-specific requirements. Since this international standard is intended to provide general guidance it is not within the scope of addressing these issues.

The importance and applicability of the data should be determined by the user.
