The work of preparing International Standards is normally c
8、arried 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 wor
9、k. 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 Interna
10、tional 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 e
11、lements 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.This second edition cancels and replaces the first edition (IS
12、O 23559:2007), of which it constitutes a minor revision to introduce an additional test specimen (for low strains) for the tensile impact test specified in Table 2.ISO 23559:2011(E) ISO 2011 All rights reserved iiiBS ISO 23559:2011IntroductionThis International Standard has been prepared to provide
13、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 mul
14、ti-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, ble
15、nds 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 doc

This
17、 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 ScopeThis International Standard identifies specifi
18、c 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
19、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, regi
20、onal 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.2 Normative r

The number of specimens shall be determined by the requirements of the specific test standard.It is not necessary that all of the tests in Table 2 be conducted in every case. The specific tests will depend, in part, on the type of
