Cellular plastics - Polyethylene - Methods of test (ISO 7214:2007)
ISO 7214:2007 specifies methods for testing flexible and semi-rigid cellular plastics made from polyethylene. Cellular plastics containing copolymers of ethylene or blends of polymers with polyethylene may also be tested by the procedures of this International Standard provided these materials have characteristics similar to polyethylene or copolymers of ethylene.
The tests are divided into mandatory tests suitable for characterization of cellular polyethylene regardless of end use, and optional tests for the determination of properties that are relevant to certain uses only.
Schaumstoffe - Polyethylen - Prüfverfahren (ISO 7214:2007)
1.1 Diese Internationale Norm legt Prüfverfahren für weich-elastische und halbharte Schaumstoffe aus Polyethylen fest. Schaumstoffe, die Ethylen-Copolymere oder Mischungen aus Polymeren mit Polyethylen enthalten, dürfen ebenso nach den Verfahren dieser Internationalen Norm geprüft werden, vorausgesetzt, diese Materialien haben ähnliche Eigenschaften wie Polyethylen nach ISO 1872 1 oder Ethylen-Copolymere nach ISO 4613 1.
1.2 Im Abschnitt 7 sind obligatorische Prüfverfahren festgelegt, die für die Kennzeichnung der Polyethylen¬schaumstoffe geeignet sind, ohne die Anwendung zu berücksichtigen. Im Abschnitt 8 werden die wahlfreien Prüfverfahren zur Bestimmung von Eigenschaften, die sich auf bestimmte Einsatzgebiete beziehen, beschrie¬ben.
Plastiques alvéolaires - Polyéthylène - Méthodes d'essai (ISO 7214:2007)
L'ISO 7214:2007 spécifie des méthodes d'essai applicables aux matériaux plastiques alvéolaires souples et semi-rigides, fabriquées en polyéthylène. Les matériaux plastiques alvéolaires contenant des copolymères de l'éthylène ou des mélanges de polymères et de polyéthylène peuvent également être soumis à l'essai conformément aux modes opératoires spécifiés dans l'ISO 7214:2007, à condition qu'elles possèdent des caractéristiques similaires à celles du polyéthylène ou à celles des copolymères de l'éthylène.
Deux catégories d'essais sont spécifiées: les essais de base, qui permettent de caractériser les polyéthylènes alvéolaires indépendamment de leur destination finale, et les essais supplémentaires, qui permettent de déterminer les propriétés qui sont utiles dans le cas de certaines utilisations.

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 7214 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10, Cellular plastics.
This third edition cancels and replaces the second edition (ISO 7214:1998), which has been technically
revised.

3 Test specimens
The specimens shall be cut so that the edges are clean and the sides are planar and normal to the surface.
The specimens shall be cut from the sample so that a representative value is determined for each physical
property investigated. With anisotropic samples, take specimens in the appropriate direction.
Clauses 7 and 8 outline the requirements for the number of specimens, their shape and their dimensions.
Unless otherwise required by a specific test method, the surfaces of the specimens shall be the same as the
surface of the material in normal use.
4 Conditioning
Unless otherwise specified in Clause 7 or 8, specimens shall be conditioned for a minimum of 24 h at
(23 ± 2) °C and (50 ± 10) % relative humidity
