Cellular plastics - Polyethylene - Methods of test (ISO/DIS 7214:2024)
ISO 7214:2012 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 as described in ISO 1872-1, or copolymers of ethylene as described in ISO 4613-1.
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 are described.

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 fourth edition cancels and replaces the third edition (ISO 7214:2007). Figure 1, which was dimensionally
incorrect in the previous edition, has been replaced by Figure 2 from ISO 34-1:2010.

Cellular plastics — Polyethylene — Methods of test
1 Scope
1.1 This International Standard 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 as described in ISO 17855-1, or copolymers of ethylene as
described in ISO 21301-1.
1.2 Mandatory tests suitable for characterization of cellular polyethylene, regardless of end use, are
described in Clause 7. Optional tests for the determination of properties that are relevant to certain uses are
described in Clause 8.
