ISO 7214:2007 PDF

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.
