Active Standard ASTM D2305 | Developed by Subcommittee: D09.07
Book of Standards Volume: 10.01
Historical (view previous versions of standard)
Significance and Use
Many electrical and physical properties of films vary significantly with changes in temperature and humidity. Properties of thin plastic films can change very rapidly; therefore, the specimen needs to be in the stated conditioning environment when the test is being performed. When the test is performed in a different environment, note these conditions and the time of exposure to this new environment.
1.1 These test methods cover the testing of homogeneous organic polymer films not over 2.4 mm (95 mils) thick that are to be used for electrical insulation.
1.2 These test methods are not necessarily applicable to testing films in combinations with a coating, another film, or with other types of substrate, such as fabrics or papers.
1.3 The values stated in SI units are the standard. The values in parentheses are provided for information only.
