ASTM D4272-08
Historical Standard: ASTM D4272-08 Standard Test Method for Total Energy Impact of Plastic Films By Dart Drop
SUPERSEDED (see Active link, below)
ASTM D4272
1. Scope
1.1 This test method describes the determination of the total energy impact of plastic films by measuring the kinetic energy lost by a free-falling dart that passes through the film.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1This test method and ISO 7765 2 address the same subject matter, but differ in technical content (and results cannot be directly compared between the two test methods). The ISO test method calls for a direct readout of energy by using a load cell as part of the impactor head, while Test Method D 4272 calls for a constant weight impactor, then measuring the time of travel through a given distance to get energy values.
