Organization: ASTM International
Publication Date: 1 February 2004
Status: inactive
Page Count: 8
ICS Code (Films and sheets): 83.140.10
scope:

1.1 This test method covers the determination of the relative ranking of materials according to the energy required to crack or break flat, rigid plastic specimens under various specified conditions of impact of a striker impacted by a falling weight.

1.2 The values stated in SI units are to be regarded as the standard. The values given in brackets 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 1-There is no similar or equivalent ISO standard.
