Standard Test Method for
Pendulum Impact Resistance of Plastic Film1
This standard is issued under the fixed designation D 3420; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers the determination of the resistance
of the film to impact-puncture penetration. Knowledge of how the
impact energy is absorbed by the specimen while it is deforming under the impact loading, and the behaviour of the specimen
after yielding, is not provided by this test. No provision is made
for nonambient temperatures in this test method.
1.2 The values stated in SI units are to be regarded as the
standard.
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. Specific hazards
statements are given in Section 7.
NOTE 1—There is no similar or equivalent ISO standard.
