ASTM D7192-08

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Test Method for
High Speed Puncture Properties of Plastic Films Using Load

and Displacement Sensors
This standard is issued under the fixed designation D 7192; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This test method covers the determination of puncture properties of plastic films, over a range of test velocities.
1.1.1 Test Method D 1004 has defined film as having a thickness not greater than 0.25 mm (0.010 in.). Plastic materials having
a thickness above this limit are not to be excluded from use unless shown to be rigid (see 3.2.1). Test Method D 3763 is the
recommended method for instrumented puncture testing of rigid plastics.
1.2 Test data obtained by this test method is relevant and appropriate for use in engineering design.
1.3 The values stated in SI units are to be regarded as standard.
1.4 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—This test method does not closely conform to ISO 7765-2.The only similarity between the two tests is that they are both instrumented impact
tests. The differences in striker, fixture, specimen geometries and in test velocity can produce significantly different test results.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 rigid, adj—anyplasticspecimenthat,whenplacedonthesupportcomponentoftheopenclampassembly,doesnotdeflect
into the center of the unsupported region (under its own weight) by more than 0.05 mm from the horizontal plane of the support
component.
3.2.1.1 Discussion—This definition is provided as a guideline to allow testing of soft, pliable plastic materials that are thicker
than 0.25 mm.
4. Significance and Use
4.1 This test method is designed to provide load versus deformation response of plastic films under essentially multi-axial
deformation conditions at impact velocities. This test method further provides a measure of the rate sensitivity of the plastic films
to impact.
4.2 Multi-axial impact response, while partly dependent on thickness, does not necessarily have a linear correlation with
specimen thickness. Therefore, results should be compared only for specimens of essentially the same thickness, unless specific
responses versus thickness formulae have been established for the plastic films being tested.

4.3 For many plastic films, there may be a specification that requires the use of this test method, but with some procedural
modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material
specification before using this test meth
