Scope

1.1 This test method covers the determination of puncture properties of rigid plastics over a range of test velocities.

1.2 Test data obtained by this test method are 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 specification does not closely conform to ISO 6603.2. The only similarity between the two tests is that they are both instrumented impact tests. The differences in striker, fixture, and specimen geometries and in test velocity can produce significantly different test results.

Significance and Use

This test method is designed to provide load versus deformation response of plastics under essentially multiaxial deformation conditions at impact velocities. This test method further provides a measure of the rate sensitivity of the material to impact.

Multiaxial 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 material.

For many materials, 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 method. Table 1 of Classification System D 4000 lists the ASTM materials standards that currently exist.
