1.1本试验方法涵盖在一系列试验速度下测定硬质塑料的刺穿性能。 1.2通过本试验方法获得的试验数据相关且适用于工程设计。 1.3以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 笔记 1-本规范不完全符合ISO 6603.2。这两个试验之间唯一的相似之处在于，它们都是仪器化冲击试验。撞针、夹具和试样几何形状以及测试速度的差异可能会产生显著不同的测试结果。 ====意义和用途====== 本试验方法旨在提供冲击速度下基本多轴变形条件下塑料的载荷与变形响应。该试验方法进一步提供了材料对冲击的速率敏感性测量。 多轴冲击响应虽然部分取决于厚度，但不一定与试样厚度呈线性相关。因此，应仅对基本相同厚度的试样进行结果比较，除非已为材料建立了特定响应与厚度公式。 对于许多材料，可能有一个规范要求使用该试验方法，但在遵守规范时，一些程序修改优先。因此，建议在使用本试验方法之前参考该材料规范。 分类系统表1 D4000 列出了当前存在的ASTM材料标准。

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. No other units of measurement are included in this 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 D4000 lists the ASTM materials standards that currently exist.
