1.1本试验方法 描述了在0至10 000 psig（0至68.9 MPa）的压力下，测定材料对液氧或气氧中机械冲击的相对灵敏度的试验装置和技术。本文所述的试验方法涉及纯氧环境下的试验；然而，富氧液体可在本文件中替代。本试验方法使用陆军弹道导弹局（ABMA）型冲击试验机，其类型如试验方法D2512中所述，为加压试验而修改。 1.2本试验方法提供了一种对指南G63中定义的用于液态和气态氧系统的非金属材料进行排序的方法，不直接适用于确定最终用途配置中材料的灵敏度。本试验方法可用于提供批次- 批量验收数据。 1.3材料验收、重新试验或拒收所用的标准应由用户确定，且不受本试验方法的固定。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。另见第7节。

1.1 This test method describes test apparatus and a technique to determine the relative sensitivity of materials to mechanical impact in liquid or gaseous oxygen at pressures from 0 to 10 000 psig (0 to 68.9 MPa). The test method described herein addresses testing with pure oxygen environments; however, oxygen-enriched fluids may be substituted throughout this document. This test method utilizes an Army Ballistic Missile Agency (ABMA)-type impact tester of the type depicted in Test Method D2512 modified for pressurized testing. 1.2 This test method provides a means for ranking nonmetallic materials as defined in Guide G63 for use in liquid and gaseous oxygen systems, and is not directly applicable to the determination of the sensitivity of the material in an end-use configuration. This test method can be employed to provide batch-to-batch acceptance data. 1.3 The criteria used for the acceptance, retest or rejection of materials shall be determined by the user and are not fixed by this test method. 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. See also Section 7.
