Standard Test Method for Determining Ignition Sensitivity of Materials to Mechanical Impact in Ambient Liquid Oxygen and Pressurized Liquid and Gaseous Oxygen Environments

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.
