Standard Test Method for Normal Impact of a Soft Projectile on a Hemispherical Leading Edge AS7371

This document describes a method for measuring deformations, and fragment distribution patterns during an impact between a soft or frangible projectile and a regular helispherical leading edge. The document describes the hardware, setup, and instrumentation required. In this test method a soft body projectile impacts a helispherical leading edge symmetric to the curvature and centric in the transversal direction. The ductile target is backup by a rigid adapter structure behind. The target must be sufficiently large so that the projectile flows around its curvature and induces an indentation. This test is intended for measuring the remaining plastic deformation of the target after the impact. The projectile breakup pattern data may also be captured during this test. The values stated in either SI units or inch-pound units are considered separate standards. The values stated in each system may not be exactly equivalent; therefore, each system must be considered as independent. This standard does not address all of the safety concerns associated with its use. It is the responsibility of each user of this standard to ensure that any safety issues are properly addressed.
