Description
This air and helium powered device allows for the assessment of the ballistic protective properties of developmental and commercial eyewear. It is capable of shooting either 5.8 grain or 17 grain fragment simulating projectiles at up to 950 ft/s, or the .25 inch round ball used for the ANSI Z87.1 safety eyewear test. It can also assess flat or curved samples, or the complete eyewear "as worn" on a headform, and at ambient or at extreme temperatures (-60° F to +160° F).
