Why Do We Test Body Armor With A Clay Box? #shorts
This video explains the critical role of clay boxes in testing body armor, focusing on back face deformation (BFD). As demonstrated by Predator Armor, BFD measures how much the armor indents inward after impact. Exceeding the 44mm limit signifies a failure point, as excessive deformation can lead to severe internal injuries. The video emphasizes that this test is universal across all body armor levels and involves multiple shots with varied ammunition.
