NATO AEP-55 STANAG 4569 is a NATO Standardization Agreement covering the standards for the "Protection Levels for Occupants of Logistic and Light Armored Vehicles".[1]
The standard covers strikes from kinetic energy, artillery and IED blasts.
7.62×51mm NATO Ball (Ball M80) at 30 meters with velocity 833 m/s[1][2]
5.56×45mm NATO Ball (SS109) at 30 meters with a velocity of 900 m/s
5.56×45mm NATO Ball (M193) at 30 meters with a velocity of 937 m/s
Protection against all three threats must be provided.
Hand grenades, unexploded artillery fragmenting submunitions, and other small anti personnel explosive devices detonated under the vehicle.
20 mm FSP (simulating 155 mm threat) at 520 m/sec from a distance of 100 meters. (Due to very low probability of a large fragment retaining enough velocity at these distances, STANAG 4569 makes this optional.)[3]
