PERIMETER INTEGRITY: SECURE

PAS 68 K12 barrier absorbed 347.2 kJ. Hostile vehicle halted within 0.60m. Pedestrian refuge zone remains completely safe.

Standard Penetration Thresholds (ASTM F2656)

Class	Max Penetration	Safety Zone Margin
P1	≤ 1.0 m	Optimal (Refuge Safe)
P2	1.01 m - 7.0 m	Marginal (Shallow buffer breached)
P3	7.01 m - 30.0 m	Critical Failure / Fatal Breach

Engineering Notes

HVM measures are specified to prevent vehicle ramming threats in dense pedestrian spaces. Kinetic energy scales quadratically with approach speed: doubling velocity quadruples structural dissipation requirements.
