Every straight and curve.
Friction- and powertrain-limited, with EV instant torque included. A three-pass solve applies curvature limits in every bend and a braking envelope back from each downstream constraint.

Model the real approach. Solve the critical impact speed. Right-size the barrier, in minutes.
VECTOR solves the critical impact speed along the entire approach path, every straight and curve, friction- and powertrain-limited with EV instant torque included. It then evaluates that one impact in parallel under ASTM F2656, ASTM F3016 and ISO 22343-1, returns the effective rating under each, and documents all of it beside the legacy check in a report.
Screening estimate
29.7 mph at impact. The vehicle starts from a stop and the short run-up caps the speed. M30 is the effective rating for the 15,000-lb design vehicle. The legacy check assumed 42.4 mph and demanded an M50.

One impact. Three standards, evaluated in parallel
VECTOR evaluates every approach under ASTM F2656, ASTM F3016 and ISO 22343-1 at the same time and reports what each standard requires for the same impact. You select the governing framework for the project; the other two stay on screen as alternatives, and the withdrawn legacy editions are listed for interpreting existing installations only. Determinations are parallel, not equivalent: each is derived from the same impact vector under that standard's own test vehicles, speed tiers and penetration classes.

Governing framework: U.S. Federal / DoD / DoS. Legacy equivalents, withdrawn: IWA 14-1 V/7200[N2A]/48/90 · PAS 68 V/7500[N2]/48/90. DoS K-rating cross-reference: K4 (informational only).
Governing framework by project

Two readings under each standard
Energy-equivalence and class-anchored. Where they differ, the more onerous governs and the report says why.
Penetration class from your setback
Under each standard's own datum.
Product-rating check
Paste a certificate rating such as F2656-23 M50-P1 or V/7500[N3]/80/90:2.2 and VECTOR states whether it envelopes the threat, with the reasons.

What VECTOR does
Both readings, side by side.
VECTOR beside the legacy single-radius check, and three standards evaluated in parallel, with the effective rating under each and the penetration class from your setback.
A report in minutes.
Every input recorded and the screening basis stated, or an engineer-reviewed and signed issue.
One standards registry.
Withdrawn editions are flagged and never shown as current.
What VECTOR computes
01
Critical velocity profile
A three-pass solve over the whole approach: curvature limits in every bend, traction- and power-limited acceleration on the straights, and a braking envelope back from each downstream constraint — coupled through the friction circle.
02
Effective rating
The perpendicular kinetic energy at the barrier line sets the effective rating under ASTM F2656, an ASTM F3016 S-rating where the vector falls inside the low-speed envelope, and the ISO 22343-1 vehicle class and speed tier, each with the required penetration class from your setback. Two readings are taken under each standard, energy-equivalence and class-anchored, and the more onerous governs.
03
Documented report
A complete input register, method comparison against the legacy single-radius check, both figures, and the full limitations and disclaimer package — or an engineer-reviewed and signed issue.
