Armor Levels
A Comprehensive Table of Current Ballistic Standards for Body Armor and Helmets:
Like the glossary, this page “Armor Levels” is wholly derived from our book Body Armor Materials and Systems, where it is included in that book as an appendix. The aim here is to clearly lay out the different test protocols for armor that are in use globally, so that comparisons can be run and insights can be gleaned. Moreover, as Adept Armor does a lot of work with the European VPAM test protocols, we believe it is vital that those protocols be made widely available and comprehensible. Every effort will be made to ensure that the information on this page stays current. If you have any questions or comments, please contact us.

Notes:
– Three shots are placed on each armor panel during testing, regardless of threat level.
– Backface deformation is measured, and up to roughly 50mm is allowed in body armor applications. When VPAM is adapted for helmet testing, the limits are much more strict, corresponding very roughly to 10-12mm.

– Three shots per plate are placed on hard armor plates tested to HO3 and HO4.
– One shot is placed on hard armor plates tested to SG1.
– There is an optional “special threat” protocol which includes M855 and .357 Magnum, but the use of this protocol is optional, and these threats are not assigned a level. Oddly, under this special threat protocol, the BFD limit for M855 is 30mm, rather than the 44mm that is listed for all other threats.

Three shots of 9.5 g (147 gr) 7.62×54mmR LPS mild steel core FMJ bullets at a velocity of 840 m/s ± 15.3 m/s (2750 ± 50 ft/s).

| FBI Soft Armor |
8 g (124 gr) 9 mm FMJ RN bullets at a velocity of 431 m/s ± 13.7 m/s (1415 ft/s ± 45 ft/s) — Designated “control” or “test” projectile 8.2 g (127 gr) SXT +P+. Unspecified velocity. Specified: 8.85” barrel with 1:9.84” rate of twist. Contact shots. Service weapons: Multiple shots, including contact shots, from calibers and at velocities not specified. |
– The FBI test is an unusually involved and detailed process. It calls for four armor panels.
– The first is impacted with the 9mm FMJ control projectile six times, and then shot twice with the same projectile within 1.5” to 2” of the ballistic panel’s edge.
– The second panel is conditioned at 140°F for 14-24 hours, and then shot three times with the control projectile.
– The third panel is conditioned at -40°F for 14-24 hours, and then shot three times with the control projectile.
– The fourth panel is submerged approximately 18”- 24” in room temperature tap water for 14-24 hours, and is then pulled from the water and immediately shot three times with the control projectile.
– At random, the second, third, or fourth panel is then taken and shot with the control projectile at point-blank, contact-shot range.
– The second or fourth panel is then taken and shot under normal conditions with the current general-issue FBI sidearm and projectile. (Unspecified.)
– The third panel is then taken and subjected to a point-blank contact shot from the 9mm SXT 127 grain +P+ projectile, using a 8.85” barrel with a 1:9.84” rate of twist. (Velocity neither specified nor recorded.)

– The DEA soft armor test protocol is much like the FBI protocol, and unlike NIJ .06 or .07, in that it involves extensive conditioning and contact-shot test requirements. The two protocols are almost identical in this respect. But the DEA soft armor protocol is unlike the FBI protocol in that it also tests against fragment-simulating projectiles, which are made of solid steel and are known to give soft armor panels some trouble.
– The DEA hard armor protocol does not require such conditioning, nor does it require contact shots, and BFD is not measured or limited. In many respects, it’s the easiest protocol for a hard armor plate to pass.
US Military – Helmet
| Armor Level | Protection |
| PASGT | Fragmentation testing: .22 caliber, 17 gr. FSP. Minimum V50: 610 m/s (2000 ft/s) |
| ACH, ACH Gen II |
8 g (124 gr) 9 mm FMJ RN at a velocity of 426.7 m/s + 15.3 m/s (1400 ft/s + 50 ft/s) Fragmentation testing — 2 grain right circular cylinder. Minimum V50: 1280 m/s (4200 ft/s) 4 grain RCC. Minimum V50: 1059 m/s (3475 ft/s) 16 grain RCC. Minimum V50: 754 m/s (2475 ft/s) 64 grain RCC. Minimum V50: 533.5 m/s (1750 ft/s) .22 caliber, 17 grain FSP. Minimum V50: 670.5 m/s (2200 ft/s) |
| ECH |
8 g (124 gr) 9 mm FMJ RN at a velocity of 426.7 m/s + 15.3 m/s (1400 ft/s + 50 ft/s) Fragmentation testing — 2 grain right circular cylinder. Minimum V50: 1728 m/s (5670 ft/s) 4 grain RCC. Minimum V50: 1432 m/s (4700 ft/s) 16 grain RCC. Minimum V50: 1018 m/s (3340 ft/s) 64 grain RCC. Minimum V50: 719 m/s (2360 ft/s) .22 caliber, 17 grain FSP. Minimum V50: 905 m/s (2970 ft/s) Additional: Classified “small arms threat” — presumed to be, based on the commercial availability of ECH-type helmets, 7.62x51mm NATO ball at a 200-300 meter standoff. |
| IHPS |
8 g (124 gr) 9 mm FMJ RN at a velocity of 426.7 m/s + 15.3 m/s (1400 ft/s + 50 ft/s) Fragmentation testing — 2 grain right circular cylinder. Minimum V50: 1728 m/s (5670 ft/s) 4 grain RCC. Minimum V50: 1432 m/s (4700 ft/s) 16 grain RCC. Minimum V50: 1018 m/s (3340 ft/s) 64 grain RCC. Minimum V50: 719 m/s (2360 ft/s) .22 caliber, 17 grain FSP. Minimum V50: 905 m/s (2970 ft/s) Additional: Two classified small arms threats. One at a minimum 1300 fps V50, the other at a classified velocity, though presumably quite similar to the ECH. |
– When tested against the 9mm handgun round, ACH and ACH Gen II requirements call for less than 25.4mm BFD at the front and back, and less than 16mm at the crown and sides.
– There is no BFD limit for the ECH and IHPS against the classified small arms threats. BFD requirements against the 9mm handgun round are identical to those in the ACH specification.
US FBI/DEA Helmet Protocol
| Armor Level | Protection |
| FBI/DEA Helmet | 8 g (124 gr) 9 mm FMJ RN at a velocity of 426.7 m/s + 15.3 m/s (1400 ft/s + 50 ft/s) |
– Testing is modeled after VPAM helmet testing specifications, and imposes extremely strict limits on behind-helmet blunt impact trauma.
