Review of Ballistic standards
NIJ = United States National Institute of
Justice standard www.justnet.org
International / Local standards
Levels IIA, II and IIIA protect against hand
guns
Levels III and IV protection against rifles
NIJ Standard 0101.04
NIJ LEVEL
BULLET TYPES
IIA
9mm FMJ, .40 S & W
II
9mm FMJ, .357 Mag JSP
IIIA
9mm FMJ, .44 Mag SJHP
III
7.62 x 51 NATO FMJ
IV
.30 M2 AP

MIL STD and STANAG
NIJ = V0 standard, stop pass/no stop fail
Ballistic resistance of body armor NIJ std
0101.06
http://www.ncjrs.gov/pdffiles1/nij/223054.pdf
Mil Std 662E (USA) and STANAG 2920
(NATO) are V50 standards using a FSP
(fragment simulation projectile) (17gr FSP)
Stab resistance armor
US STD NIJ 0115.00

Anti stab and anti spike are different
Solutions can be woven, chainmail,
platelets, steel, aluminium, titanium wire

Firstly to meet the specified standard
To construct the best functional carrier
The produce the lightest, most flexible and most
comfortable solution
To provide a cost effective package
Selecting body armor
Chose the correct Level of protection
Select only independently certified armor
Balance weight and flexibility versus price
Allow the manufacturer to use their skills
Consider breathability and comfort
Chose a reputable manufacturer
Measurement of Performance
The V50 is usually used as the basic measurement
of performance
V50 is the 50% probability of penetration of
defined bullet type expressed in terms of velocity
in m/sec (or in the USA fps)
Areal weight is also used and this is expressed in
terms of kg/m2 (or in the USA lbs/ft2)
Sometimes these two references are used to
express a RPI (Relative Performance Indicator)
V50 divided by A/D – This enables comparative
evaluation between armor types
Blunt Trauma
The US National Institute of Justice Standard
is 44 mm maximum depth of indentation on
the body side, or trauma, measured on a
clay similar to Roma Plastilina #1
Body armor solution= protection x comfort
International Standards BFS
