Most of us wonder the
difference between type 3 and type 3a body armor. What does the ‘a’ + (example,
3a) after the threat type mean? Together, let us take a look at this post and
learn the difference between a type 3 and type 3a body armor.
During the 1970s, the US Justice Department started to research and develops a standard for body armor performance. Finally, after many revisions, changes and updates, a standard for body armor has emerged which is known today as the National Institute of Justice (or NIJ) standard 0101. The NIJ standard was implemented in 1987 and is the main standard used and recognized today by most countries. This standard covers many aspects of the design; manufacture and testing of ballistic body armor. This test standard coupled with stringent quality control, allows the wearer to have confidence that their body armor will perform to its started rating. Type 1, type 2a, type 2 and type 3a are all part of the soft body armor level while type 3 and type 4 are hard plates designed to defeat projectiles at rifle speeds and in most instances must be used in conjunction with the soft body armor tested specifically for that combination. This is one of the differences of type 3 and type 3a body armor. Again, type 3a is a soft body armor while type 3 is a hard body armor. The inclusion of a + after the threat level (i.e. IIIA+) indicates that the body armor was tested for an additional caliber as well as those specified in the N.I.J. standard for that threat level. The higher the threat level protection of body armor, the heavier and thicker the body armor becomes. Type 3 body armor is a hard plate style of armor and is used in conjunction with soft body armor to give protection against rifles while type 3a body armor has usually provides the highest level of protection among those concealable bullet proof vests. This is usually worn as overt style armor because of the weight and thickness of the ballistic panels. However with the development of new materials and lighter fabrics, is has become viable for covert use. |
