You may often hear NIJ think that this is the global standard bulletproof standard. In fact, it is not. This is only the American bulletproof standard. Do you want to know how other countries judge the bulletproof standard?
Let’s discuss it today!
This article is popular science in nature. It is too difficult to understand and unnecessary to understand the data. Let’s not talk about it first.
Words you may not know:
Back concave depth: the concave depth of the back of the bulletproof clothing after being impacted and deformed by the warhead. The greater the depth, the more likely the user is to “break the rib”.
FMJ / fmsj bullet: all metal armor bullet, an ordinary bullet.
JSP / sjsp bullet: semi armour soft tip bullet, the so-called “dum bullet”, a kind of ammunition that sacrifices armor piercing performance in exchange for lethality to soft targets (human body).
Jhp / sjhp projectile: semi armour air pointed projectile, similar to dum projectile, but with stronger soft target killing ability than dum projectile.
FMS bullet: all metal pointed bullet, a German pistol bullet with conical warhead, which has stronger armor piercing ability.

U.S.A

You may be familiar with American standards, but we will review them in more detail today
1) NIJ 0101.06 standard:
NIJ 0101.06 standard is formulated by the National Institute of justice for the needs of bulletproof vests of law enforcement agencies. The latest version 6 standard was formulated in 2008 and will be replaced by NIJ 0101.07 standard in 2021.
Due to various reasons, this national standard has become the most widely known standard in the world, worthy of “home of the brake, land of the freedom”.

In addition, although it is very famous, this standard is still used by American cops after all. It is relatively insufficient in the military field.
The NIJ standard has the deepest back recess of all standards.
The depth of back recess shall not exceed 1.73inch/44mm.
Type IIA: capable of blocking 9 * 19mm round head FMJ projectile and. 40 S & W FMJ projectile.
Type II: it can block 9 * 19mm round head FMJ bullet and. 357 magnum JSP bullet.
Type IIIA: capable of blocking. 357 sig flat head FMJ bullet and. 44 magnum sjhp bullet.
Type III: capable of blocking 7.62 * 51mm FMJ (US military number M80) projectile.
Type IV: able to block. 30-06 M2 armor piercing projectile.
2) NIJ 0106.01 (modified) standard:
NIJ 0106.01 standard is a standard to measure the bulletproof performance of helmets, which was established by the National Institute of justice in 1981. In order to save the old regulations that can not keep up with the times, they made some modifications to it at a certain time point and added IIIA level.
Type I: able to block. 22 LR high-speed lead bullets and. 38 special round headed lead bullets.
Type IIA: it can block 9 * 19mm round head FMJ bullet and. 357 magnum JSP bullet fired by 4 ~ 4.75 inch barrel.
Type II: it can block 9 * 19mm round head FMJ bullet and. 357 magnum JSP bullet fired by 6 ~ 6.75 inch barrel.
Type IIIA: capable of blocking. 357 sig flat head FMJ bullet and. 44 magnum sjhp bullet.
3) American bulletproof clothing standard
Although the US military’s bulletproof vests still use the NIJ rating, the US military has additional requirements for different batches of bulletproof vests and bulletproof inserts during procurement.

These requirements are more scientific, and there is refinement and further improvement of performance indicators, which is more mature than the simple NIJ standard.

Chinese GA 141-2010 Standard:

The next step is the Chinese standard, which is completely different from that of the United States. It pays more attention to what types of bullets are targeted by different protective plates, which can make you find the protective articles you need more concretely.
On October 17, 2010, the Ministry of public security of the people’s Republic of China issued the GA 141-2010 standard for police bulletproof vests instead of GA 141-2001, standardized the types of bullets used in the test and modified the requirements for the protective area of bulletproof vests. The specific contents will not be repeated here.
The depth of back recess shall not exceed 25mm.
Level 1: able to block 7.62 * 17mm lead pistol bullet.
Level 2: able to block 7.62 * 25MM lead pistol bullet.
Level 3: 7.62 * 25MM lead pistol bullet that can block the firing of 79 submachine gun with long barrel.
Level 4: 7.62 * 25MM steel core pistol bullet that can block the firing of type 79 submachine gun with long barrel.
Level 5: able to block 7.62 * 39mm 56 ordinary ammunition.
Level 6: able to block 7.62 * 54mm 53 ordinary ammunition.

Russia

Next, Russia is introduced. The Russian standards are clearer, but their evaluation standards are almost transplanted from the old Soviet Union.

1) Gost R 50744-95 old standard:
A relatively detailed measurement system, which is used by various bulletproof equipment in takovri.
I have Russian materials, but I can only copy en wiki because I can’t understand Russian. If I can speak Russian and am willing to contribute some time to help me expand this introduction, please leave a message below.
The depth of back recess shall not exceed 16mm.
Class 1: capable of blocking 9 * 18mm Makarov (57-n-181s) projectile and 7.62 * 38mm Nagan revolver projectile.
Class 2: able to block 5.45 × 18mm mpts 7n7 bullet and 7.62 * 25MM tokalev bullet
Class 2A: able to block No. 12 shotgun.
Class 3: able to block 5.45 × And n397.7 mm steel core × 39mm 57-n-231 hard steel core bullet.
Class 4: able to block 5.45 × 39mm 7n10 armor piercing reinforced hard steel core bullet.
Class 5: able to block 7.62 × 54mmr 57-n-323s hard steel core bullet and 7.62 × 39mm 57-n-231 hard steel core bullet.
Class 5A: capable of blocking 7.62 × 39mm 57-bz-231 (BZ API) armor piercing incendiary bomb.

Class 6A: capable of blocking 7.62 × 54mmr 7-bz-3 (B32 API) armor piercing incendiary bomb.
2) Gost R 50744-95 new standard:
The new standard implemented in 2017 integrates and removes some overly cumbersome old standards, and adds two new bulletproof levels – the BR6 standard is really outrageous. I really didn’t expect that the Russians have developed bulletproof vests that can block 12.7 * 108mm without killing people after running a few steps.
The depth of back recess shall not exceed 16mm.
BR1: capable of blocking 9 * 18mm Makarov (57-n-181s) projectile.

BR6: able to block 12.7 × 108mm 57-bz-542 armor piercing incendiary bomb.

Britain

Now Its Britain,Lets see what we cant

1) British hosdb standard (2007 Edition):
The hosdb standard was first formulated by the home office scientific development branch of the UK Ministry of the interior in 1993. Similar to the NIJ standard, it is designed to provide protection for the English police, but different from the NIJ 0101.06 standard, the hosdb standard also covers the anti stab standard for cold weapons such as props and spears.
Only the bulletproof standard part of hosdb is excerpted here.
In 2003, the Scientific Development Department of the Ministry of the interior increased the bulletproof level of Hg1 / A, which is completely consistent with Hg1 except that the upper limit of the back concave depth was raised to 44mm.
Except that the upper limit of back concave depth of Hg1 / A is 44mm, the other back concave depth shall not exceed 25mm.
Hg1: capable of blocking 9 * 19mm FMJ bullet and. 357 magnum JSP bullet.
Hg1 / A: capable of blocking 9 * 19mm FMJ bullet and. 357 magnum JSP bullet.

HO2: it can block 9 * 19mm FMJ bullet and 9 * 19mm jhp bullet (higher initial velocity of warhead is required, which can be understood as pistol bullet fired by submachine gun / PCC with long barrel). The average back concave depth shall not exceed 25mm, and the maximum back concave depth shall not exceed 44mm.
Ho3: capable of blocking 7.26 * 51mm NATO (l44a1 or l2a2) bombs and 7.62 × 39mm bullet. The average back concave depth shall not exceed 25mm, and the maximum back concave depth shall not exceed 30mm.

German TR Standard:

Tr (Technische richtlinie) in Germany was proposed in 2008 and developed based on vpam standard, which may be the most common test standard in Europe. The biggest difference between it and NIJ standard is that tr standard will test pistol armor piercing bullet, while NIJ will not.
I can’t understand German information, so I picked it up from several English websites + en wikis. If you know German and are willing to contribute some time to help me expand this introduction, please leave a message below.
The depth of back recess shall not exceed 42mm.
