level 4 body armor stopping power
The Nemean Series Level IIIA is our answer to making you impervious to attack in an extremely lightweight and thin ballistic package. After the Vietnam War, military planners developed a concept of "Casualty Reduction". This armor b alances weight, protection, and concealability. AR500 Armor Level IV (Ceramic/PE) Body Armor. MilSpec vs. AR500. The "backface signature," or transmitted impact energy, is measured by shooting armor mounted in front of a backing material, typically oil-based modeling clay. 10.2 g (158 gr) .357 Magnum Jacketed Soft Point bullets at a velocity of 436 m/s Â± 9.1 m/s (1430 ft/s Â± 30 ft/s). Soft Body Armor NIJ Threat Levels NIJ Level iia. The ballistic tests to determine a class are now integrated into the VPAM guidelines, so that the tests differ just in minor details and only one test (SK 1) is significantly different as of 2008.. Ballistic testing has a number of sources of variability: the armor, test backing materials, bullet, casing, powder, primer and the gun barrel, to name a few. And you'd be correct, at least dimensionally.  The allowable backface signature for body armor has been controversial from its introduction in the first NIJ test standard and the debate as to the relative importance of penetration-resistance vs. backface signature continues in the medical and testing communities. Sizes for any E/SAPI designated plate range from Extra Small (7.25 x 11.50 inches) to Extra Large (11.â¦ Over 120,000 inserts were procured; Back face signature measurement. SK 4). The second part of "Casualty Reduction" strategy is a study of velocity distributions of fragments from munitions. Provides dynamic view of event. Click now to learn more. Providing training programs that demonstrate body armorâs stopping power under actual fir - My ID is 15I-01-384. This is the velocity at which 50 percent of the shots go through and 50 percent are stopped by the armor. In addition, special requirements can be defined under this process for armors for flexible rifle protection, fragment protection for the extremities, etc. It specifies five different classes ranging from L to 4 of ballistic protection (e.g. .22 rimfire to 12 Gauge Vintage Outdoors: Visual Chart Detailing The Stopping Power of Different Levels of Body Armor With Ammo Examples These military procurement requirements do not relate to NIJ, HOSDB or ISO law enforcement armor standards, test methods, garment size, projectiles or velocities. This history helps explain an important factor in Ballistics and Stab armor testing, backing stiffness affects armor penetration resistance. Mostly worse. It offers protection from: 30.06 M2 AP - 2868 fps; 7.62 x 39 - â¦ This armour may come in a soft form, as worn by many police officers, prison guards, security guards and some private citizens (e.g. While there are many different standards for ballistics protection levels, the two most commonly recognized standards for body armor come from the US National Institute of Justice (NIJ) and the UK Centre for Applied Science and Technology (CAST, formerly HOSDB). Only if the bullet is hitting you at an angle will a 3A rating stop larger rounds like 7.62 and 5.56. With the rise of terrorist acts in the US, the need for police officers and law abiding citizens to protect themselves is more prevalent now than ever before. We start back with the AR500 armor series because they are that good. 8.1 g (125 gr) .357 SIG FMJ Flat Nose (FN) bullets at a velocity of 448 m/s Â± 9.1 m/s (1470 ft/s Â± 30 ft/s), 8.1 g (125 gr) .357 SIG FMJ Flat Nose (FN) bullets at a velocity of 430 m/s Â± 9.1 m/s (1410 ft/s Â± 30 ft/s), 2-grain (0.13 g) RCC (Right Circular Cylinder) at a velocity (V, 4-grain (0.26 g) RCC at a velocity of 2,400-foot-per-second (730 m/s) (V, 16-grain (1.0 g) RCC at a velocity of 2,050-foot-per-second (620 m/s) (V, 64-grain (4.1 g) RCC at a velocity of 1,660-foot-per-second (510 m/s) (V, 16-grain (1.0 g) RCC at a velocity of 2,000-foot-per-second (610 m/s) (V, 16-grain (1.0 g) RCC at a velocity of 1,900-foot-per-second (580 m/s) (V, 17-grain (1.1 g) Fragment Simulating Projectile (FSP) at a velocity of 1,850-foot-per-second (560 m/s) (V, Using Roma clay backing, only metallic stab solutions met the 109 joule Calif. DOC ice pick requirement. New armor protects against 8 g (124 gr) 9 mm FMJ RN bullets at a velocity of 398 m/s ± 9.1 m/s (1305 ft/s ± 30 ft/s) and 10.2 g (158 gr) .357 Magnum Jacketed Soft Point bullets at a velocity of 436 m/s ± 9.1 m/s (1430 ft/s ± 30 ft/s). This test is based on VPAM PM 3, but it adds two police special rounds, with the following modifications: This armor would protect against five hits, fired from 5 meters, of: This armor would protect against three hits, fired from 5.10 meters, of: This armor would protect against five hits, fired from 5Â±0.1, meters of: This armor would protect against five hits, fired from 5Â±0.1 meters, of: This armor would protect against three hits, fired from 10Â±0.1 meters, of: This armor would protect against three hits, fired from 50Â±0.5 meters, of: US Army soft armor inserts adhere to standards specified under FQ/PD 07â05. NIJ level II testing on deck with 9mm, 40 S&W, 12ga 00 buckshot, 7.62x39, and 223 Remington rounds. For vest manufacturing, field evaluation and life testing both v0 and v50 are used. Assessing weapons and ammunition currently in use and the suitability of approved body armor to protect against those threats. Certain body armor is an excellent barrier for knife attacks. Made from advanced PEUD Dyneema® and a patented woven aramid, these ballistics are NIJ compliant âCertifiedâ and special threat tested to â¦ Thickness/number of layers directly correlates to âstopping power.â However, bullet-resistant materials tend to be heavy, especially in as-manufactured armors. ... 4) You can be choked out on your body armor. As each country has regional threats which may be unique to it, some standards may include threats that are not present in others. If for example, the v0 of an armor design is measured to be 1,600 ft/s (490 m/s) with a 9 mm FMJ bullet based on 30 shots, the test is only an estimate of the real v0 of this armor. Prior to the 2017 revision, the threat levels ran from 1 to 6. This armor would protect against three hits, fired from 5Â±0.5 meters, as well as point-black shots, of: This armor would protect against three hits, fired from 5Â±0.5 meters in an angle of 25Â°, as well as 3 shots at point-blank, of: The German TR are generally comparable to the American NIJ, but the German TR usually tests more threat scenarios, as there are no point-black shots as well as no police special rounds. These three high stops and three low penetrations can then be used to calculate a v50 velocity. While it may appear otherwise, there are very few "guaranteed" spawns - most of the time, you will find a power armor frame with randomly generated, level-dependent pieces present.  This new standard will completely replace the NIJ Standard-0101.06. This program features plates designed to military specs. In practice this measurement of v50 requires 1â2 vest panels and 10â20 shots.  Warhead explosives have blast speeds of 20,000 ft/s (6,100 m/s) to 30,000 ft/s (9,100 m/s). Away from the rib cage and spine, the soft tissue behavior is soft and compliant. Best Ceramic Level IV Body Armor. 8 g (124 gr) 9 mm FMJ RN bullets at a velocity of 398 m/s Â± 9.1 m/s (1305 ft/s Â± 30 ft/s). Level IV (i.e., Level 4) is tested to stop one hit of .3006 AP, and will easily stop â¦ Thanks. It also provides protection against the threats mentioned in [Types I, IIA, II, and IIIA]. For the NIJ Standard-0101.07, the velocity for both conditioned and new armor will be the same. This NIJ study on vests returned from the field demonstrated that environmental effects on Zylon resulted in ballistic failures under standard test conditions.. The more shots made the lower the v0 will go. 5.56 knockdown power vs level III or IV armor Hello everyone, I have a good deal of experience with firearms, I just recently purchased my first rifle, an M&P 15 sport. From levels 3 and 4, you can only find body armor that uses hard ballistic plates. If this offset has been measured for an armor design, then v50 data can be used to measure and estimate changes in v0. The 2-grain (0.13 g) FSP (the smallest fragment projectile commonly used in testing) is about the size of a grain of rice; such small fast moving fragments can potentially slip through the vest, moving between yarns. They have a black fabric cover with white text. This concluded that water, long-term use, and temperature exposure significantly affect tensile strength and the ballistic performance of PBO or Zylon fiber. Producers have to meet the criteria of the TR, if they want to participate in open competitive bidding made by German agencies. There are two basic classes of body armor. Below are some of the most common rounds, the most popular rounds, and the most famous rounds available, and what level of body armor you will need to protect against each. The first is known as âsoft body armorâ and is what most cops wear under their uniform shirts. level-3-body-armor $65.00 Our flagship body armor, Level III is rated to stop six rounds of 7.62x51 M80 NATO Ball ammunition @ 2,780 fps, and special threat tested to stop 5.56mm M855/SS109 (Green Tip) at a velocity of 2,780 fps. Stab resistance is broken down into âedged bladeâ and âspikeâ designations. Although the US military requirements for body armor mirror the NIJ's on a surface level, the two are very different systems. We start back with the AR500 armor series because they are that good. In contrast the NIJ tests for bigger calibers and higher man stopping power. These plates are rated to stop the following threats: ESAPI plates were developed in response to increased threats posed by 7.62x54mmR AP threats in Iraq and Afghanistan. Not in the sense that leaving a bottle of lotion on the coffee table and playing âGoodbye Horsesâ is a terrible way to impress a date, but it also isnât what most of the breathless fanbois are fainting over, either. Most recently the Draft ISO prEN ISO 14876 norm selected Roma as the backing for both ballistics and stab testing. $220.00. According to VPAM's website, it is apparently used in France and Britain. Now, I understand that the penetration largely depends on the projectile type and a high-explosive armor-piercing incendiary projectile would probably zip through and tear apart this armor plate. These levels are available in both âhardâ and âsoftâ form. Our Level IV rifle rated hard armor plates are independently tested to NIJ protocol and developed to defeat a single shot of 7.62×63 APM2 at muzzle velocity. and has the industry's best stopping power. This shape has a length equal to its diameter. Hello My name is Fred Martell and I am a Canadian Firearms Course Safety Instructor for Nova Scotia, Canada. Used for most standard testing, Good simulant for human tissue, hard to use, expensive. Home / Body Armor / Level IV / Level IV Hard Armor Plate SET of 2 (Model #1155) NIJ .06 Certified. Part II. HG is for soft armor and RF is for hard armor. Stab resistance is broken down into âedged bladeâ and âspikeâ designations. NIJ standards are used for law enforcement armors. AMI's BZ Special Threat Level measures 11.4" X 9.5", weighs just 4.8 lbs. Stopping Power Rating System (Threat Level of Protection) All types of body armor are rated by the National Institute of Justice Standards (0101.06) for protection levels of safety (ie. Not affiliated in any way but I had been looking for a reasonable alternative to the super expensive and ubiquitous body armor available and came across them. This armor would protect against three hits, fired from 10Â±0.5 meters, of: This armor would protect against three hits, fired from 5Â±0.5 meters, of: This armor would protect against three hits, fired from an arbitrary distance, of: This test is based on VPAM PM 2, but it tests also for point-blank shots. Because the energy of a bullet is a key factor in its penetrating capacity, velocity is used as the primary independent variable in ballistic testing. ISAPI (Improved SAPI) plates were designed as an upgrade to SAPI in the face of API threats in Iraq. They saw first use with the Interceptor carrier system, followed by the IOTV (Improved Outer Tactical Vest) and MTV (Modular Tactical Vest). When you need Rifle Plates WITHOUT a soft Body Armor vest underneath, you need a Stand-Alone Rifle Plate. For most users the key measurement is the velocity at which no bullets will penetrate the armor. Our flagship body armor, Level III is rated to stop six rounds of 7.62x51 M80 NATO Ball ammunition @ 2,780 fps, and special threat tested to stop 5.56mm M855/SS109 (Green Tip) at a velocity of 2,780 fps. Textile armor is tested for both penetration resistance by bullets and for the impact energy transmitted to the wearer. Anything below Level IV body armor will not stop or even significantly slow down a 30.06. In contrast the NIJ tests for bigger calibers and higher man stopping power. US military standard MIL-STD-662F V50 Ballistic Test define a commonly used procedure for this measurement. Using 10% Gelatin backing, all fabric stab solutions were able to meet the 109 joule Calif. DOC ice pick requirement. .22 rimfire to 12 Gauge Vintage Outdoors: Visual Chart Detailing The Stopping Power of Different Levels of Body Armor With Ammo Examples I was wondering if it would be possible to obtain a copy of yours “Stopping power of body armor diagram” It would be a great asset for my Power Point presentation ad of course if it was a wall chart it would be a very interesting for our students (usually 24 per class.) Like the AR500 steel plates, you can find their ceramic plates in a variety of cuts and sizes. Which pieces spawn is determined by your character level â¦ The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. It is vital when choosing body armor to make sure that it adheres to the proper protection levels. In contrast to the design of vest for deformable lead bullets, fragments do not change shape; they are steel and can not be deformed by textile materials. Moderate agreement with tissue, easy to use, low in cost. 10. Used in stab testing, Biomedical testing for blunt force testing, very good tissue match, Very complex, requires ethical review for approval, 35 g (540 gr) 12 gauge lead-core "Hunter" shotshells at a velocity of 390â410 m/s (1279â1345 ft/s), 8 g (124 gr) 9 mm FMJ RN bullets at a velocity of 355 m/s Â± 9.1 m/s (1165 ft/s Â± 30 ft/s), 11.7 g (180 gr) .40 S&W FMJ bullets at a velocity of 325 m/s Â± 9.1 m/s (1065 ft/s Â± 30 ft/s). The use of harder Roma materials in the ISO draft norm makes this the most rigorous of the stab standards in use today. AR500 Level IV Ceramic. No bullets got through the plate. In addition to the NIJ and HOSDB law enforcement armor standards, other important standards include German Police TR-Technische Richtlinie, Draft ISO prEN ISO 14876, and Underwriters Laboratories (UL Standard 752). If you want the best protection possible or specifically care about protection against very high powered or armor piercing rounds (like the uncommon .30-06 AP black tip), go level 4. It also gives specifications for additional Stichschutz (ST), protection against knives, using the same classes as the ballistic protection, but giving it the additional ST label (e.g. In spite of the more difficult test threats, the 16mm back-face deformation limit remains unchanged.. Skip to the beginning of the images gallery This rating is meant to stop .44 Magnum Jacketed Hollow Points traveling at 1400 feet per second. This is a guest post by Andrew Betts Okay, so it isnât terrible exactly. The two systems share a 44mm limit on back-face deformation, but SAPI-series plates increase linearly in protection (with each plate tested against the preceding plate's threats), and require a soft armor backer in order to reach their stated level of protection. In general a vest's textile material temporarily degrades when wet. Yes, as unbelievable as it is, this body armor managed to stop the .50 BMG bullet at such a close distance. By adding a ceramic face, polyethylene plates can be certified to Level IV and will stop steel core and tactical rifle rounds up to and including 166-grain .30 caliber M2 armor-piercing. When the force is reduced by a softer more compliant backing the armor is less likely to be penetrated. If the variability is known and the standard deviation can be calculated, one can rigorously set the V0 at a confidence interval. A ballistic vest or bullet-resistant vest, often called a bulletproof vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from firearm-fired projectiles and shrapnel from explosions. .375 SIG : This round is nearly identical to the .357 Magnum. My ID is 15I-01-384. This complexity requires very elaborate bio-morphic backing material systems for accurate ballistic and stab armor testing. Only a single low velocity penetrating shot is required to reduce the v0 value. For the $20~30 bucks I spent building this DIY body armor it was money well spent.  (Armor placed over a harder surface is more easily penetrated.) In the latest video published on the channel, Jerry tests a Veterans MFG Ultralight Level III+ body armor by shooting a .50 BMG Hornady 750 grain A-Max bullet at that plate. For example, for NIJ Standard-0101.06 Level IIIA the .44 Magnum round is currently shot at 408 m/s for conditioned armor and at 436 m/s for new armor. The selection of test backing is significant because in flexible armor, the body tissue of a wearer plays an integral part in absorbing the high energy impact of ballistic and stab events. Enjoy the video. This type of armor is classified by threat level (the type of bullets they protect against). While level 4 body armor offers the maximum protection, you and your loved ones likely wonât need to stop 30.06 M2AP armor-piercing bullets, and a lower grade piece of armor would be plenty protective. AR500 Armor Level IV (Ceramic/PE) Body Armor. Now that you know How To Build A DIY Ballistics Plate Body Armor itâs time to destroy it. The updated standards from the 2017 revision are as follows: NIJ Standard-0101.06 has specific performance standards for bullet resistant vests used by law enforcement. I was wondering if it would be possible to obtain a copy of yours âStopping power of body armor diagramâ It would be a great asset for my Power Point presentation ad of course if it was a wall chart it would be a very interesting for our students (usually â¦ This procedure defines a confidence interval of an estimate of v0. NIJ 0101.06 Level IV specifies that the plate must be able to stop .30-06 M2AP at 2,880 fps. In all cases, these materials are placed behind the armor during test impacts and are designed to simulate various aspects of human tissue impact behavior. Variability reduces the predictive power of a determination of V0. Meet the Body Armor That Can Stop Them by Charlie Gao Heavy machine guns and sniper rifles in .50 caliber are some of the most feared weapons for the infantryman on the battlefield. Today, the NIJ rates armor not just for ballistic stopping power but also its ability to protect against blades. Required for FBI test methods. Good simulant for skeletal muscle. These RCC Fragment Simulation Projectiles (FSPs) are tested as a group. Yours in firearm safety, Fred, Next post: The Springfield Armory lawsuit waiting to happen, The Springfield Armory lawsuit waiting to happen. It has the benefit of power over the 9mm, and a more manageable recoil than the 10mm Auto. The military has the SAPI (Small Arms Protective Insert) program. The DOD and MOD armor programs-of-record (MTV for example) procure armor using these test standards. The Target Man offers durable level IIIA body armor that is soft, semi flexible, slim for concealment, and can withstand multiple impacts. They all contain a steel casing that is designed to burst into small steel fragments or shrapnel, when their explosive core detonates. 5725 S. Valley View Blvd Suite #4 Las Vegas, Nevada 89118 TEL: 702-829-4029 Attacks involving firearms have increased thus the demand for NIJ-level 3 body armor capable of stopping high velocity, high power â¦ Of note is the inclusion of special regional threats such as Swiss P AP from RUAG and .357 DAG.  Although harder and less deformable than human tissue, Roma represents a "worst case" backing material when plastic deformations in the oil/clay are low (less than 20 mm).  Tested armor must withstand three hits, spaced 120mm (4.72") apart, of the designated test threat with no more than 25mm of back-face deformation in order to pass. In fact, the stopping power of various calibers depends on the level they are graded at. If you are thinking of buying body armor like a bulletproof vest, aka a Kevlar vest, plate carrier, ballistic vest, or bulletproof clothing in general, keep in mind that you are investing in your safety, and your choice could be the difference between life and death. Understanding the threats that will be faced and the mobility necessary to address the situation is important; and we know budget always comes into the conversation. The most common rifle threats today are not even covered by NIJ standards. This is a test I have been waiting awhile to perform, it took a long time to get the plate in. The energy dissipation of the armor-tissue system is Energy = Force Ã Displacement when testing on backings that are softer and more deformable the total impact energy is absorbed at lower force. But, the Level II vest would fail on blunt trauma impact (the NIJ deems any dent greater than ~1.7" (~44 mm.) It also provides protection against most handgun threats, as well as the threats mentioned in Level II and Level IIA, Conditioned armor protects against 9.6 g (148 gr) 7.62x51mm NATO M80 ball bullets at a velocity of 847 m/s ± 9.1 m/s (2780 ft/s ± 30 ft/s). It was issued during WWII originally as special purpose ammunition, as is typically the case with armor piercing ammo, but eventually replaced M1 .30 caliber FMJ due to its superior performance. In terms of statistics, the zero penetration velocity is the tail end of the distribution curve. Best Ceramic Level IV Body Armor. With the rise of terrorist acts in the US, the need for police officers and law abiding citizens to protect themselves is more prevalent now than ever before. 2. Plus, both are â¦ It also provides protection against most handgun threats, as well as the threats mentioned in [Types I, IIA, and II].
