[11] When projectiles do not penetrate, the depth of the dent left by the impact can be measured and related to the projectiles velocity and thickness of the material. Well, there's no demand for such a product. [4], An impact on polycarbonate by a projectile at temperatures below 7C sometimes creates spall, pieces of polycarbonate that are broken off and become projectiles themselves. Standard issue .50 cal cartridges generally have a 700 grain bullet (that is, one three times heavier than a .44 Mag) that travels at 3,000 fps (three times faster than a jet fighter), with a muzzle energy exceeding 13,000 foot-pounds (more than thirteen times that of a .44 Mag). Secure Mobile India Nangloi, New Delhi TrustSEAL Verified Company Video View Mobile Number The plastic provides little in the way of bullet-resistance. Bullet-resistant materials are tested using a gun to fire a projectile from a set distance into the material, in a specific pattern. Customized bulletproof glass This type of ballistic glass is generally custom manufactured. This sticker indicates that the manufacturer submitted samples to Underwriters Laboratories, the nations leading third-party product safety certification agency. According to Jim, youre looking at an awful thick, awful big, and awful heavy hunk of bullet resistant glass. Incidentally: the fastest projectile speed is 950 m/s. Level 2 is similarly used in customer-facing facilities but is typically designated for buildings with more severe security threats such as banks and jewelers. The index of refraction for all of the glasses used in the bulletproof layers must be almost the same to keep the glass transparent and allow a clear, undistorted view through the glass. With all the material types above, thickness is what matters most. 9mm 124gr @ 1175-1293fps (1400-1530fps for Level 6), 357M 158gr @ 1250-1375fps, 44M 240gr @ 1350-1485fps, 30-06 180gr @ 2540-2794fps, 5.56NATO 55gr @ 3080-3388fps, 7.62NATO 150gr @ 2750-3025fps.

The Uzis, M16s, and AK-47s used for the Level 5 through 8 tests are notorious for their lethal full-auto fire, and therefore pose the highest potential threat to human life. Bullet proof glass vs. bullet resistant glass: Know the difference. These are implemented in the highest risk applications where the added material costs are justified by the level of threat. Previously only seen in the battlefield, these half-inch-diameter bullets (nearly the size of a 12-gauge shotgun slug) were first adapted to sidearms in the 1980s, and popularized by the semi-automatic Desert Eagle target pistol. 77% visible light transmittance. Ballistic or Bullet Glass. As Total Security Solutions vice president Jim Richards explains, the .30-06 bullet is 180 grains of lead moving at 2540 feet per second. Answer (1 of 3): Per UL Standards, this would be defined as Level 10 bullet resistance. Level(china) Gun type Bullet types. Whats even crazier: the Level 4 test is actually harder to pass than Levels 5, 6, or 7. Resists .44 Magnum round, no spall on asset side. If the polycarbonate layer is below a glass layer, it has some protection from UV radiation due to the glass and bonding layer. HC1 Steel hard core, mass 3.7g +/-0.1g, Hardness larger than 63 HCR, SCP1 Soft-centre (lead) with steel penetrator (type SS109), RC2 glass for RC3 glazing for panic doors. Lets simplify things: In order to pass the Level 4 ballistics test, bulletproof glass must stop one shot from a .30-06 hunting rifle. The MarketWatch News Department was not involved in the creation of this content. There is Level-10 rated bullet resistant glass. Eight different levels of ballistics resistant glass have been established by the UL, each capable of withstanding security threats of different magnitudes. Level 3 bullet resistant glass is preferred for larger facilities where threat levels are typically more severe. Bulletproof glass is used in windows of buildings that require such security, such as jewelry stores and embassies, and of military and private vehicles. Why? The more layers there are, the more protection the glass offers. Contents 1 Construction 2 Test standards 3 Environmental effects 4 2000s advances 4.1 Spinel ceramics The most common military .50 caliber bullet is the US Browning machine gun round. U.S. National Institute of Justice (NIJ) standard resistant protective materials (NIJ Standard 0108.01). Bulletproof glass varies in thickness from 34 to 312 inches (19 to 89 mm). The revolvers chambered for these finger-sized cartridges are almost cartoonishly massive, even when compared to Dirty Harrys hefty long-barrel Model 29. Level 5 can be difficult, but still, its one shot of a 7.62 [just a touch heavier than a 9mm]; so its moving faster, but its a lot lighter. A good Level 4 system can often pass the tests for Levels 5, 6, and 7 with little or no modification and might even pass the Level 8 test (a five-shot burst from an AK-47). [3], Laminated glass layers are built from glass sheets bonded together with polyvinyl butyral, polyurethane, Sentryglas, or ethylene-vinyl acetate. The more layers you have, the more protection you have. .50 Cals and Level 10 Bullet Resistant Glass. Nominal Thickness. Level 8 bullet resistant glazing also available. EN 13541 Blast Resistant Glazing. The level of the bullet resistance of the glass determines how much protection it will provide based on the gun, ammunition, and the number of shots. Over time the polycarbonate becomes more brittle because it is an amorphous polymer (which is necessary for it to be transparent) that moves toward thermodynamic equilibrium. The eight ballistics grades are self-explanatory provided that you know details like 7.62mm ammunition is used in an AK-47, 5.56mm ammo in an M16, and that .30 caliber rifle lead core soft point basically means a hunting rifle. The UL rating system is a series of tests established by the Underwriters Laboratory (UL), a not-for-profit organization focussed on enhancing public safety by founding sets of standards for various products. Color. It's ability to protect against these threats depends on its Underwriters Laboratory 752 Level (1-10), or UL Level for short. This glass is designed to stop a 50cal lead core round shot from a rifle. 2022 Total Security Solutions. So if a system can withstand the three bullets in the Level 1 test, its likely it will be able to stop at least two more.

It has been suggested that a second inner layer of polycarbonate may effectively resist penetration by the spall. Move up to Level 4, and you can stop a .30-06 hunting rifle bullet (the little cousin to the .50 caliber military round); this is a 180 grain bullet (clearly much lighter than the .50 cal pistol round) with 3,000 foot-pounds of energy (twice as much as the .50 cal pistol) moving at almost 2,800 feet per second (again, nearly twice as fast as the .50 caliber Magnum bullet). This might seem easier than the Level 3 test since its just a single, lighter bullet. The rank is based on thickness, number of layers, and certified testing. Gas Checked: 3: Level 4: 30 Caliber Rifle Lead Core Soft Point(.30-06 caliber) 1: Level 5: 7.62mm Rifle Lead Core Full Metal Copper 1 Jacket, Military Ball (.308 caliber) 1: Level 6: 9mm Full Metal Copper Jacket with 5 Lead Core: 5: Level 7 Most commonly used as a protection barrier against high-power military hunting and sporting rifles, such as the 30-06, and the like, with muzzle energy of 2580-3120 foot-pounds (3498-4929J). Armortex has been manufacturing Bullet, Blast and Forced Entry Resistant products for more than thirty years. UL752 Level 3 bullet resistance. [14][15], Certain types of ceramics can also be used for transparent armor due to their properties of increased density and hardness when compared to traditional glass. It is typically thick and is usually extremely heavy.[6]. At PRL we render laminated glass for threat levels 1-8. Bullet resistant glass is designed to stop projectiles without shattering, absorbing their energy and retaining the bullet. Level 6: Is a direct improvement on Level 1, designed to withstand at least five 9mm rounds traveling at an elevated minimum velocity of 1400f/s. Firing tests:In the firing tests in accordance with EN 1063, the bullet-resistant glass (500 x 500 mm) to be tested is fastened in a frame. The problem is that officially there aren't any commercially available bullet-resistant systems rated for level 10 protection. It defines bullet resistant glass that can withstand at least one shot from a .30 caliber rifle with a minimum velocity of 2540f/s. Develop an understanding of the various levels of protection, as well as how to specify these products for a project. The stopping power is directly proportional to the thickness. Guaranteeing the specified level of protection requires a testing methodology that can reconcile each of these dynamic factors. [4], In 2005, it was reported that U.S. military researchers were developing a class of transparent armor incorporating These types of synthetic ceramic transparent armors can allow for thinner armor with equivalent stopping power to traditional laminated glass. Developed in the early 1900s, these are still regularly deployed in the battlefield as a standard full-metal jacket, tracer, or armor piercing bullet, as well as exotic incendiary and saboted sub-caliber projectiles (the latter offering superior accuracy over extremely long distances). Level 2 barriers will stop three shots from a .357 Magnum (heavier ammunition moving at higher velocity). Guarding against a volume of weaponry and ammunition, our bullet resistant glass is perfect for entrance doors, cashier windows, and more. Think banks, airports, and gas stations. Such a rifle costs $12,000 and fires rounds that cost $2 to $5 a piece. There are two most common types of resins used for bullet-resistant glass, acrylic and polycarbonate plastic. 3: Level 3: 44 Magnum Lead Semi-Wadcutter 3. Blast Protection. BS EN1063 Ballistic or Bullet Glass. Heres how: the Level 6 Uzi test is a five-shot burst of the same 9mm ammunition used in the Level 1 test. [5] Some researchers have developed mathematical models based on results of this kind of testing to help them design bulletproof glass to resist specific anticipated threats.[12]. UL Rating Level 8. A .50 cal pistol weighs in around five pounds, and is almost a foot-and-a-half long from hammer to muzzle. This solution stops the bullets in a totally different way. That's at least 3,400 km/h. TSS experts are here to help . Provides protection against five shots of a 124-grain 9mm full metal copper jacket with lead core at an fps between 1400 and 1540.

Level 7: Defines bullet resistant glass designed to withstand multiple hits with 5.56 rifle FMJs with a minimum velocity of 3080f/s. Semi-automatic .30-.06 rifles are rare, and the long-barreled rifle is designed for accuracy over distance, making it difficult to use in the close confines of a gas station or bank. The following table shows the weapons and ammunition types used for testing of bullet-resistant glass in accordance with EN 1063. If no glass splinters emerge on the protective side, the ballistic class additionally receives the rating "no splinters" (NS= no splinters). of Shots 3 UL 752 Paragraph 4.3 Ammunition Tested 9mm full metal copper jacket with lead core - 124 grain, 8 grams, minimum 1175 feet per second. Experiments suggest that polycarbonate fails at lower velocities with regular shaped projectiles compared to irregular ones (like fragments), meaning that testing with regular shaped projectiles gives a conservative estimate of its resistance. This fact implies that, despite the Level 4 deer-hunting rifles acrylic-shattering power, its an uncommon personal weapon and has a lower rating. The ability of the polycarbonate layer to stop projectiles with varying energy is directly proportional to its thickness,[5] and bulletproof glass of this design may be up to 3.5 inches thick. They are used most by small businesses looking to deter crime. Would Jim feel safe standing behind Level 4 bullet resistant glass? A brief explanation of each level follows: These ballistics grades are generally grouped together for distinct applications. The European standard EN 1063 regulates the testing procedure for bullet-resistant glass in 9 different ballistic classes. Bulletproof glass application. It's worth noting that as thickness increases, so does the weight, which is something that must be considered in building design and renovation projects. For all ratings in the above chart; all copper-jacketed lead FMJ, except 44 mg is lead semi-wadcutter gas-check, and 30-06 is LEAD core soft point. But that bullet is designed for penetration, and it travels 1200 feet per second faster than the .44 Magnum. Products for all levels of protection to recognised standards. Dig deep into the UL standards and youll find that there is an established benchmark for stopping the .50 caliber military round: Level 10. This level is tested to withstand at least five shots from a 7.62mm rifle. UL specification for commercial bullet resistant glass. The deformed bullet completely penetrates the glass and then it is stopped by the flexible polycarbonate. Bullet-resistant glass is constructed using layers of laminated glass. These layers are bound together through a chemical process, thereby strengthening it enough to absorb the impact of a bullet or blast. The vast bulk of consumer .50 cal rifles are in the collections of extremely wealthy gun enthusiasts; according to the US General Accounting Offices best estimate as of 2001, only a few thousand .50 cal rifles are floating around the United States.
