Ballistic Levels

Our cars: How we develop bullet proof

There are a number of factors to consider in ensuring the quality of a bullet proof car. The list includes the various threat levels that you might face, and the capability of your vehicle to withstand these threats in a chance encounter. However, to have a better understanding of bullet-resistant classification, it is important to first have a solid grasp of the international standards and classifications used to measure vehicle readiness in dire situations.

Bullet resistance for windows and doors:

EN 1063, or CEN viagra feminin avis canada 1063, is an international standard developed by the European Committee for Standardisation designed to measure the capability of reinforced glass to withstand ballistics. It is utilised in tandem with the EN 1522, which is the international standard for measuring the overall protective strength of windows, shutters, doors, and blinds. These standards are used to test, rate, and determine the ballistic classification of bullet proof cars.

The United States has developed its own counterpart of this classification method named the NIJ Standard 0108. The Standard for Ballistic Resistant Protective Materials developed by the U.S. National Institute of Justice covers glass and armour plating as well.

How is a car rated for bullet resistance?

Glazed shielding is rated and classified according to the type of ballistic munitions that it is able to withstand. Under the European standard, there are 7 standard munitions that security glazing can repel, ranging from a .22 LR bullet to a 7.62×51mm NATO bullet. In addition, there are two other threat levels that are used to classify shotgun munitions.

To classify, bullet proof cars must be able to withstand a particular munition type from penetrating the shell for a particular number of shots. Each shot will be placed within 120 mm of each other. One particularly important factor is the ability of the glazing to keep from shattering and producing spalls after each strike.
