Ballistic research

Kimmelux bullet resistant glazing and steel are in accordance with the most important international ballistics standards. Glazing EN 1063, Stanag 4569 and steel PM2000, EN1522, Stanag 4569 and MIL-A-46100D.

DEVELOPMENT

Especially ballistic safety requirements vary greatly depending on the situation. That is why Kimmelux also develops its products according to individual needs and against different guns and ammunition.

In addition to high quality and careful selection of materials, our experienced workers and command over the whole production guarantee an optimal performance for our products.

OUR RECOMMENDATIONS

At first it would seem that ballistic tests are enough: by shooting at the glass one can see whether the product withstands the bullet. However, the issue is not as simple as that.

Ballistic tests that are in accordance with the standards EN 1063 or Stanag 4569 have to be performed in ideal conditions, which means that the speed of the shot, the distance between shots, the angle of the hit and firing distance are carefully outlined in advance.

Although these circumstances might differ from the ones that the products will face in practice, these kinds of test can always be performed in a similar fashion all over again, in standardized circumstances and whenever necessary. However, real-life threats can come in different weather conditions, from different shooting angles and distances, and a more powerful bullet and charge can be used in a gun of the same caliber that the product has been designed to withstand.

That is why we recommend that bullet resistant glazing is tested not only according to the standards, but also according to individual criterion and needs.

We will help you with these issues and perform the required ballistic tests.

Methods of testing

EN 1063 European Standard:
is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet resistant glass. It is commonly used in conjunction with EN 1522 (Euronorm standard for Bullet Resistance in Windows, Doors, Shutters and Blinds) to form a ballistic classification system by which armored vehicles and structures are tested and rated.

 

STANAG 4569: "Protection Levels for Occupants of Logistic and Light Armored Vehicles". Stanag is a Standardization Agreement that is used in the standardization of NATO’s technical standards and procedures in order to improve cooperation between the member nations’ defence and military forces.

Each NATO state ratifies a Stanag and implements it within their own military.

 

TESTING

In the ballistic tests that are in accordance with the European standard (EN 1063) and NATO’s Stanag 4569, the glass is shot three times.

In the centre of the tested item, the hits form an isosceles triangle, the sides of which are 12 cm long.

The test is considered successful when a shot does not penetrate the glass.

 

CLASSIFICATION

EN 1063 is further divided into two classes.

A glass that withstands a bullet without any spalling belongs to class NS.

A glass that withstands a bullet but can spall and splinter from the back belongs to class S.
