BS EN 1063

Ballistic Glass

The European standard for ballistic glass is BS EN 1063. It rates glass based on its ability to stop different weapons and ammunition. The classification spans nine levels, from BR1 (lowest) to BR7 (highest), plus two specific levels for shotguns (SG1 and SG2).

The standard

How the glass is tested

The European standard for ballistic glass is BS EN 1063. It rates glass based on its ability to stop different weapons and ammunition. The classification spans nine levels, from BR1 (lowest) to BR7 (highest), plus two specific levels for shotguns (SG1 and SG2).

To pass the test, three controlled shots are fired into a 120 mm triangle pattern, and the bullet must not penetrate the glass safe side.

BR1 to BR7

Standard protection levels

BS EN 1063 rates glass by the weapon and ammunition it stops. BR1 is the lowest level and BR7 the highest, with SG1 and SG2 covering shotguns. Each level is passed only if three shots in a 120 mm triangle fail to penetrate the safe side.
Level
BR1 to BR7, from lowest to highest protection. BR2 to BR4 are tested against handgun rounds; BR5 to BR7 against rifle rounds.
Weapon and round
The type of weapon and the specific ammunition each level is tested against, as defined under BS EN 1063.

S vs NS

The spall categories

During testing, the glass is also rated by whether it splinters on the safe side.
S Spall Allowed
The bullet is stopped, but flying glass fragments (splinters) penetrate the safe side.
NS No Spall
The bullet is stopped, and the safe side remains smooth with no dangerous glass splinters.

Applications

Where ballistic glass is used

The client documents do not list applications for ballistic glass. The uses, descriptions and images below are the designer's suggestions to show the layout, and await the client's confirmation and photographs.

  • Banks & cash handling

    Counter screens and teller positions where staff face the public.

  • Police & custody suites

    Front desks, interview rooms and custody areas needing a rated barrier.

  • Embassies & government

    Entrances and reception glazing for buildings with an elevated threat level.

  • Gatehouses & guard posts

    Glazed guard positions at site entrances and perimeter checkpoints.

  • Jewellers & high-value retail

    Shopfronts and display cases that resist attack without hiding the goods.

  • Reception & interview screens

    Discreet protection for staff in public-facing offices and clinics.

  • Control rooms

    Secure observation glazing for security, utilities and transport control rooms.

  • Fuel stations & kiosks

Construction

Glass construction

The glass is assembled using multi-layers of glass and polycarbonate, with PVB interlayers.

For NS glass a final thin layer is added to the safe side.
