GMW 17920 Heated Laminated Glass Standard

EUROLAB Laboratory provides accredited testing and conformity assessment services within the scope of the GMW 1790 standard. This specification contains standards for the manufacture and use of laminated glass, which reduces the risk of injury by holding glass fragments in place as a result of breakage in vehicles.

Laminated glass facilitates vehicle windshield crack repair thanks to its structural formation. However, its use is quite common, as it reduces the risk of injury in accident situations if the damage is beyond repair.

The reasons for the preference of laminated glass; high strength, resistance to fragmentation, sound insulation, security.

High Power:

Unlike regular glass, laminated glass consists of two sheets of glass with a polyvinyl butyral interlayer between them. This thickness, together with the interlayer material, creates the strength of the glass. The strong plastic interlayer has high tensile strength and rigidity. All this means that it will take a lot of force to break the windshield of laminated glass, unlike traditional single-pane glass.

Resistance to Fragmentation:

Laminated glass also shows high resistance to breakage. Where many standard windshields crack under normal to above-normal pressure, laminated glass can remain intact. The interlayer uses compression forces to hold broken glass fragments in place.

Sound insulation:

Laminated glass acts as a strong barrier against external noise. Most of the sound waves that pass through laminated glass are absorbed by the two layers of glass pane and interlayer.

Security:

Laminated glass also protects occupants from bullets that can come from stone particles thrown from the road or passing by a grain of sand. The high strength and explosion resistance of laminated glass against bullets provides much more safety to passengers.
