GMW 15959 Blackout Coating (Frit) Standard for Automotive Glass

EUROLAB Laboratory provides accredited testing and conformity assessment services within the scope of GMW 15959 standard. This standard describes GM requirements for the manufacture and manufacturing process of frit glass coatings used to protect vehicle occupants from ultraviolet rays.

Frit itself is a ceramic component that can be placed in a series of patterns, most typically of dots or lines. These patterns can then be screen-printed onto annealed glass using frit paint.

Frits were originally developed to provide an insoluble flow source for low to medium range glazes or to allow the formulation of faster melting glaze recipes. Each frit has a certain flow element ratio to each other and to alumina when used, as well as to boron.

Fritty frit tubes are small pieces of differently colored glass introduced during the heating process and used to line the inside of a clear glass tube. Glass artists can create an ombre effect by using different colors and fading them together.

Frit glass is fine-pored glass through which gas or liquid can pass. It is made by digesting glass particles in a solid but porous body.

As Eurolab laboratory, it provides the best service to you, our manufacturers, with its experienced and professional staff within the scope of all automotive standards.
