The labs of GWP offer testing services for the measurement of the fire resistance of samples and components. The fire resistance is a measure for the time during which functionality is maintained. In combination with further criteria it forms the basis for the rating according to fire resistance classes. The fire resistance classes refer to the fire characteristics of the whole product and must not be mixed up with the rating of the single building products or materials (i.e. “Baustoffklassen” according to DIN 4102-2).
