BUILDING MATERIAL CLASSES

Fire class

In Germany, the fire class of fabrics and projection screens is determined in accordance with DIN 4102 Part 1-4. This standard is also used as a basis in many other European countries. Basically, this DIN regulates tests and requirements for the fire behavior of building materials and components. The test procedure is described in detail in DIN 4102-1.

Other countries have their own fire protection standards, e.g. the NF P 92- 503 M1 / M2 standard applies in France, the British Standard BS 5867 2B in England and the NFPA 701 standard in the USA. In Europe, fire classification has now been standardized in most countries with EN 13501-1, although the national standards often still apply in parallel to the European standards. In Germany, too, the classification according to DIN 4102-1 is still much better known than that according to EN 13501-1.

Today's very strict fire protection standards on the use of flame-retardant materials in theaters and event areas are also due to the catastrophic fire at the Vienna Ringtheater in 1881, in which 385 visitors perished in the flames.

International safety with the fire class of projection films

In the field of PVC projection films, additives are added to the plastic to create the conditions for flame retardancy. This means that the projection films comply with the fire classes specified in the state building regulations. In Germany, DIN 4102 Part 1-4 and the European fire class certification EN 13501-1 still apply in parallel. Anyone who operates internationally and serves customers all over the world must not only comply with the German fire protection guidelines, but also ensure that the projection films also comply with the fire protection regulations abroad as far as possible. Gerriets projection screens also comply with other international fire protection standards, such as the American standard NFPA 701. In Europe, as mentioned above, the fire classification is now standardized in most countries with EN 13501 Part 1. Nevertheless, the national standards often still apply in parallel to the European standards. In Germany, classification according to DIN 4102-1 is often even better known than according to EN 13501.
