DIN 4102-1 Fire behaviour of building materials and elements Part 1: Classification of building materials Requirements and testing

1 Scope
1.1 This standard defines fire behaviour classes for building materials and specifies requirements and test methods for each class. It applies to sheet materials (including plates and slabs), composite materials, material
assemblies, coverings, insulation, coatings, pipes and fittings, decorative materials, curtains and other materials suspended from ceilings, fire retardants, and intumescent coatings, whether or not these materials are
designated as construction products (‘Bauprodukte’) in the German Länder building regulations (cf. Explanatory notes).

1.2 The classification specified in this standard serves to assess the fire behaviour of materials alone or in combination. Fire behaviour not only depends on the nature of the material, but also on its shape, surface
characteristics, density, processing, and its combination with other materials, including any bonding agents or fasteners used. These factors are to be taken into account when preparing tests, selecting specimens, evaluating
test results and marking the materials.
