DIN Categorisation of building materials
Materials can be tested for the degree of flammability and combustibility in accordance with DIN 4102. The following are the categories in order of degree of combustibility as well as flammability:
A1 100% noncombustible = nichtbrennbar
A2 ~98% noncombustible = nichtbrennbar
B1 difficult to ignite = schwer entflammbar
B2 normal combustibility (like wood)
B3 easily ignited = leichtentflammbar |
