Array ( [name] => DIN4102 [title] => DIN 4102 - Testing Flammability and Combustibility of Passive Fire Protection [content] =>
Closely related to BS 476, DIN 4102 is a German standard for the testing of passive fire protection systems, or their component materials, for the degree of flammability and combustibility. The results of testing that complies with DIN 4102 are split into 5 categories: B3 to B1 followed by A2 and A1, with B3 being the most flammable and A1 being the least.
Rating | Degree of Combustibility |
---|---|
A1 | 100% noncombustible |
A2 | ~98% noncombustible |
B1 | Difficult to ignite |
B2 | Normal combustibility (wood) |
B3 | Easily ignited |
