METHOD OF TESTING
For German DIN 4102 (B1), a material is classified as B1 if it fulfils the requirements of a B2-test and the ‘fire shaft’ test.
Test method
B1 classification conditions
The residual length is minimum 150mm. The temperature of the smoke is maximum 200°C.
B2 classification conditions
The time to reach the marked point is minimum 20 seconds. The paper doesn’t ignite. The droplets are burning for maximum 2 seconds.
Fire shaft test
A test specimen is hung vertically in a test cabinet with a burner in it. It is subjected simultaneously to a flame for 10 minutes and a constant flow of air from below. The temperature of the smoke and the undamaged length of the specimen are measured.
German DIN 4102 (B1) B2 test
The test specimen is put on a specimen holder that is hung in a test cabinet. A burner flame is applied to it for 15 seconds. The time to reach a marked point is measured. Also the burning droplets are observed by means of a paper placed under the specimen.
Result
The material is classified as:
- B1 Schwerentflammbare Stoffe;
- B2 Normalentflammbare Stoffe;
- B3 Leichtentflammbare Stoffe.
