Principles of method if other than guideline:
Geigy-Kühner Test
An attempt is made to ignite the dust sample heaped to form a strip of product about 2 cm wide and 4 cm lont at one end with a glowing platinum wire with a temperature of about 1000 °C. The wire is immersed only briefly in the dust sample, so that the latter is not heated. A 5 mm to 20 mm thick ceramic plate is used as a base. in the case of melting substances, a modified combustion test is also carried out on a sample to which 20% in weight kieselgur has been added. The result frequently indicates obvious combustion behaviour. The flammability is evaluated by the class numbers BZ 1 to BZ 6 according to the following classification.:
BZ 1 Does not catch fire
BZ 2 Catches fire briefly and extinguishes rapidly
BZ 3 Local burning or glowing without spread
BZ 4 Spread of a glowing fire
BZ 5 Spread of an open fire
BZ 6 Very rapid combustion
GLP compliance:
no
