Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
not determinable

Any other information on results incl. tables

When tested according to a company guideline, local burning without spread was noticed and the test substance was assigned to combustion class 3: "local burning or glowing without spread" (definition according to HVBG, 2011)

As the flame does not propagate, no burning rate can be determined. Reference: HVBG, Hauptverband der gewerblichen Berufsgenossenschaften: GESTIS-DUST-EX Database - combustion and explosve characteristics of dusts, Edition 2/2001 HVBG, Sankt Augustin, 2001
