Key result
Test procedure:
burning rate test: preliminary screening test
Moisture (wt %):
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

In the preliminary test the test item could not be ignited. Based on the results of the preliminary test, no main test was performed.

Interpretation of results:
GHS criteria not met
In the preliminary test, the sample discoloured to black. A small orange flame was produced which did not spread. Localised glowing was observed. Therefore no further testing is required.
Executive summary:

The purpose of this test was to determine the burning rate of the test material as received. The substance was filled into a fire train mould 250 mm long with a triangular cross section of height 10 mm and width 20 mm. After tapping the mould, to settle down the powder, it was inverted onto an impervious non-combustible plate of low thermal conductivity and the mould was removed. An ignition source (Micro-torch flame) was placed at one end of the pile for 2 minutes. In the preliminary test, the substance turned black. A small orange flame was produced which did not spread. A full test had therefore not to be carried out. The substance is not classified as highly flammable.
