Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.

Description of key information

The key value is taken from a GLP study conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A10
