Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
The flammability of the test substance was examined in the burning behaviour test, according to the VDI-guideline 2263.
The test was performed at ambient temperature (20 °C) and at elevated temperature (100 °C) as well. It provides an indication of the extent to which a localised hot spot will propagate throughout a given powder sample, using a combustibility index number: 1 to 6.If the combustibility index of a given sample of powder is 4, 5 or 6 the sample material is further tested under vacuum.
The burning index was 2 at both the temperatures at 20 -100 °C.
Discussion and conclusion
The burning index 2 is assigned to substances for which extinction occurs after short burning (no spreading of fire). A burinig index of 3 is assigned to substances for which local burning or glowing, limited spread of the flame (no spreading of fire) is observed, while a burning index 4 is assigned to substances for which smoldering fire or slow flameless decomposition (fire spreads) is observed. Substances with burning class greater than 4 are candidates for classification as "flammable solids" according to the UN Recommendations on the Transport of Hazardous Goods.
In conclusion, the test item can be considered as non-flammable solid.

- Executive summary:
The test material was examinef for flammable decomposition gases. No flammable decomposition gases were recorded up to 550 ° C.
Conclusion
No flammable decomposition gases up to 550 °C.

Additional information
Burning behaviour test, according to the VDI-guideline 2263, and specific investigation on decomposition gases.
Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, 2.7 Section, Flammable Solids, powdered, granular or pasty substances or mixtures shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.
Alternatively, according to the Guidance on the Application of the CLP Criteria*, the burning index (referred to as ‘class number’ in VDI 2263) as obtained from the Burning Behaviour test (VDI 2263, part 1) may be used. If a burning index of 3 or less is found, the substance should not be classified as a flammable solid and no further testing is required.
A burning index of 2 resulted from the burning behaviour test for the substance.
In conclusion, the substance does not meet the criteria to be classified as flammable, according to the CLP Regulation (EC) No 1272/2008.
