Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
not highly flammable
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The flammability of the substance was evaluated according to the EU Method A.10 (Flammability (Solids).
The substance is not considered highly flammable.
Justification for classification or non-classification
According to Regulation CLP 1272/2008, Annex I, section 2.7.1.1, 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 4 seconds or the rate of burning is more than 2,2 mm/s.
Criteria for flammable solids are:
Category 1: Burning rate test
Substances and mixtures other than metal powders:
(a) wetted zone does not stop fire and
(b) burning time < 45 seconds or burning rate > 2,2 mm/s
Category 2: Burning rate test
Substances and mixtures other than metal powders:
(a) wetted zone stops the fire for at least 4 minutes and
(b) burning time < 45 seconds or burning rate > 2,2 mm/s
The flammability of the substance was evaluated according to the EU Method A.10 (Flammability (Solids).
In a preliminary test (40 mm pile) a smouldering fire was observed. Therefore a main test was performed, assessing before the moisture content (5.1 % by drying).
In the main test a smouldering fire, throughout the whole mass was observed, but the substance is not considered highly flammable. The burning time was in the range of 335 -390 seconds for 100 mm, therefore the substance is not classified as flammable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
