Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The test substance was tested for flammability potential according to the internationally accepted EU method A.10.
The melting of the specimen around of the flame contact area was observed. Flames or other phenomena are not observed on the surface of the molten product. After the removing of the ignition source there is no propagation of combustion, but only the generation of grey smoke. The sample is not highly flammable as no propagation was observed in the preliminary screening test.
Justification for classification or non-classification
According to CLP Regulation (EC) No. 1272/2008, 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
In many cases, a simple screening test (see Section 2.7.4.4) can be used to determine whether a solid should be classified as flammable.
Flames or other phenomena are not observed on the surface of the molten product. After removal of the ignition source there is no propagation of combustion, but only the generation of grey smoke.The sample is not highly flammable because no propagation is observed in the preliminary screening test.
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.
