Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 flammability of the substance was evaluated according to the EU Method A.10 and UN Method N1. In the preliminary study the test substance was heated with the flame of a gas burner for two minutes. No ignition was observed and thus no combustion along 200 mm could be measured.
Since ignition did not occur within two minutes, the test substance is not considered as highly flammable (for EU regulations) and not classified as flammable solid (for UN regulations), resp. The test substance carbonized light (only a few parts were black). No sign of ignition within two minutes.
No determination of burning rate was necessary.
Justification for classification or non-classification
According to the CLP Regulation (EC) No. 1272/2008: A flammable solid means a solid which is readily combustible, or may cause or contribute to fire through friction. Readily combustible solids are powdered, granular, or pasty substances or mixtures which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly. The classification criteria for flammable solids are indicated in the CLP Regulation as follows:
Annex I: 2.7.2.1. Powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys – see 2.7.2.2) 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 RTDG, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2,2 mm/s. 2.7.2.2. Powders of metals or metal alloys shall be classified as flammable solids when they can be ignited and the reaction spreads over the whole length of the sample in 10 minutes or less. 2.7.2.3. A flammable solid shall be classified in one of the two categories for this class using Method N.1 as described in 33.2.1 of the UN RTDG, Manual of Tests and Criteria in accordance with Table 2.7.1.
During the preliminary test the test substance carbonized light (only a few parts were black). No sign of ignition within two minutes.
No burning rate was therefore determined and the substance is not classified as flammable according to the CLP Regulation.
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.
