- Executive summary:
A study was conducted to determine the flammability of the substance according to the UN Test Method N.1 as described in the UN Recommendations of Dangerous Goods, Manual of Tests and Criterian part III, sub-section 33.2.1.4. The test substance was formed into a particle train. A hot flame from a gas burner with a diameter of about 6 mm was used to ignite the pile at one end. In the preliminary screening test, the substance was ignited by a hot flame from a gas burner. The flame extinguished shortly after the gas burner was removed without propagating along the particle train. Under the study conditions, the substance was not classified as a readily combustible solid (Kintrup, 2016).
Reference
The test substance was formed into a particle train. A hot flame from a gas burner with a diameter of about 6 mm was used to ignite the pile at one end. In the preliminary screening test, the substance was ignited by a hot flame from a gas burner. The flame extinguished shortly after the gas burner was removed without propagating along the test train. The test substance was not classified as a readily combustible solid of the UN Class 4.1.
The classification, based on the test results of the self-heating substances, is to be made according to the Regulation (EC) 1272/2008 of the European Parliament and of the Council on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH).
Description of key information
The flammability was determined according to the UN Test Method N.1 (Kintrup, 2016).
Key value for chemical safety assessment

Justification for classification or non-classification
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.
