Description of key information
Multi-Walled Carbon Nanotubes (MWCNT) is classified as not highly flammable when tested according to EU Method A 10 (Heitkamp, 2007).
MWCNT is a type of synthetic graphite which is known not to react with water or damp air. In a test according to EU Method A 12 MWCNT did not liberate gases in hazardous amounts (Heitkamp, 2007).
MWCNT is a type of synthetic graphite which is known not to have pyrophoric properties. In a test according to EU Method A 13 MWCNT did not show any pyrophoric properties (Heitkamp, 2007).
In a test according to VDI 2263, Part 1 (Burning behaviour), the combustibility of MWCNT as rated on a scale from 1 to 6 depending on the course of the reaction (BN = Burning number) showed at room temperature (dried and not dried) and 100°C a BN of 2 (brief ignition and rapid extinction) (Heinz, 2006).
Test material is meeting the form as described in section 4.5 of the IUCLID dossier.

Additional information
Justification for classification or non-classification
Multi-Walled Carbon Nanotubes are classified as not highly flammable when tested according to EU Method A 10.
Multi-Walled Carbon Nanotubes is a type of synthetic graphite which is known not to react with water or damp air (EU Method A 12) and is known not to have pyrophoric properties (EU Method A 13).
According to VDI 2263, Part 1 (Burning behaviour), Multi-Walled Carbon Nanotubes show a brief ignition and rapid extinction (Burning number: 2).
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.
