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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Remarks:
- Burning distance: 17 mm
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 120 s
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Remarks:
- Burning distance: 21 mm
- Interpretation of results:
- not classified based on GHS criteria
Reference
As the test item does not propagate combustion by burning with flame along 200 mm of the powder train within the 2 minutes test period, it can be considered as "Not readily combustible solid of Division 4.1".
Description of key information
non flammable
no pyrophoricity
no flammability on contact with water
not self-heating
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
No propagation of combustion by burning with flame along 200 mm of the powder train within the 2 minutes test period in a preliminary screening test according to UN MTC Test N.1.
Based on experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.
The substance is completely molten at 160 °C, therefore it can be considered as not self-heating.
Justification for classification or non-classification
The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:
No propagation of combustion by burning with flame along 200 mm of the powder train within the 2 minutes test period in a preliminary screening test according to UN MTC Test N.1.
Based on experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.
The substance is completely molten at 160 °C, therefore it can be considered as not self-heating.
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.
