- Relative self-ignition temperature:
- 110 °C
- Remarks on result:
- other: atmospheric pressure (concluded to 1013 hPa)
Applicant's summary and conclusion
- Conclusions:
- According to the guideline VDl 2263, sheet 1 (Grewer-Oven) a self-ignition was observed at 110 °C.
Due to these results further tests are necessary for the classification of the test item according to the
UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria rev. 5)
and to the GHS Regulations and Regulation (EC) 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
