Discussion and Conclusion
The determination of the flash point of the test item was performed according to EC method A.9 and ISO 2719:2016. The flash point was determined at a temperature of 182.5 °C.
Since the flash point was > 60 °C, the test item should be classified as not flammable.
Applicant's summary and conclusion
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.
