Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Relative self-ignition temperature:
- > 360 °C
- Remarks on result:
- no self ignition observed under the test conditions
Any other information on results incl. tables
At the highest tested temperature (360°C) there was no reaction observed for deposited MDI-Urone dust.
Applicant's summary and conclusion
- Conclusions:
- No auto-ignition of deposited MDI-Urone dust occurred on surfaces until 360°C.
- Executive summary:
The test determines the ignition temperature of a deposited dusty test substance on hot surfaces. The test is conducted according to the test protocol. The surface area of the substance is increased intentionally in this test by preparing the test substance accordingly to simulate the deposited dusty properties. The ignition temperature of deposited dusty test material is expected to be lower than the ignition temperature of the solid with larger particle diameters. At the hottest temperature in this test (360°C) there was no reaction observed for deposited MDI-Urone dust.
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.
