Results and discussion
Auto-ignition temperature (liquids / gases)
- Key result
- Auto-ignition temperature:
- 235 °C
- Atm. press.:
- >= 995.4 - <= 1 008 hPa
Any other information on results incl. tables
The test item ISOPROPYL NITRITE has an auto-ignition temperature of 235 °C according to theRegulation EC No. 440/2008 Method A.15.Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
It is noted here that according to ECHA guidance – Guidance on information requirements and chemical safety assessment; chapter R.7A: Endpoint specific guidance, October 2015 – the auto-ignition temperature for liquids is not used directly for classification and labeling according to regulation (EC) 1272/2008. However, it can be used in the chemical safety assessment in considering risks associated with processing the substance.
According to DIN EN 13463-1 the test item has to be assigned to temperature class T3 (see the followingTable3).
Applicant's summary and conclusion
- Conclusions:
- The test item ISOPROPYL NITRITE has an auto-ignition temperature of 235 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003).
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.
