Results and discussion
Auto-ignition temperature (liquids / gases)
- Remarks on result:
- other: From the experiences with five cesium salts it can be assumed that cesium hydrogen carbonate is not auto-flammable.
Relative self-ignition temperature (solids)
- Remarks on result:
- other: From the experiences with five cesium salts it can be assumed that cesium hydrogen carbonate is not auto-flammable.
Applicant's summary and conclusion
- Conclusions:
- From the experiences with five cesium salts it can be assumed that cesium hydrogen carbonate is not auto-flammable.
- Executive summary:
“For the determination of the auto-ignition temperature read-across is usually not possible.However interpolation may still be possible within homologous series.” [ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7a: Endpoint specific guidance, Version 3.0, August 2014]
Even if different cesium salts do not fit in the concept of homologous series, there are values for results cesium salts according to EU A.16 available.
Cesium iodide not auto-flammable
Cesium hydroxide *H2O not auto-flammable
Cesium sulphate not auto-flammable
Cesium nitrate not auto-flammable
Cesium chloride not auto-flammable
From the experiences with five cesium salts it can be assumed that cesium hydrogen carbonate is not auto-flammable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
