Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Flammability (solids): The test item could not be ignited with a flame in the preliminary test. The performance of the main test was not necessary.
The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10. Due to these results the test item does not have to be classified as "flammable solid", class 4.1 of the Recommendations on the Transport of Dangerous Goods/Manual of Tests and Criteria and according to chapter 2. 7 of the GHS (CLP) regulations.
Flammability (contact with water): The chemical structure of cesium carbonate does not contain any chemical groups, capable of causing the development of a dangerous amount of (flammable) gas (e.g. hydrogen), when in contact with damp air or water. In addition, from experience in handling and use no flammability in contact in water is expected. Therefore, the test substance is considered non flammable in contact with water.
Flammability (pyrophoric properties): From the structural formula of cesium carbonate it can be concluded that the test substance is not pyrophoric. Cesium carbonate does not contain any chemical group that might lead to spontaneous ignition shortly after coming into contact with air at room temperature. In addition, from experience in handling and use no ignition in contact with air is expected.

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.
