Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (EDTMP-xCaNa): non-flammable
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The substances are involatile and (are demonstrated or expected to) undergo thermal decomposition.
The requirement to test the substance for pyrophoricity and flammability in contact with water was waived in accordance with Section 1 of REACH Annex IX, because there is no indication on the basis of structure and experience in use and handling that the substance is pyrophoric (flammable in contact with air) or flammable in contact with water.
The burning behaviour of the test item using test method VDI 2263, Part 1, indicated that the substance will produce a flame in contact with ignition source. However, the flame will not propagate along the material and on removal of the ignition source, the flame self-extinguishes. Similarly, a 5 mm layer ignition temperature study by the same author (Rowe 2002, report number 18602) showed that no ignition was observed for the substance using IEC 61241 -2 -1, 1994, Method A and in compliance with GLP. Therefore, it can be concluded that EDTMP-xCaNa is a non-flammable solid. Also, available data for commercial samples indicate the substance not to be flammable and a minimum ignition energuy of >10000 mJ was also reported.
Justification for classification or non-classification
The substance is not classified for flammability as no ignition was observed during the study conducted in accordance to Test Method VDI 2263, Part 1.
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.
