Key result
Remarks on result:
no self-ignition observed up to the melting point
Remarks:
The test item has been determined not to have a relative self-ignition temperature below its melting temperature.

    

Results

The test item was a white solid. Whilst heating the test item,no relevant exothermic reaction/self-heating of the sample had been observed.The temperature/time curve is shown below. On completion of the test, a sticky brown viscous liquid was found in the cube, on the cube stand and on the base of the oven.

Please see Attachment 1 of this Summary for Figure 3.3 - Temperature Curve.

Conclusions:
The test item has been determined not to have a relative self-ignition temperature below its melting temperature.
Executive summary:

Testing was conducted using a procedure designed to be compatible with Method A16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.

     

Conclusion

The test item has been determined not to have a relative self-ignition temperature below its melting temperature.

Description of key information

Relative self ignition (EDTMP-H): The substance was observed not to have a relative self-ignition temperature below its melting point (Atwal, 2012).  

Key value for chemical safety assessment

Additional information

The relative self-ignition temperature of EDTMP-H was performed in accordance with EU Test Method A.16 and in compliance with GLP. EDTMP-H was observed not to have a relative self-ignition temperature below its melting point.
