Justification for type of information:
For justification of read-across see endpoint summary
Reason / purpose:
read-across source
Key result
Remarks on result:
other: The test item has been determined not to have a relative self-ignition temperature below its melting temperature.
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Between 21 June 2012 and 02 October 2012.
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions, however no formal claim of GLP compliance was made.
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
no
Key result
Remarks on result:
other: 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 crystalline 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, the cube was empty and the base of the cube holder was partly covered with a brown viscous liquid which solidified on cooling.

Please see Attachment 1 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 (HMDTMP-xK): No relative self-ignition observed below the melting / decomposition temperature

Key value for chemical safety assessment

Additional information

No relative self-ignition observed below the melting / decomposition temperature in a reliable test conducted in accordance with the appropriate guideline.
