Overall result: Decomposed from approximately 573 K
Discussion
As a result of the low rate of enthalpy change during decomposition, the onset temperature can only be approximated.
Non-similar thermographic profiles were obtained using air and nitrogen atmospheres; this indicates that the observed decomposition in the air determinations is mainly oxidative.
Conclusion
The test material has been determined to decompose from approximately 573 K. As the test material decomposed, no value of melting temperature could be determined.
Applicant's summary and conclusion
- Conclusions:
- The test material has been determined to decompose from approximately 573 K. As the test material decomposed, no value of melting temperature could be determined.
- Executive summary:
The determination for substance CM-5 in project number 0345 -0889 was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A1 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC), Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The test material has been determined to decompose from approximately 573 K. As the test material decomposed, no value of melting temperature could be determined.
