- Conclusions:
- The melting/freezing temperature of the test material has been determined to be greater than 400 °C.
- Executive summary:
The test material appeared as a white solid on completion of testing (i.e. as initial appearance) indicating no physical change had occurred.
The melting/freezing temperature of the test material has been determined to be greater than 400 °C.
The temperature accuracy of the DSC was assessed using an indium reference standard (purity*99.99998%). The melting temperature was determined to be 156.5 °C and within the defined tolerance (156.6 +- 5 °C). The DSC was therefore considered acceptable for use.
