Applicant's summary and conclusion

Conclusions:
The test material has been determined to decompose from 452 +/- 0.5 K at 100.96 to 102.25 kPa. As the test material decomposed, no value for the boiling point could be determined. A calculated value of boiling temperature gave a result of greater than 633 K.
Executive summary:

The test material has been determined to decompose from 452 +/- 0.5 K at 100.96 to 102.25 kPa. As the test material decomposed, no value for the boiling point could be determined. A calculated value of boiling temperature gave a result of greater than 633 K.
