OTHER SPECIFICS: No - Key result
- Melting / freezing pt.:
- < -25 °C
- Atm. press.:
- ca. 1 013 mBar
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- not determinable
- Remarks:
- The freezing temperature of Test item was determined to be less than -25 °C.
- Conclusions:
- The freezing temperature of Test item was determined to be less than -25 °C.
- Executive summary:
EU Method A.1 (2012) - An aliquot of test item was placed into a test tube contained within a Dewar flask containing a dry ice/acetone mixture. The test item was continuously stirred throughout the test. The temperature and observations of the test item were recorded at periodic intervals. The dry ice/acetone bath was maintained until the sample temperature had reached below -25 °C or until the test item solidified.
In a trial determination, the test item did not solidify as the temperature was decreased from ambient down to -25 °C. No further testing was necessary.
The freezing temperature of the test item was established as being < - 25 ºC.
