Remarks:
inspected: November 2011; signature: March 2012
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
< -20.15 °C
Atm. press.:
1 atm
Remarks on result:
other: mean result of two determinations; < -20.15 ±0.5 °C or < 253 ±0.5 K
Conclusions:
The freezing temperature of the substance has been determined to be less than 253 ± 0.5 K or < -20.15 ± 0.5 °C.
Executive summary:

The melting/freezing temperature was determined using EU Method A.1 and OECD TG 102 - crystallisation point / freezing temperature method under GLP. The mean freezing temperature of the test substance has been determined to be less than 253 ± 0.5 K or < -20.15 ± 0.5 °C at 1 atmosphere pressure.

Description of key information

Fp: < 253 K (< -20.15 °C) at 1 atm, EU Method A.1 - crystallisation point / freezing temperature method, 2013

Key value for chemical safety assessment
