- Remarks on result:
- other: The test item became slightly cloudy from 281 K but remained non-viscous throughout the investigation.
- Conclusions:
- Freezing temperature of the test material was determined to be less than 253 K (less than minus 20 ºC).
Reference
- Measured temperatures were converted from degrees Centigrade using the equation T = t + 273.15 (where T = temperature (K) and t = temperature (ºC).
Description of key information
Freezing temperature of the test material was determined to be less than 253 K (less than minus 20 ºC).
Key value for chemical safety assessment
Additional information
The freezing temperature of the test item was determined to be less than -20 °C (<253 K) using BS4633: Method for Determination of Crystallizing Point, designed to be compatible with Method A1 Melting/ Freezing Temperature of Commission Regulation (EC) No 440/ 2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
