Test

Melting- / Freezing temperature

1

< –100 °C

2

< –100 °C

 

Mean value:

< –100 °C,<173 K

Approximate accuracy of the instrument: ± 0.5 K (up to 600K)

Conclusions:
A melting point value of <-100°C was determined for the substance in accordance with a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.

Description of key information

Melting point: <-100°C at 1013 hPa (EU Method A.1)

Key value for chemical safety assessment

Additional information

A measured melting temperature of <-100°C at 1013 hPa was determined for the submission substance using Differential Scanning Calorimetry (DSC) in accordance with EU Test Method A.1 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.
