Test

Melting- /freezing temperature

1

<-100°C

2

<-100°C

 

Mean value

<-100°C, <173 K

During the cooling step the registration of the measurement starts at +25°C with a rate of 5 K/min down to –100°C (blue line) followed by heating from -100°C up to +25°C (red line). The DSC diagrams show no melting/freezing temperature above –100°C. For details see enclosure 1 and 2.

Conclusions:
A melting point value of <-100°C at 1013 hPa 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 a Differential Scanning Calorimetry (DSC) method 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.
