Administrative data

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2008-11-07
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The substance was placed at 247 K (-26 °C) for approximately 24 h and was then visually examined. As it was still in a liquid phase, it was concluded that the substance has a melting point below 253 K (-20 °C) and is therefore not applicable according to “Endpoint specific guidance R.7.1.2.1”.
