Particle size distribution (Granulometry)

Administrative data

Endpoint:

particle size distribution (granulometry)

Data waiving:

Key result

Melting / freezing pt.:

-61 °C

Test was done at ambient atmospheric pressure (value not stated). Stable temperatures were observed around the freezing point. A clear phase transition was observed at temperatures of (-56.9) °C (test 1), (-61.2) °C (test 2), and (-61.0) °C (test 3). The average of two repeatable temperatures was reported as the freezing point.

Table, Measured temperatures around the freezing process.

Temp during test 1 (°C)	Temp during test 2 (°C)	Temp during test 3 (°C)
(-54.5)	(-61.0)	(-60.0)
(-54.9)	(-60.9)	(-60.3)
(-55.3)	(-61.1)	(-60.4)
(-55.6)	(-61.0)	(-60.6)
(-56.1)	(-61.2)	(-60.8)
	(-61.2)	(-60.9)

Conclusions:

The freezing point of HFE s-601 is (-61.0) °C (OECD 102)

Executive summary:

The freezing point range of HFE s-601 was determined by placing the test material in an acetone/dry ice bath with temperature probe readings. The study was conducted in accordance with the OECD 102 method and was GLP compliant; therefore the study is considered reliable without restrictions.
