Preliminary test

No congealing was observed down to a temperature of -50.0 °C.

 

Main test

As no congealing was observed in the preliminary test, no further tests were performed.

Conclusions:
No freezing point of the test item could be determined down to a temperature of -50 °C.
Executive summary:

A study was conducted according to OECD TG 102, Regulation (EC) No 440/2008 method A.1 and EPA OPPTS test guideline 830.7200 to determine the freezing point of the test item using crystallizing apparatus. Therefore, in a preliminary test the crystallizing apparatus was filled to the third with the test substance, the thermometer sensor was introduced and was used to gently stir the content continuously. The crystallizing apparatus was slowly cooled in the cold bath and the test substance was observed while reading the temperature. No solidification was observed down to a temperature of -50 °C. Thus, no main test was performed. The freezing point of the test item was determined to be below -50 °C at 1013.25 hPa. No observations were made which cause doubt on the validity of the outcome of the study.

Description of key information

The test item has no melting point down to a temperature of -50 °C at 1013.25 hPa. In accordance with column 2 Annex VII section 7.2 of Regulation (EC) No 1907/2006 (REACH), no further test on melting point need to be conducted as the melting point of the substance is below -20°C.

Key value for chemical safety assessment

Additional information

A study was conducted according to OECD test guideline 102 to determine the freezing point of the test item using crystallizing apparatus. In a preliminary test no solidification was observed down to a temperature of -50 °C. Thus no main test was performed. The freezing point of the test item was determined to be below -50 °C at 1013.25 hPa.

In accordance with column 2 Annex VII section 7.2 of Regulation (EC) No 1907/2006 (REACH), no further test on melting point need to be conducted as the melting point of the substance is below -20°C.
