- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Testing was conducted between 19 May 2011 and 06 August 2011.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:
- according to guideline
- Guideline:
- other: The determination was carried out using the pour point method BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and OECD Method 102
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pour point
- Melting / freezing pt.:
- < 253 K
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No atmospheric pressure was recorded for this endpoint.
- Conclusions:
- The pour point of the test item has been determined to be less than -20°C (<253 K).

Method
The determination was carried out using the pour point method BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Conclusion
The pour point of the test item has been determined to be less than -20°C (<253 K).
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The study was conducted in accordance with internationally recognised guidelines, but was not conducted according to GLP.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- < -50 °C
- Conclusions:
- The melting point of the test item was <-50 °C.
- Executive summary:
The measurement of the liquid test item in open glass crucible showed no endothermic effect (melting) in the temperature range -50 to 180 °C. The melting point is therefore considered to be <-50 °C.

Additional information
The overall endpoint determination was made using pour point method BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The pour point of the test item was determined to be less than -20°C (<253 K).
