- Melting / freezing pt.:
- 280 K
- Remarks on result:
- other: Pour Point
- Conclusions:
- The pour point of the test material has been determined to be 280±3 K
- Executive summary:
The pour point was determined using BS 2000: Part 15 (equivalent to ISO 3016), Method 102 of the OECD Guidelines.
A sample of test material was poured into a test jar which was then enclosed in a glass jacket. The sample was heated to 46ºC in a water bath set at 48ºC before being allowed to cool in air to 35ºC. The sample was tranferred to a bath maintained at -1ºC to 2ºC and cooled to 10ºC, then transferred to a bath maintained at -18ºC to -15ºC. Starting at 16ºC and at intervals of 3ºC, the sample was tilted to a horizontal position for a period of 5 seconds, during which the sample was observed for signs of flow.
The pour point of the test material has been determined to be 280±3 K.

- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 01/2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM 57C
- Deviations:
- no
- GLP compliance:
- no
- Melting / freezing pt.:
- > 5 - < 10 °C
- Conclusions:
- The freezing point is 5-10ºC ± 0.5ºC
- Executive summary:
The test material was performed according to the method ASTM 57C. The freezing point is 10 -5 ºC ± 0.5ºC.
