Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Remarks:
- EC Method A.1, OECD Method 102
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- not applicable
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Principles of method if other than guideline:
- not applicable
- GLP compliance:
- yes
- Other quality assurance:
- other: Council Regulation (EC) No 440/2008 (as amended) of 30 May 2008 and REACH Regulation (EU) No 1907/2006 of the European Parliament and of the Council
- Type of method:
- pour point
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No. of test material: 8515025
- Expiration date of the lot/batch: 23 March 2018
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature (15 - 25 degree Celsius)
FORM AS APPLIED IN THE TEST (if different from that of starting material) -
- Physical state: Viscous liquid (The test item becomes a waxy solid on standing at room temperature for prolonged periods) - Key result
- Melting / freezing pt.:
- 3 °C
- Remarks on result:
- other: The pour point, defined as the lowest temperature at which the test item was observed to flow, was found to be 3°C (mean of 3 degrees C and 3 degrees C).
- Conclusions:
- Under the conditions of the study, the pour point, defined as the lowest temperature at which the test item was observed to flow, was found to be 3°C (mean of 3°C and 3°C).
- Executive summary:
The freezing temperature of the test substance was evaluated according to EC Method A.1, OECD Method 102, under GLP and as the test item was observed to solidify without crystallisation in a preliminary test, a pour point test was considered appropriate and was determined according to ASTM Test Method D97.
Procedure: A cylindrical glass jar was filled to a specified mark with test item, which had been melted at 60°C to liquefy and make homogenous. The jar was sealed using a cork fitted with an ASTM 5C/IP1C high cloud and pour thermometer and then placed in (but insulated from) a metal jacket. The sample was placed in a waterbath maintained at 24°C. At 3°C intervals beginning at 45°C, the jar was removed from the jacket, tilted to check for sample movement and then returned to the jacket, the procedure being performed in 3 seconds. At 27°C, the sample was transferred to an ice/water bath and, at temperatures below 9°C, to an acetone/solid carbon dioxide bath maintained at -18°C. When no initial movement was observed, the jar was held in a horizontal position for 5 seconds to check for sample movement and the procedure was condcuted in duplicate.
Under the conditions of the study, the pour point, defined as the lowest temperature at which the test item was observed to flow, was found to be 3°C (mean of 3°C and 3°C).
