- Justification for type of information:
- The flash point of 138492 was deThe flash point of 138492 was determined by PMC Test Code 10328- ASTM D93, Pensky-Martens Closed Cup Tester following ASTM D93 Procedure A on July 14, 2017.termined by PMC Test Code 10328- ASTM D93, Pensky-Martens Closed Cup Tester following ASTM D93 Procedure A on July 14, 2017.
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM 5090
- Deviations:
- not applicable
- Principles of method if other than guideline:
- Section 20 of OECD Guideline 102 states ASTM D97, Standard Test Method for Pour Point of Petroleum Products as a suitable melting point determination method for oily substances.
Although ASTM D97, Standard Test Method for Pour Point of Petroleum Products, is referenced in the Appendix of Guideline 102, ASTM D5950 using an automatic apparatus offers better repeatability and reproducibility relative to ASTM D97. Test material 138492 was analyzed by PMC Test Code 10603, Pour Point of Petroleum Products (Automatic Tilt Method) by ASTM D5950 on July 12, 2017. - GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- pour point
- Melting / freezing pt.:
- ca. 8 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- The pour point of 138492 is 281°K (8°C).
- Executive summary:
The pour point of 138492 is 281°K (8°C).
Reference
The sample was heated to approximately 45ºC and then inserted into the automatic pour point apparatus. The sample was cooled according to the cooling profile listed in Table 1 of ASTM D5950 and examined at 1°C intervals. The lowest temperature at which movement of the sample was detected by the automatic equipment was displayed as the pour point.
The pour point of 138492 is 281°K (8°C).
