- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: UN no. ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8 and Class 9, Paragraph 32.4.1, 2009
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Version / remarks:
- 2002
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: ASTM International, ASTM D 93: “Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester”, December 10, 2002
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- non-equilibrium method closed cup
- Key result
- Remarks on result:
- no flash point - measurement carried out until boiling temperature
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The Pensky-Martens closed cup method was applied for the determination of the flash-point of an aqueous solution of the substance, according to UN, EC, ISO and ASTM guidelines and according to GLP principles. As no flash-point was observed up to boiling of the test substance, it can be concluded that aqueous solutions of the substance have no flash-point.
Reference
It was visually observed that the test substance started to boil at a temperature of approximately 94°C. No flammable vapour/air mixture was produced at temperatures up to boiling of the test substance. From this, it was concluded that the test substance has no flash-point.
Description of key information
Aqueous solutions of the substance have no flash-point
Key value for chemical safety assessment
Additional information
The Pensky-Martens closed cup method was applied for the determination of the flash-point of an aqueous solution of the substance, according to UN, EC, ISO and ASTM guidelines and according to GLP principles. No flash-point was observed up to boiling of the test substance.
