- Substance type: organic
- Physical state: Solid - Key result
- Flash point:
- > 330 °C
- Atm. press.:
- 970 hPa
- Remarks on result:
- other: The substance did not show flash point upto 330°C
- Conclusions:
- The principle method used to determine the flash point property of the substance is open cup method. According to open cup considerations, test chemical did not show flash point upto 330°C and at atmospheric pressure 970 hPa,hence the flash point of test chemical was considered to be >330 degree C.
- Executive summary:
The principle method used to determine the flash point property of the substance is open cup method. According to open cup considerations, test chemical did not show flash point upto 330°C and at atmospheric pressure 970 hPa,hence the flash point of test chemical was considered to be >330 degree C.
Reference
Since the end point was not attained, it is concluded that this chemical was non flammable.
Description of key information
The principle method used to determine the flash point property of the substance is open cup method. According to open cupconsiderations, test chemical did not show flash point upto 330°C and at atmospheric pressure 970 hPa,hence the flash point of test chemical was considered to be >330 degree C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 330 °C
Additional information
The principle method used to determine the flash point property of the substance is open cup method. According to open cupconsiderations, test chemical did not show flash point upto 330°C and at atmospheric pressure 970 hPa,hence the flash point of test chemical was considered to be >330 degree C.
