Results and discussion

Flash point
Flash point:
372 °C
Atm. press.:
960 hPa

Applicant's summary and conclusion

Conclusions:
Flash point of solvent violet 43 was found to be 372 degC at 960 hPa by open cup method.
Executive summary:

Flash point of solvent violet 43 was determined to be 372°C at room temperature of 30°C and normal atmospheric pressure of 960 hPa. This value when converted into flash point at 101 325 Pa works out to be 392.63 °C. The value indicate to be much higher than the calssification values and so will not be considered as flammable as well.
