Results and discussion

Flash point
Key result
Flash point:
<= 10 °C
Atm. press.:
101.3 kPa

Any other information on results incl. tables

8.1 If the barometric pressure reading is measured in a unit other than kilopascals, convert to kilopascals.

8.2 Correction of observed flash point to standard atmospheric pressure

Calculate the corrected flash point,Tc, using following formula:

Tc =Td + 0.25×(101.3-p)

Where

Td is the detected flash point , expressed in °C;

P is the absolute barometric pressure, expressed in kPa;

0.25 is a constant, expressed inoC/kPa;

101.3 is used as the standard atmospheric pressure, expressed in kPa.

8.3 Report the flash point, corrected to standard atmospheric pressure, rounded to the nearest 0.5oC.

According to the measurement data, the sample is cooled to 10in the refrigerator, and the samples are taken into the sample tank, and the sample can be ignited without heating. So the closed flash point of the sample is less than 10.

Based on the determination results, the flash point of sample isless than 10.

Applicant's summary and conclusion

Interpretation of results:
Category 2 (highly flammable liquids) based on GHS criteria
Conclusions:
Based on the determination results, the flash point of sample is less than 10 °C
