- Type of method:
- closed cup
- Flash point:
- 157 - 159 °C
- Atm. press.:
- 1 005 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point in closed cup is 158°C.
- Executive summary:
In a study (CRTL, 2009), the flash point of 4 -tert-butylcatechol was determined according to the regulation (EC) n°440/2008, A.9.
The cup of the apparatus was filled with the sample. The heat was supplied at a constant rate 5 to 6°C/min with stirring at 120 rpm.
The tests were performed with a temperature ramp beginning at a predetermined temperature.
The determined flash point (closed cup) was 158°C at 1005 hPa.
This study is classified as acceptable and satisfies the guideline requirements for a flash point study.

Additional information
One experimental study (CRTL, 2009) with reliability 1 according to Klimisch was available and was selected as key study. Flash point was determined according to the regulation (EC) n°440/2008, A.9.
The cup of the apparatus was filled with the sample. The heat was supplied at a constant rate 5 to 6°C/min with stirring at 120 rpm.
The tests were performed with a temperature ramp beginning at a predetermined temperature.
The determined flash point (closed cup) was 158°C at 1005 hPa.
