Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
October 1992 - January 1993
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Principles of method if other than guideline:
The following was measured:
- flash point (closed): according to BS6664 part 5 (Pensky-Martens closed cup)
- flash point (open) and fire point: according to BS2000 (Pensky-Martens open tester)
GLP compliance:
yes
Type of method:
equilibrium method closed cup
Key result
Flash point:
> 360 °C
Atm. press.:
1 028 hPa
Remarks on result:
other: closed cup
Flash point:
255 - 258 °C
Atm. press.:
1 028 hPa
Remarks on result:
other: open cup; mean: 257 °C
Flash point:
283 - 284 °C
Atm. press.:
1 028 hPa
Remarks on result:
other: fire point; mean: 284 °C

The certified flash point reference material n-hexadecane was determined as:

      T/° C
 Observed flash point (C) 132   135
 Pressure corrected flash point 131.6   134.6
 Mean flash point  133.1   

The recorded closed flash point of n-hexadecane : 133.5 °C. Repeatability required (± 5 °C) : requirement satisfied Reproducibility required (± 8.5 °C) : requirement satisfied Corrected flash point = C + 0.033 (760-P) where: C = observed flash point, ° C P = ambient barometric pressure, mm Hg Barometric pressure (P) at time of standards test = 771.1 mm Hg (1028 hPa) Correction to flash point = + 0.4 °C for thermometer

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of 1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined at >360 °C c.c. at 1028 hPa.
Executive summary:

The flash point of 1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined according EU method A.9 (Pensky-Martens, closed cup). The flash point was measured in closed cup at >360 °C by 1028 hPa.
