GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:

Flash point apparatus:
other: Rapid Tester Model RT-1
Specific details on test material used for the study:
Physical state: clear solid
Key result
Flash point:
100.5 °C
Atm. press.:
760 mm Hg

The test material ignited at 100 °C but did not ignite at 99 °C at 747.8 mm Hg. The flash point was corrected to a pressure of 760 mm Hg using the formula:

FP = T + 0.03(760-P)

T = Observed flash point temperature (°C)

P = Barometric pressure (mm Hg)

The corrected temperature is rounded to the nearest 0.5 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of 1,1'-isophthaloylbis(2-methylaziridine) was 100.5 °C under atmospheric conditions (760 mm Hg) according to ASTM D3828.
Executive summary:

The flash point of 1,1'-isophthaloylbis(2-methylaziridine) was tested using a closed-cup method. The flash point was determined with temperature steps of 1 °C. The test material ignited at 100 °C but did not ignite at 99 °C at 747.8 mm Hg. The lowest flash point corrected to 760 mm Hg was rounded down to the nearest 0.5 °C, and was determined at 100.5 °C. The study was conducted in accordance with ASTM D3828 and under ISO170255; therefore the study is considered reliable without restrictions.
