flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

26 Mar 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: ASTM D3828, Standard Test Methods for Flash Point of Liquids by Small Scale Closed Cup Tester.

Deviations:

no

GLP compliance:

no

Other quality assurance:

ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)

Type of method:

closed cup

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.
