Endpoint:
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
Reference:
Composition 0
Qualifier:
according to
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
Test material information:
Composition 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.

Endpoint:

Type of information:
not specified
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
documentation insufficient for assessment
Reference:
Composition 0
Qualifier:
no guideline followed
Principles of method if other than guideline:
Closed cup
GLP compliance:
no
Type of method:
closed cup
Test material information:
Composition 1
Key result
Flash point:
>= 200 °F
Interpretation of results:
study cannot be used for classification
Conclusions:
A flash point of ≥ 200 °F using a closed cup method was reported for 1,1'-isophthaloylbis(2-methylaziridine).
Executive summary:

A flash point of ≥ 200 °F using a closed cup method was reported for 1,1'-isophthaloylbis(2-methylaziridine). Only the result was reported on the SDS and no details associated with the study were provided; therefore, the reliability of the data is not assignable.

Description of key information

The flash point of 1,1'-isophthaloylbis(2-methylaziridine) was 100.5 °C under atmospheric conditions (760 mm Hg) according to ASTM D3828.

Key value for chemical safety assessment

Additional information

In the key study, 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 ISO17025; therefore the study is considered reliable without restrictions. In a supporting study, a flash point of ≥ 200 °F using a closed cup method was reported for 1,1'-isophthaloylbis(2-methylaziridine). Only the result was reported on the SDS and no details associated with the study were provided; therefore, the reliability of the data is not assignable.
