Key result

Flash point:

> 135 °C

Atm. press.:

101.325 kPa

Remarks on result:

other: the test item has no flash point and/or no flammable vapour/air mixture was produced, up to 135°C the temperature at which decomposition occurs. Therefore any flash point must be > 135 °C.

Preliminary Test:

Starting at 25°C, an attempt was made to ignite the vapour of the test item for every 2°C temperature rise. No flash-point was observed below the temperature at which reaction and/or degradation of the test item (i.e. 135°C) occurred. Therefore, the preliminary test was repeated. The temperature of the test item at the start of the additional test was 25°C. Starting at 25°C the ignition source was applied for every 2°C temperature rise.

 

It was visually observed that the test item reacted and/or degraded at approximately 135°C. No flammable vapour/air mixture was produced at temperatures below the temperature at which reaction and/or degradation of the test item occurred. From this, it was concluded that the test item has no flash point. Due to decomposition and/or no flammable vapour/air mixture was produced.

 

Main Study :

Not performed.

Conclusion: the test item has no flash point and/or no flammable vapour/air mixture was produced, up to 135°C the temperature at which decomposition occurs. Therefore any flash point must be > 135 °C.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item has no flash point and/or no flammable vapour/air mixture was produced, up to 135°C the temperature at which decomposition occurs. Therefore any flash point must be > 135 °C at 101.325 kPa.

Executive summary:

The flash point was determined according to ASTM D7094, equivalent or similar to EU Method A.9, using an Eraflash flash-point tester in the closed cup method consistent with ISO 3679, ISO 2719, ASTM D93 and ASTM D7094: Modified Continuously Closed Cup Flash Point (MCCCFP) test under GLP. The Eraflash tester employs a small volume of test item which reduces the risk of fires or other uncontrolled reactions of substances with an unknown flash point. In the preliminary test, the test cup was filled with approximately 2 mL test item and placed in the holder of the flash-point tester. The sample was stirred during heating. The ignition of the sample vapour was performed by an electric arc and ignition was automatically detected by the flash point tester. The flash-point is automatically corrected for atmospheric pressure by the flash point tester. During preliminary testing starting at 25°C, an attempt was made to ignite the vapour of the test item for every 2°C temperature rise. The test cup was heated at a rate of 5 ± 0.5°C/minute. No flash-point was observed below the temperature at which reaction and/or degradation of the test item (i.e. 135°C) occurred. Therefore, the preliminary test was repeated. The temperature of the test item at the start of the additional test was 25°C. Starting at 25°C the ignition source was applied for every 2°C temperature rise. It was visually observed that the test item reacted and/or degraded at approximately 135°C. No flammable vapour/air mixture was produced at temperatures below the temperature at which reaction and/or degradation of the test item occurred. From this, it was concluded that the test item has no flash point. Due to decomposition and/or no flammable vapour/air mixture was produced. Under the conditions of the study, the test item has no flash point and/or no flammable vapour/air mixture was produced, up to 135°C the temperature at which decomposition occurs. Therefore any flash point must be > 135 °C at 101.325 kPa.

Description of key information

FP: > 135 °C at 101.325 kPa atmospheric pressure; since no flash point and/or no flammable vapour/air mixture was produced, up to 135°C the temperature at which decomposition was seen to occur: any flash point must be > 135 °C at 101.325 kPa, ASTM D7094, 2020

Key value for chemical safety assessment

Flash point at 101 325 Pa:

135 °C
