Key result

Flash point:

17 °C

Atm. press.:

1 013 hPa

Remarks on result:

other: average corrected and rounded down to the nearest multiple of 0.5 °C

Preliminary test:

In the preliminary test the lowest temperature where an ignition was observed was 16.0 °C.

Main test:

amount of test item / g	temperature / °C	ignition (+/-)	air pressure/ hPa	flash point (corr.)/ °C
66.44	17.0	+	1004.9	17.20
66.51	17.0	+	1003.8	17.23

In the main test the lowest temperature where an ignition was observed was 17.0 °C. The mean measured flash point is corrected to the ambient pressure to be 17.22 °C. The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 17.0 °C.

Interpretation of results:

Category 2 (highly flammable liquids) based on GHS criteria

Conclusions:

The test item has a flash point of 17.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C).

Executive summary:

In the current study the flash point of the test item was determined according to Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 13736 (2013).

The flash point of the test item was determined to be 17.0°C (average corrected and rounded down to the nearest multiple of 0.5°C).

Description of key information

For this endpoint one experimental study is available. The flash point was determined according to EC method A.9, in closed cup using a Abel apparatus. The flash point was found to be 17.0°C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

17 °C

Additional information

According to the results of the test on the flash point, the test item is classified as following:

UN Transport Regulation: As the test item has a boiling range of 108 - 111 °C (see Study No. CSL-16-2233.01), (> 35 °C) and a measured flash point of 17.0 °C (<23 °C), it has to be classified in class 3 as flammable liquid of Packaging Group II.

GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): As the test item has a measured flash point of 17.0 °C (< 23 °C), it has to be classified as highly flammable liquid of category 2 and has to be marked with the warning "H225: highly flammable liquid and vapour".
