Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2015-10-22
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO No., other: DIN EN ISO 2719 (2003):
Deviations:
no

Flash point apparatus:
Pensky-Martens apparatus
Key result
Flash point:
70.5 °C
Atm. press.:
1 013 hPa

In the preliminary test the lowest temperature where an ignition was observed was 71.0 °C.

In the main test the lowest temperature where an ignition was observed was 70.0 °C. The mean measured flash point corrected to standard atmospheric pressure of 1013 hPa is 70.73 °C, which - when rounded to the nearest 0.5°C - provides a final value of 70.5°C.

Replicate amount of test item (g) temperature (°C) Ignition air pressure (hPa) corrected flash point (°C)
1 60.00 70 + 1003.8 70.23
2 57.88 71 + 1003.8 71.23
Interpretation of results:
GHS criteria not met
Conclusions:
The flash point was determined to be 70.73 °C hPa by the Pensky Martens method.
Corrected to standard atmospheric pressure, this corresponds to 70.5°C at 1013 hPa.

Executive summary:

The flash point of the test item was measured using the Pensky Martens method, according Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 2719 (2003). The flash point of the test substance is 70.5 °C, average and corrected to standard atmospheric pressure.

Description of key information

The flash point was determined to be 70.5 °C at standard atmospheric pressure.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
70.5 °C

Additional information

For this endpoint, one experimental study is availble. The flash point of the test item was measured using the Pensky Martens method, according to Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 2719 (2003). The flash point of the test substance is 70.5 °C on average, corrected to atmospheric pressure (1013 hPa).

According to the CLP Regulation EC 1272/2008 (Annex I: 2.6) the substance does not have to be classified as flammable liquid because the measured flash point is above 60 °C.
