Key result

Flash point:

86.5 °C

Atm. press.:

ca. 101.5 kPa

Measurement (repeat determination)

Temperature of Initial Ignition Source Application: 60.0°C / 60.0°C

Atmospheric Pressure: 101.8 kPa / 101.3 kPa

Flash Point (Uncorrected): 86.7°C / 86.7°C

Flash Point (Corrected): 86.5°C / 86.5°C

Interpretation of results:

GHS criteria not met

Conclusions:

A flash point value of 86.5°C at atmospheric pressure was determined for the substance using a relevant test method. The result is considered to be reliable.

Executive summary:

Octan-1-ol was determined according ASTM D93. The flash point was determined to be 86.5 °C at atmospheric pressure.

Description of key information

The flash point of octan-1-ol is 86.5°C at 1013 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

86.5 °C

Additional information

A flash point value of 86.5°C at 1013 hPa was determined for octan-1-ol with the use of non-equilibrium closed-cup method in accordance with ASTM-D93. The result is considered to be reliable and is selected as key study.

It is supported by a value of 81°C, taken from a source of hazard reference data (the online International Chemical Safety Cards of WHO IPCS).

A flash point value of 86.5°C and boiling point of 194°C indicate that octan-1-ol should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

The flash point of Category substances follow a predictable trend of increasing flash point temperature with increasing chain length together with increasing boiling point and decreasing vapour pressure.
