*the mean value is calculated from test 1 and 2 and rounded to ±0.5°C.

Determination of the corrected flash-point:

Tc = T0 + 0.25 x (101.3 – p)

TC = corrected flash point to the standard atmospheric pressure (101.3 kPa)

T0 = measured flash point at actual atmospheric pressure

p = actual atmospheric pressure [kPa]

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
A flash point value of 57.5°C at 1013 hPa has been determined for the susbtance using an appropriate test method. The result is considered to be reliable.

Description of key information

Flash Point: 41 - 70°C (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
41 °C

Additional information

Several measured flash points are available for the substance. A measured flash point of 57.5°C at 1013 hPa was determined for the registered substance using a rapid equilibrium method in accordance with ISO 3679 Test Method (Haas 2011). In addition, in Wacker 2008, flash point values of 41°C, 57°C and 70°C were determined for the substance using a rapid equilibrium method in accordance with ISO 3679 Test Method.

Variations in the flash point values may be caused by variations in purity of the test substance and in the test method used. In particular, the presence of higher concentrations of volatile impurities such as methanol; a hydrolysis product of the substance, can result in lower flash points. The reliable values are used as weight of evidence. Each registrant will classify their product accordingly.

In available secondary sources to which reliability could not be assigned, flash point values of 46°C and 67°C were reported for the substance.

Flash point values of 41°C, 57°C, 57.7°C and predicted boiling point of 180°C indicate that the substance should be classified for flammability in accordance with the criteria of Regulation (EC) No. 1272/2008.

Flash point value of 70°C and predicted boiling point of 180°C indicate that the substance should not be classified for flammability in accordance with the criteria of Regulation (EC) No. 1272/2008.
