flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-12-14 TO 2010-06-07
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
yes (incl. QA statement)
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Dynamic viscosity of test material:
4960 mPa.s at 20°C
Flash point:
142.5 °C
Atm. press.:
1 013 hPa
Flash point:
145.5 °C
Atm. press.:
1 013 hPa
Interpretation of results:
GHS criteria not met
GHS and EU-CLP criteria not met
Under the conditions of this study, a flash point of 142.5/145.5°C was determined.
Executive summary:

The flash point of the substance was studied according to EU test method A.9 with the Pensky-Martens method (closed cup). Two value of flash point were determined: 142.5°C and 145.5°C at 1013 hPa. The measured flash point does not relate the flammability properties of the registered substance but rather flammable properties of butanone oxime (CAS 96-29-7) which is released by thermal decomposition (starting at ca. 120°C) of the registered substance.

Description of key information

The registered substance which exhibits a flashpoint of 144°C is not considered as flammable.  

Key value for chemical safety assessment

Flash point at 101 325 Pa:
144 °C
