Flash point:
145.5 °C
Atm. press.:
1 013 hPa
Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
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
