Any other information on results incl. tables

Preliminary test

No flammable vapour/air mixture was produced at temperatures below the temperature at which pressure error occurred (i.e. at 136, 132 and 139°C in test 1, 2 and 3, respectively). From this, it was concluded that the test substance has no flash point below 132°C.

Applicant's summary and conclusion

Conclusions:
In a GLP-compliant study in accordance with UN-MTC Section 32.4, EC A.9, ASTM D7094 and ISO 3679 using the Pensky-Martens closed-cup method, the flash point of the substance has been determind as >132°C.
