Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 day
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Experiment conducted according to the method as described in the Setaflash manual and council regulation (EC) 440/2008 of 30 may 2008, Annex part A.9
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Council Regulation 440/2008
Deviations:
yes
Remarks:
start temperature was above the melt temperature of AHTN (~54 degrees Celsius).
Principles of method if other than guideline:
The flash point is determined by a Setaflash tester Closed Cup system. The sample was heated and exposed to a flame a regular time intervals. Flash point was determined by visual inspection of vapour ignition.
GLP compliance:
no
Type of method:
non-equilibrium method closed cup
Key result
Flash point:
> 100 °C
Remarks on result:
no flash point up to 100°C
Remarks:
Atm. pressure not given, but the test was performed under atmospheric conditions

The result of the control was satisfying, hence the results of the flash point of AHTN can be accepted. Sample: The flash points of AHTN were above 100oC for both measurements.

 

Conclusions:
The flash point of AHTN is above 100 degrees Celsius.
Executive summary:

The flash point is determined by a Setaflash tester Closed Cup system. The sample was heated and exposed to a flame a regular time intervals. Flash point was determined by visual inspection of vapour ignition. The flash point of AHTN is above 100oC. n-Dodecane was used a control and gave a satisfactory result, hence the determination of the AHTN flash point was accepted.

Description of key information

The flash point of the test item is above 100°C, tested in a GLP compliant EU method A.9 study (closed cup method).

Key value for chemical safety assessment

Additional information

Although the test item is a solid at room temperature, it melts at 54°C. It has been checked if the test item has a flash point between the melting point and 100°C. This is not the case, hence the flash point is above 100°C.
