Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
30 September 2012 to 9 October 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
yes
Remarks:
Due to instrument failure atmospheric pressure not measured. Historical data used to determine minimum and maximum atmospheric pressure. The resulting pair of corrected flash point values were within ± 2°C of the observed flash point.
GLP compliance:
yes (incl. certificate)
Type of method:
closed cup
Key result
Flash point:
>= 157 - <= 161 °C
Atm. press.:
>= 95.79 - <= 103.93 kPa
Remarks on result:
other: Atmospheric pressure not measured. Historical data used to quote minimum and maximum atmospheric pressure.

Historical data used to determine minimum and maximum atmospheric pressure. The resulting pair of corrected flash point values were within ± 2°C of the observed flash point.

As the flash point is > 60°C the substance does not meet the criteria for a flammable liquid.

Conclusions:
The substance as a 50% w.w. concentration in pharmaceutical white oil was determined to have a flash point of 159°C (not corrected to standard atmospheric pressure).
Executive summary:

The substance as a 50% w.w. concentration in pharmaceutical white oil was determined to have flash point of 159°C (not corrected to standard atmospheric pressure). The flash point of the test item was determined in a GLP-compliant study following EC 440/2008 A9 method (Harlan 2013). The study is considered reliable with restrictions and relevant for use for this endpoint. As the flash point is > 60°C the substance does not meet the criteria for a flammable liquid.

Description of key information

The substance as a 50% w.w. concentration in pharmaceutical white oil was determined to have a flash point of 159°C (not corrected to standard atmospheric pressure). As the flash point is > 60°C the substance does not meet the criteria for a flammable liquid.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
159 °C

Additional information

The flash point of the test item was determined in a GLP-compliant study following EC 440/2008 A9 method (Harlan 2013).
