2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to guideline
Guideline:
ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
Deviations:
not specified
GLP compliance:
not specified
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Key result
Flash point:
> 140 °C
Remarks on result:
other: The testing was stopped at 140°C in order to prevent the test substance from gelling.
Conclusions:
Under the study conditions, the flash point of the test substance was considered to be >140°C.
Executive summary:

A study was conducted to determine the flash point of test substance, DPHA using Pensky-Martens closed cup method according to the ISO Guideline 2719. The method required that the test start at 23°C below the flashpoint and be heated at 5-6°C/min to the flash point. The testing was stopped at 140°C in order to prevent the test sample from gelling. The exact flash point could not be determined but will be higher than 140°C. Under the study conditions, the flash point of the test substance was considered to be >140°C (Herssens, 2010).

Description of key information

The flash point of the test substance was determined using the Pensky-Martens closed cup method according to ISO Guideline 2719 (Herssens, 2010).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
140 °C
