Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016-01-05
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
Version / remarks:
2003
Deviations:
no
GLP compliance:
no
Remarks:
The study was conducted under supervision of a quality assurance unit which had ensured e.g instrumentation validation, reagent/materials certification, analyst certification and providing standard operating procedures.
Type of method:
non-equilibrium method closed cup
Flash point apparatus:
Pensky-Martens apparatus
Key result
Flash point:
138.5 °C
Atm. press.:
1 013.25 hPa

Preliminary test

In the preliminary test the lowest temperature where an ignition was observed was 140.0 °C.

 

Main test

In the main test the lowest temperature where an ignition was observed was 138.0 °C.

The mean measured flash point is corrected to the ambient pressure to be 138.76 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 138.5 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was determined to be 138.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.
With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.
Executive summary:

A study was conducted according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2003) to determine flash point of the test item using the Pensky-Martens closed cup method. The start temperature for the main test (140 °C) was chosen based on preliminary test results. Approx. 70-72 g of the test item was filled in the cup and heated to the estimated temperature. The measured flash point at atmospheric pressure was corrected to a standard pressure of 1013 hPa. The flash point was determined to be at 138.5 °C (corrected to the ambient pressure).

Description of key information

The flash point of the test item was determined to be 138.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
138.5 °C
