Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From July 2016 to May 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)

according to
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Deviations:
yes
Remarks:
temperature increments of 5 °C were made instead of 10 °C. This deviation did not affect the quality or the interpretation of the results obtained.
GLP compliance:
yes (incl. certificate)
Type of method:
equilibrium method closed cup
Flash point apparatus:
other: Normalab NPV 310

No, the test was

evaporated.

At 50.0 °C, the test item was completely evaporated before the presentation of the flame. thus the test was stopped and therefore no main test was performed.

As a conclusion, no flash point was observed up to 50.0 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
No flash point was observed up to 50.0 °C (corrected value).
Executive summary:

The determination of the flash point of the test item was performed in closed cup and according to the Commission Regulation EC A.9 method and ISO Standard 3679 (March 2015).

No flash point was observed up to 50.0 °C (corrected value). Indeed at 50°C the test item was totally evaporated.

The boiling point was found to be 47.7 °C in a reliable OECD test.

Description of key information

One reliable study is available. In this study, the flash point of the test item was determined according to the EC A9 method of the Commission Regulation (EC) No. 440/2008 and the ISO Standard 3679 (March 2015). This study was GLP compliant.

As a result, no flash point was observed up to 50.0 °C. Indeed at 50°C the test item was totally evaporated.

Key value for chemical safety assessment
