flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
June 26, 2012
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Well conducted study under internal management system, according to EC Regulation No 440/2008, Guideline A9 and to ASTM D93, certificate of analysis inserted in the report.
according to guideline
EU Method A.9 (Flash-Point)
according to guideline
ISO No., other: ASTM D93-08, Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester, 2008
GLP compliance:
Type of method:
closed cup
Flash point:
111 °C
Atm. press.:
102.2 kPa

Calibration and accuracy

The measured value with n-undecane after correction for atmospheric pressure was 70.9°C.

This value is within the acceptance limits.


The accuracy of the method varies according to the flash point range used. The maximum estimated accuracy is ±2°C.


The estimated accuracy of the manometer ± 0.1 kPa.


Flash point of test substance

The determination of the flash point of the test substance was carried out in duplicate.

- first result : 111.1°C

- second result:            111.1°C

- atmospheric pressure : 102.2kPa

- corrected flash point  : 110.9°C


This means that the flash point of the test substance is 111°C.

The flash point of citraconic anhydride is 111°C.
Executive summary:

The flash point of citraconic anhydride was determined in duplo according to toEC Regulation No 440/2008, Guideline A.9 , and according to ASTM D93 and in accordance with European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008 .

 The flash point of citraconic anhydride is 111°C.

Description of key information

The flash point of citraconic anhydride is 111°C. 

Key value for chemical safety assessment

Flash point at 101 325 Pa:
111 °C
