flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
01-05-2012 - 02-05-2012
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
yes (incl. QA statement)
Type of method:
closed cup
Specific details on test material used for the study:
- Name of test material (as cited in study report): Jeffcat ZR50
- Physical state: Liquid
- Batch: PFW100207
- Composition of test material, percentage of components: contains 0.03% water
- Storage conditions: in cool, well-ventilated area
Flash point:
132 °C
Atm. press.:
102 kPa
Remarks on result:
other: No correction for barometric pressure required.

Available MSDS data stated a flash point of 141°C. Therefore testing was initiated at 118°C (23°C below expected flashpoint, in accordance with test standard).

On runs 2 and 4 no flash point was observed and the test flame began to extinguish when directed into the cup. However in the other 3 runs a flash was observed at 132, 134 and 134 °C.

On completion of testing, the sample had turned dark orange.

Interpretation of results:
GHS criteria not met
The flash-point of the substance was determined to be 132°C at 102.0 kPa.

Description of key information

The flash-point of the test substance was determined in a GLP-compliant study according to test method EC A.9 to be 132 °C at 102.0 kPa, following the closed cup method of Pensky-Martens (Younis S, 2012).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
