Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Test dates: April 22 to August 24, 2005
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The substance is considered to be adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
GLP compliance:
yes (incl. QA statement)
Remarks:
effective 27/09/2004
Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
no data
Specific details on test material used for the study:
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature protected from direct sunlight.
Key result
Flash point:
122 °C
Atm. press.:
ca. 101 325 Pa

In a first test, the temperature was increased by successive steps of +5.0 °C, using 4 mL of sample.

Flashing occurred at 125°C.

The procedure was reproduced in duplicate using a new 4.0 mL sample for each replicate test, and the temperature was regularly increased by successive steps of 0.5 °C. Flashing occurred at 122.0°C in both cases.

Mean Flash Point = 122.0°C.

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
The flash point of test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was determined under GLP according to EU Method A.9, using a closed cup Setaflash apparatus method.

After a screening determination, two main runs were performed, and found identical. The average result was retained.

The flash point of the test substance has been determined to be 122°C.

Description of key information

The substance is NOT classified as flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
122 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Therefore it is considered as a key study, and the result is retained as key data.
