Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 1992
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
The study was conducted according to an internationally recognised method, and under GLP. However, some informations are missing in the experimental report. Purity is specified in the report, and isomers composition is available from the notifier. Therefore full validation cannot apply.
according to guideline
EU Method A.9 (Flash-Point)
according to guideline
ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)
Version / remarks:
GLP compliance:
yes (incl. QA statement)
Inspected on 19 June 1990. Signed on 5 October 1990.
Type of method:
non-equilibrium method closed cup
Flash point apparatus:
Pensky-Martens apparatus
Dynamic viscosity of test material:
(no data)
Specific details on test material used for the study:
Storage condition of test material: metal can, under refrigeration at 2-8°C in the dark.
Key result
Flash point:
160 °C
Atm. press.:
ca. 1 atm

Atmospheric pressure was not recorded (assumed to be ambient).

Interpretation of results:
GHS criteria not met
GHS and EU-CLP criteria not met
The flash point of the 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 measured, under GLP, according to ASTM D93-77 method (listed in EU A9 guideline), using a Pensky-Martens apparatus.

The flash point of the test substance was determined to be 160°C.

Description of key information

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

Key value for chemical safety assessment

Flash point at 101 325 Pa:
160 °C

Additional information

A reliable study, conducted according to a recognized EC method and under GLP, is available. Despite restrictions due to missing information in the report, it is considered as a key study. The result is retained as key data for purpose of CSA.

It should be noted that, due to the multi-isomers nature of the substance tested, this result may refer to the most flammable one.

This result is relevant for the classification regarding flammable properties.
