flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental dates: 06-08 December 2016
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The test substance is adequately characterised. Therefore full validation applies.
according to guideline
EU Method A.9 (Flash-Point)
according to guideline
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
ISO 3679-2004 (E), Second Edition – 2004-04-01, P1-18
according to guideline

Key result
Flash point:
118 °C
Atm. press.:
101.325 kPa

Detailed observations are available in the study report.

Measured Flash Point = 118°C

Atmospheric pressure: 101.6 kPa

Corrected flash point: 117.9 ºC
Accuracy: ± 2 °C

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 classified as a flammable liquid.
Executive summary:

The flash point of the test substance was measured under GLP according to ISO 3679 (listed in EU guideline A.9), using a closed cup equilibrium method.

The flash point of test substance has been determined to be 118 ± 2 °C, corrected to normal atmP.

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:
118 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU/ISO method (equilibrium closed cup) and under GLP, is available. It is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties. (see IU Section 4.13 for justification of non-classification)
