Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 17 June to 11 November 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognized method, and under GLP. No deviation was reported. Test substance is adequately specified. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
- Version / remarks:
- 2004 (E)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
- Version / remarks:
- 1989
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 05 July 2016 / signed on 28 October 2016)
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Key result
- Flash point:
- 93 °C
- Atm. press.:
- 101 325 Pa
- Interpretation of results:
- Category 4 (combustible liquids) based on GHS criteria
- Remarks:
- NOT classified based on CLP criteria and Classified as COMBUSTIBLE LIQUID Cat. 4 based on GHS criteria
- Conclusions:
- The flash point of the test item has been determined to be 93°C.
The flash point of test substance is above the classification thresholds of 60°C of Regulation (EC) No. 1272/2008 (CLP criteria). Therefore the test substance is NOT classified as a flammable liquid based on the CLP criteria.
However, the flash point of test substance is at the classification threshold of 93°C (GHS criteria). Therefore the test substance is Classified as COMBUSTIBLE LIQUID Cat. 4 based on the GHS criteria. - Executive summary:
The flash point of the test item was determined under GLP according to EU Method A.9 (Flash Point), using a closed cup equilibrium method (ISO 3679 and ASTM D 3278).
The main test was performed in duplicate, and the mean result was retained, and corrected to normal atmospheric pressure:
Observed flash point: 93°C
Atmospheric pressure: 100.9 kPa
Corrected flash point: 93.1 °C
The flash point of the test item has been determined to be 93 ± 2 °C.

Description of key information
The substance is NOT classified as flammable liquid according to CLP criteria and is classified as COMBUSTIBLE LIQUID Cat. 4 according to UN GHS criteria.
Note that the result obtained on this kind of substance should be largely influence by small amounts of volatile constituents and the result doesn't represent the major part of the substance.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 93 °C
Additional information
A GLP fully reliable experimental study, conducted according to recognised ISO/ASTM/EC method (closed cup equilibrium method) is available. It is considered as a key study. The result is retained as key data.
This study is relevant for the classification regarding flammable properties.
