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 December 18 to 24, 2007
- 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 was reported. The substance is considered to be adequately characterised with its purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: ISO 3679-1983 (E)
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: Anon (1983) Paints, varnishes, petroleum and related products - Determination of Flash Point - rapid equilibrium method
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: Anon (1989) Flash point of liquids by Setaflash closed cup apparatus
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: ASTM D3278-89
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP Compliance Programme (inspected on August 21, 2007/ signed on October 15, 2007)
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Flash point:
- 135 °C
- Atm. press.:
- 102.41 kPa
- Flash point:
- 135 °C
- Atm. press.:
- 101.3 kPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Despite the test substance is solid at ambient temperature, this study is relevant for classification purpose, as the melting point is below the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria), therefore the substance is liquid in this range.
As the test result is above these criteria, the substance is NOT classified as a flammable liquid in the two systems. - Executive summary:
The flash point of the test substance was determined under GLP according to ISO Method (listed in EU A.9 guideline), using a closed cup equilibrium method.
The flash point of test substance has been determined to be 135 ± 2 °C, as corrected to normal atmP.

Description of key information
The substance is NOT classified as flammable (liquid) according CLP and GHS criteria.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 135 °C
Additional information
A fully reliable experimental study, conducted according to a recognized EC method (closed cup), is available. It is considered as a key study, and the result is retained as key data.
Despite the substance is solid at ambient temperature, this study is relevant for the classification regarding flammable properties, as low melting point leads to liquid state below the classification temperature criteria:
The result is above the thresholds of Regulation (EC) 1272/2008 (CLP) and UN Globally Harmonised System (GHS), respectively 60°C and 93°C, therefore the test substance is NOT classified as flammable liquid in the two systems.
