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:
- 14 June to 09 August 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.6315 (Flammability)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on October 13 and 14, 2014 / signed on April 08, 2015
- Type of method:
- non-equilibrium method closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Key result
- Flash point:
- ca. 78 °C
- Atm. press.:
- ca. 101 325 Pa
- Interpretation of results:
- Category 4 (combustible liquids) based on GHS criteria
- Conclusions:
- The measured flash point is therefore 78.0 ± 0.5°C (corresponding to 351.2 ± 0.5 K).
- Executive summary:
The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a non-equilibrium closed cup method (ISO2719 - Part B).
The flash point of the test item has been determined under argon to be 78.0°C (351.2K), which is the mean value of two independent valid determinations.
The flash point of test substance is above the classification thresholds of 60°C of the Regulation (EC) No. 1272/2008 (CLP criteria) and lower than 93°C, the threshold of the UN Globally Harmonised System (GHS).
Therefore the test substance is NOT classified as a flammable liquid according to CLP criteria but is classified as a Flammable Liquid Category 4 according to UN Globally Harmonised System (GHS).
Reference
Pre-Test for Safety
A safety test was performed in study 15110601G906 determination of the boiling point (endpoint 4.3). A small amount of the test item was heated in a test tube in an aluminium block with a Bunsen burner. A boiling chain was observed at approx. 170 °C. The chain broke at 167°C. After cooling down visual no changes of the test item was observed.
Determination of the Flash point
No reproducible flash point could be measured when the test was performed without argon.

The reference measurement with Dodecan under argon was performed with 84.5 °C
Evaluation and Result
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 78.0 ± 0.5°C (corresponding to 351.2 ± 0.5 K).
Discussion
First a performance including two pre-tests and a main test with two experiments was conducted. No reproducible flash point could be measured when the study was performed without argon. a second performance including a pre-test and a main test with two experiments were performed under Argon using a flashpoint tester. This performance yield reliable results. The difference between the two values which were measured under Argon was below 2 K.
The reference measurement under argon was valid. For this reason, the determination was considered valid.
Description of key information
The substance is NOT classified as a flammable liquid according to Regulation (EC) N°1272/2008 (CLP criteria).
The substance is classified as Flammable Liquid Category 4 according to UN Globally Harmonized System (GHS criteria).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 78 °C
Additional information
The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a non-equilibrium closed cup method (ISO2719 - Part B). It was considered as a key study. The result was retained as key data for purpose of CSA.
This study was relevant for the classification regarding flammable properties.
