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:
- 18. July 2017-03. August 2017
- 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. No deviation was reported. Test substance is adequately specified. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.6315 (Flammability)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN Manual Test Methods 32.4
- 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:
- 57.5 °C
- Atm. press.:
- 101 325 Pa
- Remarks on result:
- other: The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 57.5 °C (corresponding to 330.7 K) at 101325 Pa.
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- The flash point of test substance is below the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). The substance is classified as flammable liquid category 3 according to CLP and UN GHS criteria.
- 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).
First, the pre-test for safety was performed. When heating a sample of the test item in a aluminium block with a busen burner, a bubble chain was observed at approx. 170 °C. The chain broke at approx. 167 °C. After cooling down no changes were visible.
The flashpoint of the test item is stated as 57.5°C at 101325 Pa (corresponding to 330.7K).
This value is the mean value of two independent determinations.

Findings
Pre-Test for Safety
Formation of bubbles was observed at 170°C. The chain of bubble broke at 167°C. After cooling down, no further changes of the test item were observed.

Evaluation and Result
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 57.5°C (corresponding to 330.7 K) at 101325 Pa.
Discussion
The difference between the two values which were measured was below 2 °C. For this reason, the determination was considered valid.
The determination was considered valid.
Description of key information
The substance is classified as flammable liquid category 3 according to CLP and UN GHS criteria.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 57.5 °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).
First, the pre-test for safety was performed. When heating a sample of the test item in a aluminium block with a busen burner, a bubble chain was observed at approx. 170 °C. The chain broke at approx. 167 °C. After cooling down no changes were visible.
The flashpoint of the test item is stated as 57.5°C at 101325 Pa (corresponding to 330.7K).
This value is the mean value of two independent determinations.
It is considered as a key study. The result is retained as key data for purpose of CSA.
This study is relevant for the classification regarding flammable properties.
