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:
- 05 JUL 2021 to 04 OCT 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 31 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.6315 (Flammability)
- Version / remarks:
- August 1996
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN Handbook “Manual of Tests and Criteria” Rev. 7, 2019, Method 32.4 “Test methods used for determining flash point and viscosity”
- Version / remarks:
- Rev. 7, 2019
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- non-equilibrium method closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Flash point:
- 129.5 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: flash point was internally corrected to standard pressure
- Interpretation of results:
- other: EU GHS criteria not met
- Conclusions:
- The measured flash point is 129.5 °C (corresponding to 402.7 K).
- Executive summary:
The flash point of the sample was assessed during a GLP-study according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4.
A small amount (approx. 2 mL) of the test item was heated in a test tube in an aluminium block with a Gas burner. A boiling chain was observed at 270.2 °C. The chain broke at 255 °C. After cooling, the test item remained as a yellowish liquid.
Then, a pre-test and a main test with three experiments were performed using a flashpoint tester.
The flashpoint of N-Butyldiethanolamine is stated as 129.5 °C (corresponding to 402.7 K). This value is the mean value of two independent determinations (second and third determination.

FINDINGS
Pre-Test for Safety
Observations | Temperatures in °C |
Individual air bubbles, the color was slightly yellow | from 140 |
Several air bubbles visible | from 235 |
Bubbles came faster | from 248 |
Boiling chain, gas burner off | from 270.2 |
Chain broke | 255 |
After cooling down the test item remained yellow.
Determination of the flash point
Program | Expected flash point (setting) in °C | Flash point (found) in °C | Mean in °C | Notes |
Search | 255 | 130.7 | not used for calculation (pre-test) | |
EN ISO 2719-A | 131 | 133.5 | - | not used for calculation |
131 | 129.5 | 129.5 | difference < 2 K | |
131 | 129.5 |
EVALUATION AND RESULT
The flash point is given as the mean value of the duplicate valid determination (second and third determination).
The deviation of the first flash point value to the second and third flash point value were above 2 K, therefore this value was not taken for evaluation.
The measured flash point is therefore 129.5 °C (corresponding to 402.7 K).
DISCUSSION
The difference between the two valid values which were measured was below 2 K. For this reason, the determination was considered valid.
