Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-08-29 - 2018-10-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- 31 May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- The test item was stored in a tightly closed vessel at room temperature (17.8 - 22.1 °C).
- Key result
- Auto-ignition temperature:
- 310 °C
- Remarks on result:
- other: no atm. press. stated in study report
- Conclusions:
- The auto-ignition temperature of Hydroxyaceton is stated as 310 °C.
- Executive summary:
The auto ignition temperature was determined in three independent determinations under GLP-conditions according to EU A.15 method.. 310° C was the lowest value obtained in these determinations. The auto-ignition temperature of Hydroxyaceton was rounded down to a whole multiple of 5 °C and is stated as 310 °C.
Reference
DETERMINATION OF VISCOSITY
The test item was visually compared with the standard liquid viscosity (50 mPa*s). The viscosity of the test item was below 50 mPa*s.
RESULT
The requirements for repeatability of the DIN standard are stated as follows: The three lowest values of the main test have to lie within a range of 10 K (if auto ignition temperature is above 300 °C).
The following lowest values were recorded:
Table: Lowest values main test
Experiment | Value | Ignition delay | Drops used |
First test series | 312 °C | 5 s | 8 |
Second test series | 312 °C | 10 s | 12 |
Third test series | 310 °C | 3 s | 4 |
The lowest value of the auto ignition temperature is 310 °C. This value was determined using 4 drops test item. The test item showed auto ignition after 3 seconds.
The auto ignition temperature (result of repeated determinations) is the lowest value from the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 310 °C.
VALIDITY
In the DIN, the following limits are applied to the range of lowest values which may be used for evaluation: > 300 °C: difference between three values of the main test max. 10 K.
The three lowest values of the main test lay within a range of 10 K (as required for auto ignition temperatures above 300 °C). The largest difference between measured ignition temperatures was 2 K.
DISCUSSION
The study was conducted according to procedure and demands of EU-Method A.15 and DIN 51794. The acceptable range which is demanded in the DIN standard was fulfilled.
All measured values show good correlation. No observations were made which might cause doubts concerning the validity of the study outcome.
Description of key information
The auto ignition temperature was determined in three independent determinations under GLP-conditions according to EU A.15 method. 310° C was the lowest value obtained in these determinations. The auto-ignition temperature of Hydroxyaceton was rounded down to a whole multiple of 5 °C and is stated as 310 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 310 °C
Additional information
Tests were performed at room conditions. No atm. press. was stated for the result. But it is assumed that a pressure of 101 325 Pa is applicable for the result and therefore for chemical safetey assessment.
