Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2018-05-17 - 2018-10-09
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:
Aug 1996
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: UN Handbook "Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria" Rev. 6, 2015, Method 32.4 "Test methods used for determining flash point and viscosity"
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Specific details on test material used for the study:
The test item was stored in a tightly closed vessel at room temperature (18.2 - 22.1 °C).
Key result
Flash point:
56.5 °C
Remarks on result:
other: see 'Remarks'
Remarks:
not atm. press. stated in study report, mean of two determinations
Interpretation of results:
other: Category 3 (flammable liquids) based on EU GHS criteria
Conclusions:
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 56.5 ± 1.0 °C (corresponding to 329.7 ± 1.0 K).
Executive summary:

The study was performed according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4 under GLP-conditions.

First, a safety test was performed: approx. 3 mL of the test item was heated with a Bunsen burner up to the temperature of 160.0 °C. The appearance had not changed after cooling down.

Then, a pre-test and a main test with two experiments were performed using a flashpoint tester.

The flashpoint of Hydroxyacetone is stated as 56.5 ± 1.0 °C (corresponding to 329.7 ± 1.0 K).

This value is the mean value of two independent determinations.

Description of key information

The study was performed according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4 under GLP-conditions.

First, a safety test was performed: approx. 3 mL of the test item was heated with a Bunsen burner up to the temperature of 160.0 °C. The appearance had not changed after cooling down.

Then, a pre-test and a main test with two experiments were performed using a flashpoint tester.

The flashpoint of Hydroxyacetone is stated as 56.5 ± 1.0 °C (corresponding to 329.7 ± 1.0 K).

This value is the mean value of two independent determinations.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
56.1 °C

Additional information

No atmospheric pressure was stated in the study report, nevertheless 101 325 Pa is the pressure of room conditions which are applicable for the performed test and therefore for chemical safety assessment.
