Endpoint:

pyrophoric liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

15 July to 30 July

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

other: Regulation EC No. 440/2008 Method A.9.

Deviations:

no

Qualifier:

according to guideline

Guideline:

other: DIN EN ISO 3679 (2004)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Test procedure:

ignition time on contact with air

Temp.:

51 °C

Remarks on result:

ignition on contact with air (not further specified)

Conclusions:

Flash point was measured according to Regulation EC No. 440/2008 Method A.9 Flash Point CIPAC MT 12 (2009) and OPPTS Guideline 830.6315 (1996). The test item separated into two phases, a highly viscous larger phase and a smaller liquid phase.
In the main test the lowest temperature where an ignition was observed was 51,1 °C. The measured flash point corrected for air pressure is 51,2 °C. The resulting corrected flash point rounded down with an accuracy of 0,5 K is 51,0 °C.

Executive summary:

Deviations:

no

Seven different fast pyrolysis bio-oil samples were tested by a combustibility tester according to a UN test method .The results were evaluated by criteria described in the method as sustained combustion or no sustained combustion. In the test of samples 1 -7 no sustained combustibility was detected.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The test report from VTT shows that seven different types of Bio-Oil, which were tested, did not sustain combustion.

Executive summary:

Seven different fast pyrolysis bio-oil samples were tested by a combustibility tester according to a UN test method

(Recommendations on the Transport of dangerous goods-The manual on Tests and Criteria, Part III, test L.2. Sustained combustibility test (United Nations New York and Geneva, 2003)).

The results were evaluated by criteria described in the method as sustained combustion or no sustained combustion. In the test of samples 1 -7 no sustained combustibility was detected.

Description of key information

The measured flash point for Fast Pyrolysis Bio-oil is 51.7 °C. If the flashpoint is <=60 °C (closed cup test), the product is classified as flammable liquid unless it does not sustain combustibility and the flash point is > 35 °C, but <=60°C.
The test report from VTT showed that seven different types of fast pyrolysis bio-oil, which were tested, did not sustain combustion. 

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Flashpoint for Fast Pyrolysis Bio-Oils is normally between +40 - +100 °C. If the flashpoint is <=60 °C (closed cup test), the product is classified as flammable liquid unless it does not sustain combustibility and the flash point is > 35 °C, but <=60°C.

The measured flash point for Fast Pyrolysis Bio-oil is 51.7 °C.

The test report from VTT shows that seven different types of Fast Pyrolysis Bio-Oil, which were tested, did not sustain combustion. For this reason the product is not classified as flammable.
