Key result

Test procedure:

step 1

step 2

step 3

step 4

Remarks on result:

no reaction with water observed

Remarks:

No gas generation or spontaneous ignitions were observed during any of the tests.

No ignition was observed on all the tests. Therefore, the test substance is not considered to be flammable in contact with double-distilled water.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No gas generation or spontaneous ignitions were observed during any of the tests. Therefore, it can be concluded that the test substance does not generate flammable gases in contact with water.

Endpoint:

pyrophoric liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

23 September - 16 November 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.13 (Pyrophoric Properties of Solids and Liquids)

Deviations:

no

GLP compliance:

yes

Specific details on test material used for the study:

- Analytical purity: 94.55 %
- Expiration date: 31 December 2017
- Storage condition: at room temperature

Key result

Test procedure:

other: via a syringe

Remarks:

The test is performed 6 times

Remarks on result:

no ignition within 5 minutes

Remarks:

No ignition and no reaction observed

Key result

Test procedure:

effect on filter paper

Remarks:

The test is performed 3 times

Remarks on result:

no ignition within 5 minutes

Remarks:

No ignition, no charring and no reaction observed

No ignition or charring was observed during any test. The sample is therefore not pyrophoric.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No ignition nor reaction was observed during any test. The sample is therefore not a pyrophoric liquid.

Description of key information

Based on a GLP study (K1, Foster, 2016) according to the EU methods A.12 and A.13 the test substance does not emit flammable gases in contact with water and has no pyrophoric properties, respectively.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The test substance does not emit flammable gases in contact with water and has no pyrophoric properties and based on the flash point determination (>110°C, see 4.11 Flash point), the test substance is not considered a flammable liquid. Therefore, the substance is not classified for flammability.
