Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
15 September 2017 - 18 September 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Specific details on test material used for the study:
- Batch n°: DR74271215
- Production release date: 30 November 2015
- Expiry date: 30 December 2018
- Purity (on dry basis): 98.2%, water content: 0.05%
Test procedure:
step 1
Remarks on result:
no reaction with water observed
Test procedure:
step 2
Remarks on result:
no reaction with water observed
Test procedure:
step 3
Remarks on result:
no reaction with water observed
Test procedure:
step 4
Remarks on result:
no reaction with water observed

No gas generation or spontaneous ignitions were observed during any of the initial tests (test 1 - test 3) and in the final test (test 4).

It is concluded that the sample does not generate flammable gases in contact with water and is therefore non-hazardous.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
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:
22 September - 25 September 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Specific details on test material used for the study:
- Batch n°: DR74271215
- Production release date: 30 November 2015
- Expiry date: 30 December 2018
- Purity (on dry basis): 98.2%, water content: 0.05%
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition on contact with air (not further specified)
Key result
Test procedure:
effect on filter paper
Remarks on result:
no charring

Porcelain cup test (test 1): no ignition and no reaction was observed in any of the 6 repetitions.

Filter paper test (test 2): no ignition, no charring and no reaction was observed in any of the 3 repetitions.

Since no ignitions or charring was observed during any test, the sample is considered not pyrophoric.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item was determined to be not pyrophoric.
Endpoint:
flammable solids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Endpoint:
self-heating substances / mixtures
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Description of key information

The substance is not considered a pyrophoric substance according to a GLP study (K1, Dekra, 2017). In addition, the test substance does not generate flammable gases in contact with water (K1, Dekra, 2017). Finally, the test substance is not considered as a flammable and a self-heating substance (no test performed, waiving because the substance is a liquid).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

The substance does not need to be classified as flammable, self-heating or pyrophoric. In addition, the substance does not need to be classified as a substance that generate flammable gases in contact with water.
