Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2018-02-28 to 2018-03-07
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes (incl. QA statement)

- Purity: 99.35%
- Expiration date of the lot/batch: January 2019
- Stability under test conditions: Room temperature
Key result
Test procedure:
step 4
Max. rate of gas release:
0 L/kg h
Identity of evolved gas:
not applicable as no gas evolved
Remarks on result:
only step 4 of test procedure conducted because substance does not react violently with water

Interpretation of results:
not classified based on GHS criteria
Conclusions:
For the initial tests, no gas generation or spontaneous ignitions were observed. For the final test, the generation of a flammable gas was less than 1 l.kg-1 of the substance per hour. The substance is therefore not classified as a substance which emits flammable gases in contact with water.
Endpoint:
pyrophoric liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2018-02-20
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 (incl. QA statement)
Specific details on test material used for the study:
- Batch No.of test material: 20141015
- Purity: 99.35%
- Expiration date of the lot/batch: January 2019
- Stability under test conditions: Room temperature
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition within 5 minutes
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 is not pyrophoric.

Description of key information

The test substance is not considered a substance which emits flammable gases after contact with water or a pyrophoric substance (K1, Dekra, 2018).

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 pyrophoric or as a substance which emits flammable gases in contact with water.
