Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
08 Dez 2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
no
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
> 2 400 s

The substance propagated combustion along 200 mm in the preliminary test only after 40 minutes.

Therefore the burning rate test did not need to be done.

Interpretation of results:
not classified based on GHS criteria
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

non flammable
no pyrophoricity
no flammability on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The substance is non-flammable based on the test according to EU A.10 (preliminary test; very slow propagation of combustion). Based on experience in handling and use and the chemical structure, pyrophoricity and flammability on contact with water are not to be expected. Since the substance is produced and formulated only in wet processes, self-heating is not expected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification:

Based on the EU A.10 test, the substance is non-flammable.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

Based on the fact that the substance is produced and formulated only in wet processes, self-heating of the substance can be excluded.
