Endpoint:
pyrophoric solids
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
documentation insufficient for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
Determination of lower limit concentration for establishment of a combustible aerosol (dust-air-mixture).
GLP compliance:
no

Lower limit of flammability for an aerosol of the test substance (dust-air-mixture): 10 mg/L (10000 mg/m³).

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 experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
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
Endpoint:
self-heating substances / mixtures
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 completely molten at 160°C
Endpoint:
flammability

Description of key information

not pyrophoric

not flammable on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Based on the chemical structure and experience in handling and use, pyrophoricity, self-heating and flammability on contact with water are 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:

No propagation of burning in a test according to EU Method A.10.

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