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
other:
Endpoint:
flammable solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
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

Description of key information

no flammablity, no pyrophoricity, no flammability on contact with water, not self-heating.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Based on chemical structure, flammability on ignition, pyrophoricity, flammability on contact with water, and self-heating properties are not expected.

In ashes (residues), cenospheres the elements are in their highest oxidation state and incapable for further reaction with oxygen.

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. The substance is not combustible therefore not considered to be classified as flammable solid or as pyrophoric.
