Referenceopen allclose all
A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 L/kg of the substance per hour.
The molecular structure of the test substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test substance was dissolved in water during the determination of the water solubility. It demonstrated that the test substance does not ignite spontaneously in contact with water.
The flame from the gas burner did ignite the test substance pile. The test substance melted, glowed, expanded, burned with a blue yellow flame, and turned into a black residue. White smoke was observed. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed.
A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air.
The molecular structure of the test substance does not contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during the determination of the physico-chemical properties. It demonstrated that the test substance does not ignite in contact with air.
Description of key information
Flammability.solid - The substance does not propagate combustion along 200 mm length of the pile within 4 minutes. The flame from the gas burner did ignite the test substance pile. The test substance melted, glowed, expanded, burned with a blue yellow flame, and turned into a black residue. White smoke was observed. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed. In a GLP-compliant study performed in accordance with UN-MTC Section 33.2.1 (Test N.1) and EC A.10, the substance has been determined to be 'not highly flammable' by ignition.
Fammability contact with water - A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 L/kg of the substance per hour. The molecular structure of the test substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test substance was dissolved in water during the determination of the water solubility. It demonstrated that the test substance does not ignite spontaneously in contact with water. From a GLP-compliant statement based on structural features and experience in handling, it was concluded that the substance is not highly flammable in contact with water.
Pyrophoric properties - A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air. The molecular structure of the test substance does not contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during the determination of the physico-chemical properties. It demonstrated that the test substance does not ignite in contact with air. From a GLP-compliant statement based on structural features and experience in handling, it was concluded that the substance has no pyrophoric properties.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test.
