Results and discussion

Any other information on results incl. tables

In contact with the flame of the gas burner the test substance melted and turned into a black residue. Grey smoke was observed. After removal of the ignition source, no propagation of combustion of the test substance was observed.

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 litre/kg of the substance per hour.

 

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.

 

In conclusion,V173520 is considered ‘not highly flammable’ in contact with water.

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 is shown in paragraph 6.1. 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 this project. It demonstrated that the test substance does not ignite in contact with air.

 

In conclusion,V173520has no pyrophoric properties.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The preliminary screening test was performed for the determination of the flammability of V173520.

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required.

Based on the results obtained, the test substance is considered ‘not highly flammable’.

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.
 
In conclusion,V173520 is considered ‘not highly flammable’ in contact with water.
