Results and discussion
Any other information on results incl. tables
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 surface tension and water solubility. It demonstrated that the test substance does not ignite spontaneously in contact with water.
In conclusion, CMO is considered not highly flammable in contact with water.
Applicant's summary and conclusion
- Interpretation of results:
- other: not highly flammable in contact with water
- Conclusions:
- In conclusion, CMO is considered not highly flammable in contact with water.
