non flammable

Additional information

Three flammability tests were performed with the test substance. In the first test, flammability of solids was assessed according to EU Method A.10 (Baker, 2010). In the second test, flammability in contact with water was assessed according to EU method A.12 (Baker, 2010). The third test assessed the pyrophoric properties of the test substance according to EU method A.13 (Baker, 2010). The results of these tests were that the test substance is not flammable, not flammable in contact with water and has no pyrophoric properties.
