Flammability:
non flammable

Additional information

In accordance with Annex I, Section 2.1, Section 2.2, Section 2.3, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as readily combustible solid in class 4 Division 4.1, self-heating substance in Class 4 Division 4.2, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric liquid, pyrophoric solid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2 (the substance is a solid).
