General Information

Implementation:
EU
Remarks:

Summary Tungsten metal powder is only classified under CLP and DSD for flammability and self-heating. The substance at the particle size tested (0.6-0.9 µm), classifies as a self-heating, category 2 substance under CLP. The flammability of tungsten powder is dependent on particle size.
Particle sizes <1.0 µm = category 1 flammability
Particle sizes 1.0 -1.5 µm = category 2 flammability
Particle sizes >1.5 µm = not classified for flammability

Particle size effects the Labelling signal word. Danger only applies to particles <1.0um. Warning applies to particles 1.0-1.5 um.
