Description of key information

Flue Dust: 0 - 175 µm, measured by laser granulometry
Respirable fraction: 10 %, calculated by SWeRF method
MMAD = 19.4 µm
GSD = 3.53

Additional information

The particle size distribution of the flue dust sample "Flue Dust T (REACH) was measured by laser granulometry (CILAS 1064). This measurement gives the particle size distribution in the range between 0.10 and 20000 µm.

The test item has a particle size range between 0 and 175 µm. The respirable fraction was calculated due to the SWeRF method.

Particle size distribution may vary, as Flue Dust is a UVC substance with a broad range in composition and constituents.
