particle size < 100 µm: 19%
particle size < 10.0 µm: 2.46%
particle size < 5.5 µm: 1.13 %

Additional information

The method satisfies the requirements of OECD Guideline 110. Particle size < 100 µm: inhalable fraction (screening test, sieve method); particle size < 10 µm: thoracic fraction and particle size < 5.5 µm: respirable fraction (both: definitive test, cascade impactor method).
