Description of key information

MMD (D50) = 120.9 µm

< 0 % in volume particle size < 4 µm

Additional information

The particle size distribution of the test item, determined according to internationally accepted guidelines ISO 13320, OECD TG 110 and EPA OCSPP 830.7520 are

D10 = 41.9 µm, D50, median particle size = 120.9 µm and D90 = 234.9 µm.

0% in volume of the test item has a particle size <= 4µm (respirable fraction - the mass fraction of particles that reaches the alveoli), as indicated in the CEN document, EN 481‘Workplace Atmospheres - size fraction definitions for measurement of airborne particles”, 1993.
