Description of key information

16.0  µm diameter at 12.2 % oversize
8.0 µm diameter at 66.3 % oversize
1.0 µm diameter at 97.1 % oversize

Additional information

The test substance could not be analysed in accordance with the OECD Guideline for Testing of Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter Distributions".

The diameter in µm were:

16.0 at 12.2 % oversize

8.0 at 66.3 % oversize

1.0 at 97.1 % oversize

Median of mass distribution (diameter), mean of two analysis: 9.9 µm

The 8.1 % in volume of the test item has a particle size <= 4 µm (respirable fraction (the mass fraction of particles that reaches the alveoli) (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.
