Description of key information

The procedures used in the study were in accordance with guidelines: 
Guidance Document on the Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances, EUR 20268 EN (2002)
Standard ISO 2591-1 Test sieving - Part 1: Methods using test sieves of woven wire cloth and perforated metal plate.

GLP compliance: yes

Additional information

Particle size distribution of test substance, Ashes (residues) – Biomass Combustion, is characterized by these values:

16,84% of its particles are smaller than 0.08 mm and this fraction was studied using the laser diffraction analysis which resultes in value D90 when more than 90% particles are smaller than 0.046 mm.

Standard uncertainty is equal to standard deviation.
