- Executive summary:
The determination of the Particle Size Distribution of CR SR94 was performed in accordance with OECD Guideline no. 110.
The method can only be applied to water-insoluble (<10^-6 g/L), powdered type products.
The Particle Size Distribution of CR SR94 was determined to be 53.9 μm.
