Two test series of at least 3 measurements each were performed with the test item.

 

Test series 1

D₁₀:         9.9 µm                                                              Standard deviation: 0.18 µm

D₅₀:         82.3 µm            (Median diameter)                      Standard deviation: 1.05 µm

D₉₀:         222.2 µm                                                           Standard deviation: 2.34 µm

 

Test series 2

D₁₀:         9.6 µm                                                              Standard deviation: 0.09 µm

D₅₀:         79.4 µm            (Median diameter)                      Standard deviation: 0.19 µm

D₉₀:         215.5 µm                                                           Standard deviation: 0.50 µm

 

Average

D₁₀:         9.8 µm                                                              Standard deviation: 0.19 µm

D₅₀:         80.9 µm            (Median diameter)                      Standard deviation: 1.44 µm

D₉₀:         218.9 µm                                                           Standard deviation: 3.33 µm

Conclusions:

The D10, D50 and D90 percentile were determined as D10 = 9.8 µm, D50 = 80.9 µm and D90 = 218.9 µm, respectively.

Executive summary:

A study was conducted according to OECD Test Guideline 110 (1981) and ISO 13320 (2009). The D10, D50 and D90 percentile were determined by laser diffraction as D₁₀ = 9.8 µm, D₅₀ = 80.9 µm and D₉₀ = 218.9 µm, respectively.

Description of key information

The D10, D50 and D90 percentile were determined as D₁₀ = 9.8 µm, D₅₀ = 80.9 µm and D₉₀ = 218.9 µm (reference 4.5-1).
