Table No. 1 Results of determination of particle size distribution
Diameter on Cumulative 90%
Diameter on Cumulative 10%
The value nearest to average is used as final result of the test. That is the 1stmeasurement.
Detailed results of this measurement are stated at the Appendix 1.
Criteria of quality
The test satisfied quality criteria as follows:
The individual results of median from single testing should not vary more than 10 % from the average. For our measurements the calculated critical range is 15.74 to 19.24 µm.
We performed 6 measurements and the individual values fall within the range of quality criterion (actual range is 17.22 to 17.83).
The criterion of quality was met.
The determination of the particle size distribution of the test substance, Semi Dry Absorption (SDA) Product, was determined. The laser diffraction method was used.
Test was performed according to the standard ISO 13320-1 Particle size analysis – Laser diffraction methods – Part 1: General principles, First edition 1999-11-01.
The recommendations of Guidance Document on the Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances, EUR 20268 EN (2002) were considered.
Particle size distribution of the test substance Semi Dry Absorption (SDA) Product, is characterized by the following table:
The particle size distribution of the test substance was determined according to the standard ISO 13320-1 Particle size analysis – Laser diffraction methods.
Median: 17.43 um (ext. uncertainty 0.45)
