Description of key information

Determination of the particle size distribution of FAT 65088/A TE.

Additional information

The method used a procedure designed to be compatible with European Commission Technical Guidance Document EUR 20268 ‘Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of chemical substances’ (2002).


Particle size data acquired for the test item is shown in the following table:

 Measurment  Method  Results
 Proportion of test item having an inhable particle size < 100 micrometer  Sieve  70.8 %
 Proportion of test item having a thoracic particle size < 10.0 micrometer  Cascade impactor  <= 4.77 %
 Proportion of test item having a respirable particle size < 5.5 micrometer  Cascade impactor  <= 0.2520%
