Description of key information

Determination of the particle size.

Additional information

A key study was performed to determine the particle size distribution of FAT 40554 according to the test method described in DIN 53734.

The percentage of test item with an particle size <10 µm (sieve method) was 0 %.

The percentage of test item with a particle size <45 µm (sieve method) was 20.8 %.

The percentage of test item with a particle size <75 µm (sieve method) was 35.3 %.

 

The percentage of test item with an particle size <250 µm (sieve method) was 51.7 %.

The percentage of test item with a particle size <425 µm (sieve method) was 67.4 %.

The percentage of test item with a particle size <600 µm (sieve method) was 76.4 %.

 

The percentage of test item with a particle size <850 µm (sieve method) was 85.4 %.
