Conclusions:
The particle size distribution of the test item N,N-Bis(2-hydroxyethyl)-p-phenylenediamine sulphate monohydrate was determined according to DIN 66165, April 1987. The mean particle diameter was calculated to be 140.5 um (>0 - <1400um).
Executive summary:

The particle size distribution of the test item N,N-Bis(2-hydroxyethyl)-p-phenylenediamine sulphate monohydrate was determined according to DIN 66165, April 1987. The sieve analysis was carried out by the dry sieving technique using analytical sieves with mesh sizes 63, 125, 250, 500, 1000 and 1400um. The mean particle diameter was calculated to be 140.5 um (>0 - <1400um).
