Conclusions:
The test itme p-phenylene diisocyanate has a coarse fraction > 2000 um of 22.1 wt.-%. The fine fraction has a median particle size of D50=408 um, which was determined by laser diffraction measurment according to OECD Test Guideline 110 (1981) and ISO 13320 (2009).
Executive summary:

The test itme p-phenylene diisocyanate has a coarse fraction > 2000 um of 22.1 wt.-%. The fine fraction has a median particle size of D50=408 um, which was determined by laser diffraction measurment according to OECD Test Guideline 110 (1981) and ISO 13320 (2009).
