- Conclusions:
- The particle size distribution was determined as percentage distribution of test chemical in various sieves. the particle size distribution was determined to be in the range of 150 micron to 53 micron.
- Executive summary:
A study was performed to determine the particle size distribution of test chemical within range of 150 µ to 10 µ. The study was conducted in accordance with OECD guideline 110 and according to method adapted from ASTM B214-99.” The particle size distribution was determined to be in the range of 150 micron to 53 micron.
