Applicant's summary and conclusion
- Conclusions:
- The mass mean diameter of the particles of test item CA 2343 is 19.4 µm.
- Executive summary:
The purpose of this study was to evaluate the particle size distribution of test item cA 2343 (oxadiazinamine). The study followed a protocol similar to the OECD Guideline for Testing of Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter distributions", however the measuring procedure was based on the method of light diffraction. The mass mean diameter of the particles of test item CA 2343 is 19.4 µm.
