SUMMARY OF PARTICLE SIZE DATA
d(0.1) indicates the fraction of particles below the specified size, for example d(0.1) = 69.965 means that 10% of the particles are below 69.965µm. Similarly d(0.5) is 50% of particles below the given size and d(0.9) 90% of the particles.
PARTICLE SIZE DISTRIBUTION – FIRST SAMPLE
The smallest particle size observed was between 5.7 and 6.6µm, the largest particle size observed was between 1096.5 to 1258.9µm.
Applicant's summary and conclusion
- Conclusions:
- Very low proportion below inhalable fraction 10 u (< 0.5% by volume)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
