Applicant's summary and conclusion
- Conclusions:
- Particle size data acquired for the test material are shown in the following table:
Measurement Method Result
Proportion of test material having an inhalable particle size less than 100 μm Sieve 61.0%
Proportion of test material having a thoracic particle size less than 10.2 μm Cascade impactor 4.24%
Proportion of test material having a respirable particle size less than 5.4 μm Cascade impactor 0.506% - Executive summary:
Particle size data have been acquired using a procedure designed to comply with the European Commision technical guidance document 'Particle Size Distribution, Fibre Length and Diameter Distribution' (June 1996), which satisifes the requirements of OECD Guideline 110. The results are as follows:
Measurement Method Result
