Results
Screening test (sieve method)
The results of the sieving procedure are shown in the following table:
Sieve aperture size (µm) |
100 |
Mass of test material transferred to sieve (g) |
15.36 |
Mass of test material passed through sieve (g) |
0.62 |
Test material less than sieve aperture size (%) |
4.04 |
Discussion
Due to the physical appearance of the test material, i.e. relatively large irregular-shaped clumps of aggregated material which do not break up easily, definitive testing was considered impractical.
Therefore, on review, the screening test result is considered to significantly overestimate the percentage less than 100 µm due to mechanical breakdown of these clumps during the 30 minute shaking period. A visual observation of the test material indicated very little fine material.
The inhalable fraction is defined as the mass fraction of particles which can be inhaled by nose or mouth.
Conclusion
The proportion of test material having an inhalable particle size less than 100µm was determined to be 4.04%.
Applicant's summary and conclusion
- Conclusions:
- The proportion of test material having an inhalable particle size less than 100µm was determined to be 4.04%.
- Executive summary:
For substance NDS-Li in project number 1307 -0447, the method used is designed to comply with that given in 'Particle Size Distribution, Fibre Length and Diameter Distribution', June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110. The proportion of test material having an inhalable particle size less than 100µm was determined to be 4.04%.
