- Conclusions:
- The particle size distribution was determined using by a sieve screening technique. A fraction of 0.77% w/w was recorded as passing a 106 micrometer screen.
Particle size distribution (from NCD section 3.0.00):
From sieving analysis, < 1% of the substance by mass passed through a 106 µm sieve. Less than 10% by mass passed through a 300 µm sieve, with almost 70% being trapped in the 500 - 850 µm range.
Reference
Particle Size Distribution:
From sieving analysis,approximate distribution is:
< 1% > 2000µm
12% 850-2000µm
70% 500-850µm
10% 300-500µm
<10% <300µm
<1% < 106µm
Mass Median Diameter: Not determined by this method
Description of key information
Analysis was conducted by sieve method therefore mean particle diameter could not be determined. However, the bulk of the sample analysed had a particle size of between 2000μm and 300μm (appromately 90%), although the inhalable fraction is considered to be negligible. Further investigation of the particle size below 100μm is not considered to be necessary. In fact, less than 1% of the particles (by mass) are smaller than 106 μm.
