Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03 July 2009 - 01 December 2009 -final repot 01 June 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Test method developed in testing laboratory and accuracy ratified against all standard tests.
- Qualifier:
- according to guideline
- Guideline:
- other: Standard Operating Procedure 060118.01 of Fraunhofer ITEM
- Principles of method if other than guideline:
- The standard procedure at Fraunhofer ITEM (direct method) was compared for some fibre samples to the line intercept method in previous studies. The resulting length weighted diameter distribution was not different between both methods
- GLP compliance:
- yes
- Type of method:
- determination of fibre length and diameter distributions
- Type of distribution:
- counted distribution
- Percentile:
- D50
- Remarks on result:
- other: Not a relevant descriptor for fibres as length contributes to mass but barely to aerodynamic diameter(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Conclusions:
- The products contain a very low proportion of nano particles/fibres . The arithmetic mean diameter is 1.5-4.0 microns
- Executive summary:
The material as sold consists of entangled fibres forming a wool. The length of these fibres is indeterminate and the product can be described entirely by the fibre diameter distribution, which is provided within this dossier.
