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:
- 1994
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 830.7520 (Particle Size, Fiber Length, and Diameter Distribution)
- Principles of method if other than guideline:
- At time of test performance, no guideline for testing of the particle size distribution of solids was established. The laser diffraction measurement is an established laboratory method for determination of particle size distribution of finely dispersed solids.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
