- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2019-03-04 to 2019-05-14
- 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) - Method B: Fibre Length and Diameter Distributions
- Principles of method if other than guideline:
- - Principle of test:
laser diffraction method
- Short description of test conditions: The particle size is measured by laser diffraction. The Sympatec HELOS KF determines the diffraction pattern of a laser light beam. The sample is dropped through parallel beam laser beam setup by dropping it from a dispersing unit with Sympatec VIBRI vibrating rail and pneumatic conduction with a pressure of 3.00 bar. An optical concentration of 7.53% was measured within the detector cell.
The particles pass through the laser beam. Depending on their size, diffraction takes place. A smaller particle size leads to a wide diffraction pattern, while large particles give a smaller diffraction. The laser’s diffraction pattern is detected within the device, and is used to calculate the particle size distribution. - GLP compliance:
