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:
- 2022-09-08
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
