Particle size distribution (Granulometry)

Currently viewing:

Administrative data

Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Lacking of statistical data on testing accuracy. Only double sample. Otherwise a well performed test in a laboratory with GLP compliance.
