Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Data is from experimental study report
Qualifier:
according to
Guideline:
other: Seive analysis method
Principles of method if other than guideline:
The particle size distribution of test chemical was determined by measurement of relative amounts of particles present, sorted according to size.

Conclusions:
The particle size distribution of test chemical was determined by sieve analysis method. The particle size distribution was determined to be in the range of 250 micron to 53 micron. Majority of the particles were found to be in the size 250 micrometer (with 29.6% distribution) and 53 micrometer (with 27.5% distribution) in size.
Executive summary:

The particle size distribution of test chemical was determined by sieve analysis method. The particle size distribution was determined to be in the range of 250 micron to 53 micron. Majority of the particles were found to be in the size 250 micrometer (with 29.6% distribution) and 53 micrometer (with 27.5% distribution) in size.
