Administrative data

Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The tested samples were crushed prior to testing. Therefore the result of the test should be used with caution and hence the reliability code assigned.

Applicant's summary and conclusion

Conclusions:
Two samples were tested, 10TT03302 and sample 10TT00905, with respectively D50 < 20 micrometer and D50 = 39 micrometer. Nevertheless the result of the test should be used with caution since the tested samples were crushed prior to testing.
