Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is marketed or used in a non solid or granular form
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to Column 2 of REACH Annex VII, section 7.14., the study to determine the granulometry of a substance does not need to be conducted if – among others – the substance is marketed or used in a granular form. The test item is an inorganic material that is manufactured from the underlying metal oxides by the Czochralski technique. The grown crystal (diameter: several centimeters) is then cut to smaller pieces in order to then be used for Scintillation applications. Based on the outlined particle size, conducting of the particle size distribution is considered as scientifically not necessary under REACH.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
