Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Particle size distribution (Granulometry)
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:
- 2015-05-11
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 13320-1
- Principles of method if other than guideline:
- Laser diffraction method - The test was conducted according to the guidance of the apparatus used. A short description is given below:
The dry test substance is dispersed and passes a laser in form of an aerosol. In dependence on the particle size the laser is diffracted. The resulting so called “Fraunhofer” diffraction spectrum is bundled using a converging lens in a multi-element photo detector. In dependence of the particle size distribution a radial symmetric intensity distribution is generated. The measured intensity is analysed by a computer and converted into a particle size distribution. - GLP compliance:
- not specified
- Type of method:

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.
