- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- ISO 13320:2009 Particle size analysis - Laser diffraction methods
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Deviations:

- St. dev.:
- 1
- Remarks on result:
- other: "According to ISO 13320 the relative standard deviation for d50 is smaller than 3 %, for d10 and d90 smaller than 5 %. For powders below 10 µm these maximum values should be doubled."
- Percentile:
- D50
- Mean:
- 38.6 µm
- St. dev.:
- 1.2
- Remarks on result:
- other: "According to ISO 13320 the relative standard deviation for d50 is smaller than 3 %, for d10 and d90 smaller than 5 %. For powders below 10 µm these maximum values should be doubled."
- Percentile:
- D90
- Mean:
- 67 µm
- St. dev.:
- 3.4
- Remarks on result:
- other: "According to ISO 13320 the relative standard deviation for d50 is smaller than 3 %, for d10 and d90 smaller than 5 %. For powders below 10 µm these maximum values should be doubled."
- Conclusions:
- The mass median aerodynamic diameter of the test material dimanganese trioxide is 38.6 µm.
- Executive summary:
The granulometric properties of dimanganese trioxide were analysed by laser diffraction method according to ISO 13320-2009. Therefore, a sample of the test substance dimanganese trioxide was dispersed in water and Fraunhofer approximation was used for calculation of particle size distribution (PSD). The results of the PSD for dimanganese trioxide was as follows:
D (v, 0.1) = 20.4 μm
D (v, 0.5) = 38.6 μm
D (v, 0.9) = 67.0 μm.

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.
