- Remarks on result:
- other: See below: any other information on results incl. tables
- Size:
- 12.5 other: mg/g
- Remarks on result:
- other: See below: any other information on results incl. tables
- Conclusions:
- The average dustiness of the sample was 12.5 mg/g i.e. 12.5 mg dust is generated per 1 g substance.
Referenceopen allclose all
Total dustiness: 12.5 mg/g
Dustiness is the proportion of dust arising from solid substances under processing, handling and transportation conditions, particularly the proportion of dus from powdered or granulated pigments and fillers.
Description of key information
Based on the total particle size testing and the dustiness testing, it can be confirmed that the substance has a low dustiness emission potential.
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.
