- Conclusions:
- The test material dimtehylamine-borane (1:1) has a mass median aerodynamic diameter (D50 value) of 656 µm.
- Executive summary:
The test item dimethylamine-borane has a coarse fraction > 2000 μrn of 37 wt.-%. The fine fraction has a median particle size D50 = 656 μm, which was determined by laser diffraction measurement in accordance to inter alia ISO 13320 (2009) and CIPAC MT 187 (2009) method. D10 and D90 of the fine fraction are 262 µm and 1223 µm, respectively.

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.
