The cumulative percentage by weight of the test article collected at each successive stage was plotted by computer as a probability value against the logarithmic value of the upper class limit of that stage. The point at which the cumulative distribution line crossed the 50 percentile was the estimate of the mass aerodynamic diameter (MMAD). The Geometric Standard deviation was calculated.

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.
