The wrong words are highlighted. Already Subscribed to this document. American society is strongly divided over the proposal for regulated, socialised health care funded from tax revenues and subject to control by elected representatives.
This standard is not included in any packages. For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number. If the document is revised or amended, you will be notified by email. The air-permeability technique is well established for measurement of the Specific Surface Area SSA of a sample powder.

By varying the sample height and porosity while controlling the flow rate of air through the sample, the SSA and average aztm size can be determined using the Kozeny-Carman equation.
The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.
