This standard is also available to be included in Standards Subscriptions. This standard is not included in any packages.
We have no amendments or corrections for this standard. For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. In these cases, it is permissible to use the test methods described only by agreement between the parties concerned.
One plot is based on results for inorganic mainly tungsten metal; the second on organic samples mostly pharmaceuticals. When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration. You may delete a document from your Alert Profile at any time.
The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes. The degree of correlation between the results of these test methods and the quality of powders in use will vary with each particular application and has not been fully determined.
The SSA measured by this h330 has been found to be a useful parameter in various industries such as pharmaceutical, metal coatings, paints, and even geological samples. Most frequent English dictionary requests: This is a crucial point, as the air permeability technique and the FSSS have been used as a benchmark for decades in many industries. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned.

It should not be summed up with the orange entries The translation is wrong or of bad quality. They should not be used for powders composed of particles whose shape is too far from equiaxed – that is, flakes or fibers. Many applications use historical data and quality control standards, and a modern source of comparable, repeatable results is necessary.
