Your Alert Profile lists the documents that will be monitored. Thus, the results of these methods are only estimates of average qstm size. This standard is also available to be included in Standards Subscriptions. The wrong words are highlighted. These test methods shall not be used for mixtures of different powders, nor for powders containing binders or lubricants.

The graphs above compare the mean particle size data from the two instruments on powders of different sizes. When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration. The strategic importance of a sustainable supply of r a w materials t o t he EU — for i t s indu st r y and society a s a whole — has been well recognised in different strategic policy documents such as the Raw Materials Initiative1 proposed by the European Commission, related Council Conclusions2 and Report from the EP3.

It b303 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.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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 satm and quality control standards, and a modern source of comparable, repeatable results is necessary. What is Air-permeability Particle Sizing? By varying the sample height and porosity while controlling the flow rate of air through the sample, the SSA and average particle size can be determined using the Kozeny-Carman equation.

The SAS utilizes dual pressure transducers to measure pressure drop across a packed bed of powder. The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.

When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned. One plot is based on results for inorganic mainly tungsten metal; the second on organic samples mostly pharmaceuticals.

The SSA measured by this technique has been found to be a useful parameter in various industries such as pharmaceutical, metal coatings, paints, and even geological samples. If the document is revised or amended, you will be notified by email. It does not match my search.

For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number. The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.
