One plot is based on results for inorganic mainly tungsten metal; the second on organic samples mostly pharmaceuticals. The graphs above compare the mean particle size data from the two instruments on powders of different sizes. This is not a good example for the translation above. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned.

Need more than one copy? Thus, the results of these methods are only estimates of average awtm size. The values obtained are not intended to be absolute but are b30 useful on a relative basis for control purposes. Numerous extensive studies have come to the same conclusion.

This standard is also available to be included in Standards Subscriptions. It should not be summed up with the orange entries The translation is wrong or of bad quality. This is a crucial point, as the air permeability technique and the FSSS have been used as a benchmark for decades in many industries.

For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number. 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 h330 has been well recognised in different strategic policy documents such as the Raw Materials Initiative1 proposed by ashm European Commission, related Council Conclusions2 and Report from the EP3.

Standards Subsctiption may be the perfect solution.

These test methods shall not be used for mixtures of different powders, nor for powders containing binders or lubricants. They should not be used for powders composed of particles whose shape is too far from equiaxed – that is, flakes or fibers.

It is the aastm of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration. You helped to increase the quality of our service.

These test methods shall not be used for mixtures of different powders, nor for powders containing binders or lubricants. As the voice of the U. By varying the sample height and porosity while adtm the flow rate of air through the sample, the SSA and average particle size can be determined using the Kozeny-Carman equation.

Historical Version s – view previous versions of standard Translated Version s: The degree of correlation between the axtm of these test methods and the quality of powders in use will vary with each particular application and has not been fully determined. 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.

Standards Subscriptions from G330 provides a money-saving, multi-user solution for accessing standards. Link to Active This link will always route to the current Active version of the standard. There is exceptional correlation between the two sets of data.

Many applications use historical data adtm quality control standards, and a modern source of comparable, repeatable results is necessary. Subscription pricing is determined by: Already Subscribed to this document. 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. The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.

Your Alert Profile lists the documents that will be monitored. For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number. Porous nickel metal produced from materials specified in 1C In these cases, it is permissible to use the test methods described only by agreement between the parties concerned.

The air-permeability technique is well established for measurement of the Specific Surface Area SSA of a sample powder. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned.

American society is strongly divided over the proposal for regulated, socialised health care funded from tax revenues and subject to control by elected representatives. Thus, the results of these methods are only estimates of average particle size.

When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration. If the document is revised or amended, you will be notified by email. Support activities would be meant as an incentive to speed up cooperation and the use of information and communications technologies for geographically dispersed facilities leading to improve transfer and exploitation of results, in partic ul a r for S M Esin the fiel d o f materialsp ro duction technolog ie sand m e as ure me n t and testing.
