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 is not a good example for the translation above. When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration.

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. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned.

ASTM B – 02 Standard Test Method for Fisher Number of Metal Powders and Related Compounds

By varying the sample height and porosity while controlling aztm flow rate of air through the sample, the SSA and average particle size can be determined using the Kozeny-Carman equation. The Commission will inv ol v e society and m a ke societal im pa c t testing a n o bligatory part, where adtm, of all its future security research projects When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration.

These test methods shall not be used for mixtures of different powders, nor for powders astn binders or lubricants. The air-permeability technique is well established for measurement of the Specific Surface Area SSA of a sample powder.

The strategic importance of a sustainable supply of r a w materials t o ast he EU — for i t s indu st r y xstm 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.

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. Please first log in with a verified email before subscribing to alerts. This standard is also available to be included in Standards Subscriptions. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Your Alert Profile lists the documents that will be monitored. Thus, the results of these methods are only estimates of average particle size. Please first verify your email before subscribing to alerts.

In these cases, it is permissible to use the test methods described only by agreement between the parties concerned. Subscription pricing is determined by: The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes. For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number. One plot is based on results for inorganic mainly tungsten metal; the second on organic samples mostly pharmaceuticals.

Many applications use historical data and quality control standards, and a modern source of comparable, repeatable results is necessary.
