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. What is Air-permeability Particle Sizing? Your Alert Profile lists the documents that will be monitored. Wstm 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.

American society is strongly divided over the proposal for regulated, socialised health care funded from tax revenues and subject to control by elected representatives. For this reason, values obtained by these test methods will be reported as an average particle size astn Fisher Number.

There is exceptional correlation between the two sets of data. Link to Active This link will always route to the current Active version of the standard. 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.

The air-permeability technique is well established for measurement of the Specific Surface Area SSA of a sample powder.

This is not a good example for the translation above.

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. In these cases, it is permissible to use the test methods described only by agreement between the parties concerned. The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

The strategic importance of a sustainable supply of r a w materials v330 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 Atm Initiative1 proposed by the European Commission, related Council Conclusions2 and Report from the EP3.

The SAS utilizes dual pressure transducers to measure pressure drop across a packed bed of powder. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. This standard is not included in any packages.

The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes. 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. Methods of de-agglomeration such as that specified in Practice B may be used if agreed upon between the parties concerned.

This standard is also available to be included in Standards Subscriptions. 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. When the powder contains agglomerates, the measured surface area may be affected by the degree of agglomeration.
