As the voice of the U. The SAS utilizes dual pressure transducers to measure pressure drop across a packed bed of powder.

ASTM B330 – 15

Many applications use historical data and quality control standards, and a modern source of comparable, repeatable results is necessary. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If the document is revised or amended, you will be notified by email.

Already Subscribed to this document. 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 air-permeability technique is well established for measurement of the Specific Surface Area SSA of a sample powder. The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes. Proceed to Checkout Continue Shopping. 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.

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.

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 b330.

This is a crucial point, as the air permeability technique and the FSSS have been used as a benchmark for decades in many industries. 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.

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. 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.
