The total volume includes particle volume, inter-particle void volume and internal pore volume.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Such materials cannot bepoured through the funnels described in Test Methods A and B.
Apparent Density Bulk Factor Pourability. It is a measure of the readiness with which such materials will? A bulk density tester does not measure an intrinsic property of a material; Bulk density can change depending on how the material is handled.
You can download and open this adtm to your asfm computer but DRM prevents opening this file on asttm computer, astk a networked server. While xstm powders usuallywill pour through this funnel, they may bridge in the cm3 cup shownin Fig. If the document is revised or amended, you will be notified by email.
These shall beclearly identified. Lower this weight gradually into the measuring cylinder untilit is entirely supported by the material. Lead shot is used to increase the 1d weight to g to compress the material under test. NOTE 4Finely divided powders may collect electrostatic chargeswhich, if present at the time of measurement, may result in variableapparent density values.
To convert to grams per cubic inch multiply by Carbon atsm is a material that may be premixed with the sample at concentrations of 0.
Densidad Aparente en El Satm Documents. We have no amendments or corrections for this standard. Insufficient data were collected for the evaluation of bulk factor and pourability because of the inherent properties of the tested materials, and limitations in the equipment available to the laboratories involved in the interlaboratory test.
It is a measure of the readinesswith which such materials will flow through hoppers and feedtubes and deliver uniform weights of material.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Make three d8195 of the apparent density on each sample and average the results Note 2. Bulk density is defined as the mass of many particles of the material divided by the total volume aetm occupy.
For example, a powder poured into a cylinder will have a particular bulk density; if the cylinder is disturbed, the powder particles will move and usually settle closer together, resulting in a higher bulk density.

Each of the materials were commercial materials and weredistributed to the testing laboratories on an as received bias. Your comments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend. Ifthe shape of the formed specimen is such that its volume maybe readily and accurately calculated from d8195 dimensions, thedensity may be determined by dividing the weight of thespecimen by its volume.

NOTE 2—To convert grams per cubic centimetre to ounces per cubic inch, multiply by 0. Already Subscribed to this document. C — 97 Reapprove Open thebottom of the funnel quickly and allow the material to flowfreely into the cup.
