NOTE 6Specific materials are: Your comments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend.

NOTE 7Because bulk factor is a dimensionless ratio, it permitsranking of plastic materials, with respect to volume change upon fabrica-tion, regardless of their molded or formed density or specific gravity.

Allow the weight to settle for 1 min and take the reading from the scale to the nearest 0.

Bulk Density

Privacy Statement Terms of Use. These test methods cover the measurement of apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders.

Densidad aparente y modulo de finura Documents. The bulk factor is also equal to the ratio of the density after molding or forming to the apparent density of the material as received. NOTE 7—Because bulk factor is a dimensionless ratio, it permits ranking of plastic materials, with respect to volume change upon fabrication, regardless of their molded or formed density or speci?

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.

Loosely drop 60 6 0. Xstm 96 Reapproved 1Standard Test Methods forApparent Density, Bulk Factor, and Pourability of PlasticMaterials1This standard is issued under the fixed designation D; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. Weigh the material in thecup to the nearest 0.

If caking occurs in the funnel, the materialmay be loosened with a small glass rod. Since these types of materials to be tested are very bulky when loosely poured and are usually compressed to lessen the bulk, a measure asrm their density zstm a small compression load is very useful. Measure the height ofthe loose d1985 in centimetres and identify this measurementas H1. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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. Preferred method of Contact: Make three determinations of the apparent density on each sample and average the results Note 2.

NOTE 2To convert grams per cubic centimetre to ounces per cubicinch, multiply by 0. If you feel that your comments have not received a fair hearing you shouldmake your views known to the ASTM Committee d189 Standards, at the address shown below. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the aboveaddress or at phonefaxor service astm.

Measure the height of the loose material in centimetres and identify this measurement as H1. Each test result was based on three individual determinations,and was obtained either by Test Method A or B, dependentupon equipment availability in the individual laboratory. This standard is also available to be included in Standards Subscriptions.

Also, since they ordinarily are very bulky when loosely poured and since they usually are compressible to a lesser bulk, even by hand, a measure of their density under a small load is appropriate and useful.

To convert grams per cubic centimetre to pounds per cubic foot,multiply by The total volume includes particle volume, inter-particle void volume and internal pore volume. While these powders usually will pour through this funnel, they may bridge in the cm3 cup shown in Fig.
