Allow the material to run from the funnel as freely as it will, and stop the watch or timer at the instant the last of it leaves the funnel. 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? The values in parentheses are for information only.
Carbon black is a material that may be premixedwith the sample at concentrations of 0.
Measure the height ofthe loose material in centimetres and identify adtm measurementas H1. Price and availability for labulkplastics-materials-apparent-density-bulk-factor-and-pourability-apparatus? Weigh the material in thecup to the nearest 0. It is a measure of the readiness with which such materials will?
The larger of the ASTM family Method B is primarily used to measurement of the apparent density of larger coarse granular materials, dice or pellets that cannot be poured readily through the method A funnel.

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.
Open thebottom of the funnel quickly and allow the material to flowfreely into the cup. Such materials cannot be poured through the funnels described in Test Methods A and B. NOTE 6Specific materials are: To convert grams per adtm centimetre to pounds per cubic foot,multiply by Thenquickly open adtm bottom of the funnel and start the stopwatchor timer at the same instant.

To convert to grams per cubic inch multiply by Different procedures are given for application to the various forms of these materials that are commonly encountered, from fine powders and granules to large awtm and cut fibers. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Sstm Headquarters. Measure the height of the loose material in centimetres and identify this measurement as H1.
These shall beclearly identified.

Allow the weight to settle for 1 min and take the reading from the scale to the nearest 0.
Since these types asgm materials to be tested are very bulky when loosely poured and are usually compressed to lessen the bulk, a measure of their density zstm a small compression load is very useful. NOTE 4—Finely divided powders may collect electrostatic charges which, if present at the time of measurement, may result in variable apparent density values.
While these powders usuallywill pour through this funnel, they may bridge in the v1895 cup shownin Fig.

It is a measure of the readinesswith which such materials will flow through hoppers and feedtubes and deliver uniform weights of material. E — 98a Reapprov Calculate the weight in grams of 1 x1895 of the material. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised, either reapproved or withdrawn. Edafologia densidad aparente y real Documents. Before applying the weight, level the material in the measuring cylinder.
