Medias this blog was made to help people to easily download or read PDF files. The total volume includes particle volume, inter-particle void volume and internal pore volume. Insufficient data were collectedfor the evaluation of bulk factor and pourability because of theinherent properties of the tested materials, and limitations inthe equipment available to the laboratories involved in theinterlaboratory test.

S1895 reading will give directly in centimetresthe height, H2, of the material. 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.
This edition includes the addition of an extensive ISO equivalency statement andkeywords section.

Allow the weight tosettle for 1 min and take the reading from the scale to thenearest 0. E — 98a Reapprov Please enter the letters from the image: Such materials cannot bepoured through the funnels described in Test Methods A and B. These test methods cover the measurement of apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders. This standard has been approved for use by agencies of the Department of Defense.
Work this sample on a paper until there is notendency for the material to pack or cake. We have no amendments or corrections for this standard.

Your comments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend. To avoid this, the cm3 cup shown in Fig. Please first log in with a verified email before subscribing to alerts.
The weight per unit volume of a material, including voids inherent in the material as tested is apparent density. This standard is also available to be included in Standards Subscriptions.
Different procedures are given for application to the various forms of these materials that are commonly encountered, from?

Specifications Measuring funnel Weight plunger Lead shot Tests that can be conducted are: 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. Make three determinations of the apparent density on each sample and average the results Note 2. With the apparatus assembled as shown in Fig.
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.
TestMethod C was not evaluated. The values in parentheses are for information only. Allow the material to run from the funnel as freely as it will, and stop the watch or timer at qstm instant the last of it leaves the funnel.
Different procedures are given for application to the various aztm of these materials that are commonly encountered, from fine powders and asrm to large flakes and cut fibers. Last previous edition approved in as D 96 If you feel that your comments have not received a fair hearing you shouldmake your views known to the ASTM Committee on Standards, at the address shown below.
Already Subscribed to this document. Before applying the weight, level the material in the measuring cylinder. The larger of the ASTM family Method B is primarily e to measurement of the apparent density of larger coarse granular materials, dice or pellets that cannot be poured readily through the method A funnel. For coarse flakes, strands, chips and cut fibres that cannot be poured using test methods A and B Ray-Ran offer a measuring cylinder and plunger to method C of the ASTM test standard.
