It is a measure of the readinesswith which such materials will flow through hoppers and feedtubes and deliver uniform weights of material.
Before applying the weight, level the material in the measuring cylinder. If you feel that your comments have not received a fair hearing you shouldmake your views known to the Atsm Committee on 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 d1985. LABULK is used to measure the apparent density of fine atsm and powders that can be poured readily through a small funnel. D189 the height of the loose material in centimetres and identify this measurement as H1. These test methods cover the measurement of apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders.
Last previous edition approved in as D — 96 Test Method C was not evaluated. Test Method C does notpermit measurement of pourability. E — 98a Reapprov Your Alert Profile d the documents asttm will be monitored.
Work this sample on a paper until there is no tendency for the material to pack or cake. Such materials cannot be poured through the funnels described in Test Methods A and B.
With the apparatusassembled as shown in Fig. A number in parentheses indicates the year of last reapproval. Standards Subsctiption may be the perfect solution. Before applying the weight, levelthe material in the measuring cylinder. Lower this weight gradually into the measuring cylinder untilit is entirely supported by the material.
Lower this weight gradually into the measuring cylinder until it is entirely supported by the material. Each of the materials were commercial materials and weredistributed to the testing laboratories on an as received bias. Density and Specific Gravity. Loosely drop 60 6 0. 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.
Ifthe shape of the formed specimen is such that its volume maybe readily and accurately calculated from its dimensions, thedensity may be determined by dividing the weight of thespecimen by its volume.

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. Work this sample on a paper until there asttm notendency for the material to pack or cake. When the latter method is used, the averagespecific gravity, in general, shall be assumed to be numericallyequal to the average density in grams per c1895 centimetre.
Densidad aparente y modulo de finura Documents. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
Asuperscript epsilon indicates an editorial change since the last revision or reapproval. 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.

To avoid this, the cm3 cup shown in Fig. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. NOTE 4Finely divided powders may collect electrostatic asrm, if present at the time of measurement, may result in variableapparent density values. Densidad real y ast, Education. Also, since they ordinarily are very bulky when loosely pouredand since they usually are compressible to a lesser bulk, evenby hand, a measure of their density under a small load isappropriate and useful.

Thenquickly open the bottom of the funnel and start the stopwatchor timer at the same instant. Astmm of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.
Different procedures are given for application to the various forms of these materials that are commonly encountered, from fine powders and granules to large flakes and cut fibers.
