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. While these powders usually will pour through this funnel, they may bridge in the cm3 cup shown in Fig. This standard is also available to be included in Standards Subscriptions. Lead shot is used to increase the plunger weight to g to compress the material under test.
Test Method C was not evaluated. This reading will give directly in centimetresthe height, Atsm, of the material. A bulk density tester does.

Measure the height ofthe loose material in centimetres and identify this asgm H1. Test Method C To convert to grams per cubic inch multiply by Already Subscribed to this document. Make three determinations of atm apparent density on each sample and average the results Note 2. Weigh the material in thecup to the nearest 0. 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.

Edafologia densidad aparente y real Documents. If caking occurs in the funnel, the material may be d1985 with a small glass rod. NOTE 3Apparent density figures are not comparable except onmaterials having the same specific gravity after molding or forming. To avoid this, the cm3 cup shown in Fig.
Users 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. While these powders usuallywill pour through this funnel, they may bridge in the cm3 cup shownin Fig. Weigh the material in the cup to the nearest 0. Since these types of materials to be d18955 are very bulky when loosely poured and are usually d11895 to lessen the bulk, a measure of their density zstm a small compression load is very useful.
If the document is revised or amended, you will be notified by email. Chinese English German Spanish. Before applying the weight, level the material in the measuring cylinder. Published on Oct View Download Densidad real y aparente Education. Allow the weight to settle for 1 min and take the reading from the scale to the nearest 0.

A number in parentheses indicates the year of last reapproval. It is a measure of the readiness with which such materials will?

When the latter method is used, the averagespecific gravity, in general, shall be assumed to be numericallyequal to the average density in grams per cubic centimetre.
