Principle:
Definition of tapped density is an increased bulk density attained after mechanically tapping a container containing the powder sample. Tapped density is obtained by mechanically tapping a graduated measuring cylinder or vessel containing a powder sample. After observing the initial powder volume or weight, the apparatus measuring cylinder or vessel is mechanically tapped, and volume or weight readings are taken until little further volume or weight change is observed. The mechanical tapping is achieved by raising the cylinder or vessel and allowing it to drop under its own weight a specified distance by either of three methods as during tapping may be preferred to minimize any possible separation of the mass during tapping down. This parameter is very important in packing the material. During tapping of the sample, the smaller particles try to fit themselves in gaps of the larger particles and hence the total volume of the powder reduces.

Frequently Asked Questions
1.    Measures of Compressibilty Index/Carr's Index and Hausner Ratio
-Because the interparticulate interactions influencing the bulking properties of a powder are also the interactions that interfere with powder flow, a comparison of the bulk and tapped densities can give a measure of the relative importance of these interactions in a given powder. Such a comparison is often used as an index of the ability of the powder to flow, for example the Compressibility Index/Carr's Index or the Hausner Ratio as described below.
The Compressibility Index/Carr's Index and Hausner Ratio are measures of the propensity of a powder to be compressed as described above. As such, they are measures of the powder's ability to settle, and they permit an assessment of the relative importantance of interparticulate interactions. In a free-flowing powder, such interactions are less significant, and the bulk and tapped densities will be closer in value. For poorer flowing materials, there are frequently greater interparticle interactions, and a greater difference between the bulk and tapped densities will be observed. These differences are reflected in the Compressibility Index/Carr's Index and the Hausner Ratio.
Compressibility Index/Carr's Index - Calculate by the formula:
100(V0-VF)/V0
V0=unsettled apparent volume
VF=final tapped volume
Hausner Ratio- V0/VF
2. EP 2.9.15 Apparent Volume - Mass requirement of a tap density tester?
-Into the dry cylinder,introduce without compacting 100.0 g (m g) of the substance to be examined.If this is not possible,select a test sample with an apparent volume between 50 ml and 250 ml and specify the mass in the expressing of results.
3. EP 2.9.15 Apparent Volume - Apparatus of a tap density tester?
-The apparatus consists of the following:1.a settling apparatus capable of producing in 1 minute 250+-15 taps from a height of 3+-0.2mm.The support for the graduated cylinder,with its holder, has a mass of 450 +- 5 g;2.a 250 ml graduated cylinder (2 ml intervals) with a mass of 220 +- 40 g.
4. EP 2.9.15 Apparent Volume-How to determine the apparent volume by a Tap Density Tester?
-The test for apparent volume is intended to determine under defined conditions the apparent volumes,before and after settling,the ability to settle and the apparent densities of divided solids for example,powders,granules.
5. How to determine the bulk density of a powder accroding to USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?
-The bulk density of a powder is determined by measuring the volume of a known weight of powder sample,that may have been passed through a sieve, into a graduated cylinder (Method I),or a measuring vessel (Method III).
6. Why how the determination is made is essential accroding to USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?
-The bulk density of a powder is often very difficult to measure with good reproducibility and ,in reporting the results,it is essential to specify how the determination was made.
7. What affect the bulk density accroding to USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?
-The bulking properties of a powder are dependent upon the preparation,treatment,and storage of the sample,i.e.how it was handled.The slightest disturbance of the powder bed may result in a changed bulk density.
8. How to express the bulk density according to international standard USP 616 Bulk Density and Tapped Density of Powders?
-The bulk density is expressed in grams per mL although the international unit is kilograms per cubic meter because the measurements are made using cylinders.It may also be expressed in grams per cubic centimeter.
9. What the bulk density depends on according to USP 616 Bulk Density and Tapped Density of Powders?
-The bulk density depends on both the density of powder particles and the spatial arrangement of particles in the powder bed.
10. What is the definiton of a bulk density according to USP 616 Bulk Density and Tapped Density of Powders?
-The bulk density of a powder is the ratio of the mass of an untapped powder sample and its volume including the contribution of the interparticulate void volume.
11. What are relation between USP 616 Bulk Density and Tapped Density of Powders and European Pharmacopoeia and Japanese Pharmacopoeia?
-USP 616 Bulk Density and Tapped Density of Powders has been harmonized with the corresponding texts of the European Pharmacopoeia and /or the Japanese Pharmacopoeia. The portion that is not harmonized is marked with symbols to specifiy this face.
12. What is the name of USP 616?
-USP 616 is Bulk Density and Tapped Density of Powders
13. What is test method 2 of international standard USP 616 Bulk Density and Tapped Density of Powders using a tap density tester?
-The method 2 is approximately same as method 1, operator proceeds as directed under Method I except that the mechanical tester provides a fixed drop of 3+-0.2 at a norminal rate of 250 taps per minute.
14. How to do if it is not possible to use a 100 g test sample during tap density testing using a tap density tester according to USP 616 Bulk Density and Tapped Density of Powders?
-Generally,replicate determination are desireable for the determination of this property. Specify the drop height with the results.If it is not possible to use a 100 g test sample, use a reduced amount and a suitable 100ml graduated cylinder (readable to 1ml) weighing 130+-16g and mounted on a holder weighing 240+-12g. The modified test conditions are specified in the expression of the results.
15. What is the test procedure in USP 616 Bullk Density and Tapped Density of Powders method 1 using a tap density tester?
-Proceed as described in USP 616 for the determination of the bulk volume.Secure the cylinder in the holder. Carry out 10,500, and 1250 taps on the same powder sample and read the corresponding volumes V10,V500 and V1250 to the nearest graduated unit. If the difference between V500 and V1250 is less than or equal to 2ml,V1250 is the tapped volume.If the difference between V500 and V1250 exceeds 2ml,repeat in increments such as 1250 taps,until the difference between succeeding measurements is less than or equal to 2ml.Fewer taps may be appropriate for some powders, when validated. Calculate the tapped density using the relevant formula in USP 616 to calculate the final tapped volume and therefore calculate the final tapped density.
