Tapped Density and the Hausner Ratio
Tapped density testing settles a powder sample through repeated mechanical tapping to reach its most compacted volume, which, compared against the initial bulk volume, yields the compressibility index and Hausner ratio — standard indicators of a powder's flowability used in tablet and capsule formulation work. Running the test at both the USP 1 and USP 2 stroke settings allows results to be cross-checked against the pharmacopoeial method most relevant to a given product specification.
