Distribution of crushing strength of tablets

2002-5-1 · The statistical distribution of tablet crushing strength or tensile strength is important since parametric inference tests like the t-test, F-test, analysis of variance and regression analysis require normal distribution of the random variable. The primary aim of this investigation is therefore to investigate whether the normal distribution is representative for a random sample of tablet crushing strength data

Crushing strength, disintegration time and weight

1997-6-1 · Tablets with a crushing strength of over 300 N are rarely needed, however. In order to produce strong tablets, the powder particles have to be packed densely, close to each other. In these experimental tabletting conditions the maximum bonding between the Avicel® PH particles was achieved with mixtures where the proportion of small, fibrous particles was high.

2008-8-6 · For measuring the crushing strength of the tablets, Raman spectra were recorded from the tablets. Partial least squares (PLS) regression models were constructed to obtain information from the spectra. The correlation between measured and predicted crushing strength values for the tablets was shown to be very favorable.

<1217> TABLET BREAKING FORCE

The term crushing strength is also frequently used to describe the resistance of tablets to the application of a compressive load. Although this term describes the true nature of the test more accurately than does hardness, it implies that tablets are actually crushed during the test, which often is not the case.
