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.

Distribution of crushing strength of tablets ScienceDirect

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

The Lubricant film interfere with the bonding properties of host particle by acting as a physical barrier. This can be seen when the Tablet crushing strength is plotted as a function of the Log of the mixing time with the Lubricant.

BP Testing (Solid Dosage Forms) Flashcards by Em A

Crushing strength can be measured with different units Kilogram(kg)–The kilogramme is recognised by the SI system as the primary unit of mass. Newton(N)–The Newton is the SI unit of force and is the unit that should be used for tablet hardness testing. 9.807 Newtons = 1 kilogram.
