Definition

mass density of a particulate material that is the mass per tapped volume occupied by the material after tapping until little or no further volume change is observed

Examples

• the tapped density of powdered cell culture medium measured during raw material characterization; the tapped density of a specific grade of granular PVC resin measured with a tap density tester to characterize a product lot; the tapped density of an excipient powder used in tablet formulation development;

Synonyms

• tap density

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs for creating a set of necessary and sufficient conditions.

Formal Axioms

First-Order Logic Axioms

TappedDensity(x) → MassDensity(x) ∧ ∃m (MaterialEntity(m) ∧ qualityOf(x, m) ∧ ∃f (ParticulateForm(f) ∧ hasQuality(m, f)))

Semi-Formal Natural Language Axioms

if x is a ‘tapped density’ then x is a ‘mass density’ that is the ‘quality of’ some ‘material entity’ that ‘has quality’ some ‘particulate form’
