Clause 7.3 addresses the representation of strength concentration. Strength is not a number on its own: it needs a numerator, a unit, a denominator or a presentation basis, and a convention for expressing a range, a ratio or a quantity per unit. The clause sits after cardinality and before the identifier clause, which reflects the dependency: the identifier cannot be built until the strength can be compared. The clause is also the bridge to clause 7.7, which deals with the attributes used to express strength in the identifier elements. The public contents give the title but not the body. The exact representation rules, including the treatment of units and the permitted denominators, are not stated in the text we hold. The public FDA material on the IDMP family confirms that units of measurement are governed by a companion standard and that strength is one of the elements used to build the identifier.
