For beams requiring 48 mils, what is the minimum permissible average TFIFRM thickness?

In fireproofing, the thickness requirement is a minimum that must be met or exceeded. For a beam that requires 48 mils, the minimum permissible average TFIFRM thickness is the full specified thickness, expressed as 100%. So you must average at least 48 mils; anything less would not meet the spec, while thicker coatings are allowed but exceed the minimum.
