Significance and Use
5.1 Coating weight is an indicator of certain functional characteristics of coated substrates (for example, sealability, peelability, appearance). The methodology described in this practice is a means of determining coat weight.
5.4 This practice is applicable to coated substrates in which only the coating is soluble in the chosen solvent. The solvent used is critical to the success of the coating removal process. The coated substrate manufacturer must provide guidance in choice of solvent.
1.1 This practice covers a procedure for determining the amount of coating applied to a substrate, (for example, film, paper, nonwoven). The amount of coating is expressed as a weight per given area, (for example, g/m2, lb/ream).
