  1. In this method ( 1-3 ) , the contact angle between air and liquid on a paper surface is taken as a measure of the resistance of the paper surface to wetting by the liquid.
  2. The ruling and writing qualities of paper are of importance for papers intended for drafting and writing. These papers must accept ink (ruling quality) without feathering (writing quality) . Certain ranges of contact angle are reportedly indicative of these qualities.
  3. The range of contact angles for specific conditions is small; consequently, careful testing technique is required as is indicated by the above examples.
  4. Sample the paper in accordance with TAPPI T 400 “Sampling and Accepting a Single Lot of Paper, Paperboard, Containerboard , or Related Product .” Be careful not to touch the areas to be tested, or contaminate them in any other way.
