Water absorptiveness (Cobb value) is the mass of water absorbed in a specific time by a 1 sq. meter sample of paper, board or corrugated under conditions specified in standards such as TAPPI T 441. Cobb sizing testers provide a simple, standardized method for fast determination of the quantity of water absorbed by a paper or board in a given time.
