The Cobb value of surface water absorption of paper and paperboard.:

The calculated mass of water absorbed in a specified time by a unit area of paper or board under specified pressure and temperature conditions. It is expressed in g/㎡.

C=(G2-G1)×100.

C-water absorptiveness

G2-wet mass, in grams, of the test piece

G1-dry mass, in grams, of the test piece
