ISO 535 COBB absorption tester is for the measurement of surface water absorption of paper and paper board. Loose paper, e.g. newsprint, unsized paper, e.g. blotter and other high absorbability paper is not for this tester.
ISO 535 COBB Absorption Tester Principle
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
When Cobb value is less than 200～250 g/㎡ for single layer, more layers can used.
