Water absorbance of paper or board with the Cobb method

This test measures the water absorption properties of paper and board. The method is not suitable for grades with grammage less than 50 g/m² or embossed paper. It is also unsuitable for highly water-absorbing papers, such as blotting papers.

The absorption time can be chosen by the customer. The result will be expressed as absorbed water per surface area (in g/m²).
