This British Standard describes a method for determining the absorption of water by paper and board. The method is applicable to all paper and board with medium or high water absorbency where the wetting of the material can be detected visually.

The method is not recommended for materials having a capillary rise of less than 5 mm, for which other methods, such as BS 2644, may be more suitable.

NOTE. The titles of the publications referred to in this standard are listed on the inside back page.

Describes a method of determining the water absorption of paper and board using a closed vessel to provide a saturated atmosphere. The method provides better accuracy than the open vessel method in BS 2916.
