Water absorptiveness of sized (non-bibulous) paper, paperboard, and corrugated fiberboard (Cobb test)
|Publication Date:||1 January 2020|
This method describes a procedure for determining the quantity of water absorbed by nonbibulous paper, paperboard, and corrugated fiberboard in a specified time under standardized conditions. It is based on studies by Cobb and Lowe (1), Cobb (2) and other investigators (3, 4).
For testing unsized and absorbent paper or paperboard, see TAPPI T 432 "Water Absorbency of Bibulous Papers."
