This test method covers the determination of the quantity of water absorbed in a specified time by nonbibulous paper and paperboard with a minimum thickness of 0.1 mm. This test method is generally applicable to sized paper and paperboard, but is not recommended as a sizing test for writing papers. The test method is based upon studies by Cobb and Loew, Cobb, and other investigators.
Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, this test method was withdrawn in February 2010 because an equivalent TAPPI publication exists.
