Water resistance of sized paper and paperboard (dry indicator method)
This method is based on the dry-indicator method of Carson (1-4) and modifications of it developed by Abrams (5) and Codwise (6-8). It is designed for use with materials that require a relatively short time to test (up to about 30 s) and has been found useful in testing slack-sized papers. For testing hard-sized paper and paperboard, see TAPPI T 441 "Water Absorptiveness of Sized (Non-bibulous Paper and Paperboard (Cobb Test)"; for testing unsized and absorbent paper, see TAPPI T 432 "Water Absorbency of Bibulous Paper."
