1.1 This test method covers the determination of the time required for water to pass through a specimen of paper. It is based on the dry-indicator method of Carson (1-4) and modifications of it developed by Abrams (5)and Codwise (6-8).

1.2 It is designed for use with materials that require a relatively short time to test (up to approximately 30 s), and has been found useful in testing slack-sized papers.

Note 1—For testing hard-sized paper and paperboard, see TAPPI Test Method T 441.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
