ASTM D829-97(2002) (R1997)

1.1 These test methods measure the (wet) tensile breaking strength of paper, paper products, and paperboard (excluding corrugated board) when saturated with water.

1.2 These test methods are intended for use with papers and paper products that will be subjected to stress while wet during processing or use, including but not limited to tissue products, papers used in map-making, photography and blue prints, bags, and food wraps.

1.3 Two test methods are described; one for samples that are able to be handled while wet without damage, and one for samples, such as tissue, that are easily damaged or impossible to handle while wet.

1.4 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.

Wet tensile strength is an important performance characteristic of papers or paper products that will be processed wet or that may be subjected to wetting, whether accidental or intentional, during use.
