Title
Standard Test Method for Internal Tearing Resistance of Paper

ASTM International

Publication Date:
Apr 10, 2003

Scope:

This test method measures the force perpendicular to the plane of the paper required to tear multiple sheets of paper through a specified distance after the tear has been started, using an Elmendorf-type tearing tester. The measured results can be used to calculate the approximate tearing resistance of a single sheet. In the case of tearing a single sheet of paper, the tearing resistance is measured directly.

NOTE 1 - Similar procedures for making Elmendorf-type tear measurements are found in ISO 1974 and TAPPI T414.

This test method is not suitable for determining the cross-directional tearing resistance of highly directional boards and papers.

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.
