ASTM D 828 : 2022

1.1This test method covers procedures for determining tensile properties of paper and paperboard.

1.2The procedures given in this test method are for use with constant-rate-of-elongation tensile testing equipment and as such, are able to be used with instruments designed for either vertical or horizontal operation, and whether manually operated or computer controlled.

1.3These procedures are applicable for all types of paper, paperboard, paper products, and related materials within the measurement limitations of the equipment used. They are not for use with combined corrugated board.

1.4Properties able to be determined using this test method include tensile strength, stretch, tensile energy absorption, tensile stiffness, breaking length, and tensile index.

1.5The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
