ASTM D 2209:2025

1.1 This test method covers the determination of the load required to rupture a leather test specimen having a ¹/₂ in. (12.7 mm) width. The load to rupture divided by the original unstretched cross-sectional area gives the tensile strength. It may be used for all types of leather that are smooth and firm enough to permit accurate thickness measurements. This test method does not apply to wet blue. 1.2 This test method also covers the measurement of the elongation or stretch characteristics of leather produced by a tensile load. This test method is intended for use on all types of leather and with all breaking load tests. This test method does not apply to wet blue. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This 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.
