5.1 This test method is currently used to determine compliance with specifications for water absorption of impregnated sole leather. The significance of the test method is limited by the static conditions employed, and the results do not reflect the water absorption under the dynamic conditions of flexing. The result may be corrected, if required, for any water-soluble material removed from the leather during the test.

1.1 This test method covers the determination of the amount of water absorbed by leather at 23 ± 2 °C by immersion under static conditions. It may be used on all types of leather, but is particularly adapted to vegetable-tanned sole leather. This test method does not apply to wet blue.

1.2 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.

1.3 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.
