(Test Method)Standard Test Method for Static Water Absorption of Leather
Standard Test Method for Static Water Absorption of Leather
SIGNIFICANCE AND USE
5.1 This test method is used to determine compliance with specifications for water absorption of upper leather. The significance of the test method is limited by the static conditions employed, and the results do not reflect the water absorption under dynamic conditions of flexing.
SCOPE
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. This test method does not apply to wet blue.
1.2 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.
1.3 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.
