【国外标准】 Standard Test Method for Dynamic Water Resistance of Shoe Upper Leather by the Dow Corning Leather Tester

3.1 This test method is intended to estimate the water resistance of shoe upper leather. The flex imparted to the leather is a magnification of the flex given the vamp of the shoe in actual wear.NOTE 1: There is an indication that this test method cannot be used interchangeably for specification purposes with Test Method D2099.1.1 This test method covers the determination of the dynamic water resistance of shoe upper leather by means of the Dow Corning Tester. It is applicable to all types of shoe upper leather. This test method does not apply to wet blue or wet white.1.2 Initial water penetration and water absorption can be measured.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.
