(Test Method)Standard Test Method for Dynamic Water Resistance of Shoe Upper Leather by the Maeser Water Penetration Tester
Standard Test Method for Dynamic Water Resistance of Shoe Upper Leather by the Maeser Water Penetration Tester
SIGNIFICANCE AND USE
This test method is intended to estimate the water resistance of shoe upper leather. The flex imparted to the leather is similar to 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 D 2098.
SCOPE
1.1 This test method covers the determination of the dynamic water resistance of shoe upper leather by the Maeser water penetration tester. It is applicable to all types of shoe upper leather. Certain waterproof processes can cause contamination of the stainless steel balls. When this happens, visual inspection is recommended. This test method does not apply to wet blue.
1.2 Initial water penetration and water absorption can be measured by this test method.
1.3 This standard does not purport to address all of the safety problems 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.
