【国外标准】 Standard Test Method for Resistance to Wetting of Garment-Type Leathers (Spray Test)

3.1 The procedure is intended primarily to evaluate garment-type leathers. The test method is qualitative and measures the surface-water repellency or surface-water resistance only. It is not intended for use in determining resistance to water penetration. A visual means is given to evaluate the relative effects of materials showing water repellency, but no comparison is possible with conditions found in actual use.1.1 This test method covers the qualitative evaluation of the surface repellency to water of garment-type leathers. 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 shown in parentheses are provided for information only.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.
