This specification covers the standard physical property requirements and test methods for urethane microcellular materials intended for shoe soling applications. It covers three grades of polyurethane materials that may be selected for use according to abrasion resistance, cut-growth resistance, and other physical properties. Materials shall be subjected to physical tests and shall conform to the requirements for physical properties such as density, tensile strength, ultimate elongation, tear, hardness, cut-growth resistance, and taper abrasion or wear index.
1.1 This specification covers microcellular polyurethane materials for shoe soling applications. It provides physical property requirements and identifies test methods for determining those specific properties.
1.2 SI units are to be regarded as the preferred units of measurements for values. The inch-pound values in parentheses can be used if there is an agreement between the contractual parties.
Note 1: There is no known ISO equivalent to this standard.
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.
