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 Thisspecification covers microcellular polyurethane materials for shoesoling applications. It provides physical property requirements andidentifies test methods for determining those specificproperties.
1.2 SIunits are to be regarded as the preferred units of measurements forvalues. The inch-pound values in parentheses can be used if thereis an agreement between the contractual parties.
Note1: There is no known ISO equivalentto this standard.
1.3This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
