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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
