Standard Specification for
Urethane Microcellular Shoe Soling Materials1
This standard is issued under the fixed designation D 3851; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers urethane microcellular materials for shoe soling applications. It provides properties and
dimensional requirements and test methods for specific properties.
1.2 SI units are to be regarded as the preferred units of
measurement for values. The inch-pound values in brackets
can be used if there is an agreement between the contractual
parties.
NOTE 1—There is no similar or equivalent ISO standard.
