materialized_physical_object

A <materialized_physical_object> is a <physical_object> that has matter and/or energy continuity as its basis for identity. Matter or energy continuity requires some matter or energy to be common to adjacent temporal parts of the <materialized_physical_object>. Replacement of some components from time to time does not create a new identity.
EXAMPLE The shell and tube heat exchanger with manufacturer's serial number ES/1234 can be represented by an instance of <materialized_physical_object>.
