ABSTRACT:
A method and apparatus for rapidly determining the cure state of an annular rubber or elastomeric article is provided. The article is placed so that an inner hole portion fits over separable parts of a test fixture, and tension is induced in a stepwise manner by moving the separable parts apart in discrete incremental steps. The tension is allowed to relax between the steps. By generating a force/deflection curve in this way, the user may optimize the cure state of the tested articles by controlling the cure time and temperature of a manufacturing process in response to the measured data.
