Abstract
A fixture assembly and inspection method by which the internal diameter and/or concentricity of a segmented annular seal can be readily inspected and optionally measured prior to final installation. The fixture assembly has at least two fixture segments supported on a base, by which an annular fixture housing is defined having an outer rim and a groove with a cross-sectional shape corresponding to a cross-sectional shape of the annular seal. The fixture assembly further includes a device or apparatus for assessing at least one dimensional characteristic of the annular seal when installed in the groove of the fixture housing and as the assessing device/apparatus travels along the interior circumference of the fixture housing.
