    Abstract: A test instrument for determining processing and manufacturing uniformity in molded elastomeric articles such as O-rings wherein the O-ring is flexed between two power driven rollers while being loaded at a predetermined deflection by a third roller connected to a load-sensing element. The output of the sensing element is directed to an instrumentation device which records the stress level about the circumference of the O-ring the output variations being indications of internal discontinuities and manufacturing defects in the tested article.
