Evaluation of Automated Low-Field NMR Relaxometry For Analysis of Polymers
Screening studies and a Design of Experiment were performed to evaluate measurement variation of a new, non-destructive NMR test system designed to assess age induced degradation of Outer Pressure Pads. The test method and results from 76,746 measurements are described indicating that a metal support strut adjacent to the front position of the test chamber interferes with the measurements and that there is a measurement property gradient from the front to the back of the chamber. Also, obvious compression set areas on a surveillance OPP were not detected, but hidden, internal voids within a newly molded OPP were detected.
