Abstract :
The design and operation of a cyclic contact resistance test device for electromagnetic gasket materials is described. The device and associated instrumentation provide unique capabilities to measure electrical contact resistance for up to ten gasketed test assemblies as a function of make-and-break cyclic loading of the contacts. Resistance results for a custom gasketed contact design demonstrates that the test method is sensitive to both materials and lubrication used in the contact joint. The gasket cycler test system was designed and constructed to simulate the closure forces and mating action encountered by EMI gaskets in shielded facility access doors, hatchways, and cover panels
