Common to automated systems and electronics in the industry is the requirement to ensure electromagnetic compatibility of components and mitigate vulnerability to outside sources. Emissions and Immunity analysis provides insight as to the potentially undesirable propagation and reception of electromagnetic energy and radiofrequency interference. Clark’s EMC lab is ISO 17025 accredited and enveloped under the 10 CFR 50 Appendix B program maintained by Clark Dynamics.

Unique to each test specimen are its functional and design-basis lifetime requirements. Clark’s facilities have the equipment and technical expertise to test a variety of components for mechanical fatigue and failure, life cycle, aging, accelerated aging, and simulation that is common to the power generation industry. Common test specimens include valves, pumps and actuators.

Often prior to seismic quali cation is the accelerated dynamic aging (simulated life-span) of a test specimen in its eld-mounted orientation. Sinusoidal sweeps determine the test specimen’s most vulnerable resonant frequency at low acceleration levels, and subsequent dwell periods age the equipment at a given frequency and/or higher acceleration level prior to seismic exposure.

Clark’s triaxial shake table provides simultaneous motion in the three orthogonal directions for the testing of structurally-mounted equipment (ground or wall-mounted). Our required input motion (RIM) uniaxial table tests equipment used in line-mount- ed applications to ensure that it will withstand the potentially harsh dynamic conditions encountered during a seismic event, a high-energy line break, or from resonance induced pipe rupture.
