Electromagnetic Compatibility (EMC)


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.

Mechanical (Cycle) Aging


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.

Vibration Aging


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.

Seismic Triaxial and RIM Qualifications


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.

Radiation Aging and LOCA


Clark’s engineering services can help you determine the proper amount of radiation exposure required for your quali cation program or temperature and pressure pro le for LOCA screening based on equipment location.

Documentation


While physical testing is an important part of any quali cation program, even more crucial is proper documentation. Clark’s engineers are experienced with acceptable industry practices and standards to ensure your quali cation program is completely and comprehensively documented.

Engineering Services


Clark employs a professional staff of engineers qualified to assist you in the following areas:
  • Structural Design & Analysis
  • Mechanical Systems & Materials
  • Power Cycles / Thermodynamics
  • Licensed Professional Engineer Test / Design Certification



Clark Highlights

Accelerated Aging Image

Accelerated Aging

Clark’s accelerated aging and corrosion lab prepares products for the marketplace by subjecting them to harsh environmental conditions. Our NACE lab induces corrosion with hydrogen to accelerate the aging of metals. Clark’s salt spray chambers accommodate components being tested under MIL Standard 810. Clark has thermal chambers that simulate extremely hot, freezing and humid environments with thermal shock capabilities. Our HALT chambers provide mechanical testing while replicating environmental volatility.
