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.
