Immersion Testing

NTS provides every type of immersion test possible, including corrosive materials, detergents, heated liquids or tests for functional performance of mechanical and hydraulic components under high pressure. Our capabilities include hydro pressures to 50,000 psi. Combined immersion testing programs, integrating additional elements such as vibration, ultrasonics and temperature cycling can also be designed per your requirements. NTS can also design and develop specialized aging tests for materials such as aluminum via high pressure and temperature in a condensate solution (water and pollutants).

There is lot more to immersion testing than just submerging waterproof enclosures under water per the specifications of various regulatory standards. In fact, immersion testing applies to research as diverse as the uptake of water in fiber-optic bonds to the susceptibility of stainless steels to intergranular corrosion when boiled in sulfuric acid. Immersion testing means serious business when transportation of hazardous materials is involved. International and U.S. Safety Standards for plutonium air shipments call for a minimum of immersion under at least 3 ft (0.9m) of water for at least 8 hours. The NRC requires equivalent length under at least 50 ft (15m) of water. Transportation of anthrax-contaminated material requires both watertight primary and secondary receptacles. With a new Nevada nuclear waste site soon to be functional and vaccinations against anthrax a nationwide reality, container makers must develop consistently leak-proof packaging for transport.
