Immersion Test

There is lot more to immersion testing than submerging waterproof enclosures under water per MIL STD 810. 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.

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. In one such test, NTS successfully operated a sheering mechanism designed to cut through bolts and cables on the ocean floor. NTS capabilities include hydro pressures to 50,000 psi (344,737 kPa). Combined immersion testing, vibration, ultrasonics, and temp cycling can be designed per your requirements. NTS can also design and develop aging tests for materials such as aluminum via high pressure and temperature in a condensate solution (water and pollutants).
