Abstract
Dry suits are worn by personnel from various civilian agencies for protection against exposure to water during immersion. Protection against chemical/biological contamination and insulation from cold water rely on the integrity of a suit's waterproofing. Dry suits may require test inspection to verify their integrity during both construction and actual use. While there are numerous standard leak test methods for fabric swatches, only a few exist for full suit systems. Literature review indicated testing of immersion suits is typically conducted by either filling the suit with water and inspecting its exterior for liquid breakthrough or by filling it with pressurized gas, rinsing its exterior with soapy water and inspecting for bubble formation. The report details an investigation into four alternative leak detection methods for dry suits.
