Witryna9.4.2 Leak test. The leak test is performed by immersing a part, usually a sandwich composite structure, in a hot water tank. The temperature of the water induces the expansion of air in the structure, and if a crack or a delamination is present, gas bubbles escape the structure and are immediately detected by visual inspection. WitrynaFor leaks of air into the atmosphere, units are expressed as mm 3 or cm 3 (cc) per second or minute. So 16.6 mm 3 /sec = 1 cm 3 /min. A bubble under water is about 30-50 mm 3, so 1 bubble per second is about 30 mm 3 /sec or 2 cm 3 /min. A standard unit of leakage which takes account of air pressure is the mbarl/sec (millibar-litre per second). poor little bear painting
