Which Units are Used in Leak Testing? For 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 ...Web
