    2007/3/20 · You might want to refer to ASME Boiler and Pressure Vessel Section V Article 10 Leak Testing. The helium leak testing sensitivity would be 1 x 10E-06 stc cm3/sec as you have noted. The bubble leak testing method would be much less sensitive at 1 x 10E-02 std cm3/sec. and the hydrotest leak sensitivity would be even less at 1 x 10E-01 std cm3/sec.
