Web100 000 Pa). So if a leak between two cavities is 200 sccm at 1 bar (100,000 Pa), if we take a linear approximation, the same leak under 7 Pa (worse case scenario) will flow 200*7/100000=0.014 sccm. So the pressure drop does not really impact the measurement of the leaks (0.9 sccm), 1.55% of the leak only. WHAT IS A PASCAL? WebFor example if the pass/fail threshold of an NBC mask is 0.5 sccm, the vacuum channel must be checked for a pass/fail leakage threshold of 0.05 sccm by what is called a vacuum channel leak test. If the JCAST determines that the leak rate of the vacuum channel is in excess of 0.05 sccm, the JCAST will not proceed with the leak test.
Webleakage. When leaks occurred, they generally increased rapidly from 0.1 through the limit of the flow meter (10 SCCM). The graphs show this rapid rise from 0 to 1 0 SCCM leakage in a very short time and temperature span. Testing showed E60C leaked at -31 °C , B70 leaked at-33°C, and GLT leaked at -44°C.

WebMar 27, 2009 · Today, the leak rate limit for a fuel rail is less than 0.5 sccm at a test pressure of 100 psi. “It’s possible to meet that specification with a pressure decay leak test instrument, but if the part is a little warm or if there are changes in the ambient conditions, testing will be difficult,” says Carl Hardt, applications engineer with ATEQ Corp. (Canton, MI).
