Leak testing windshield reservoirs is challenged by the large volume of each part. Unlike parts with small volumes, the time required to stabilize test conditions is always longer when such large volumes are involved.
Even the best pressure decay leak test systems prove slow—and typically are far too inaccurate—because of this requirement for time to stabilize test conditions in large volume parts.
Mass flow test systems are inherently superior because they are less affected by temperature and pressure variations. However, not all mass flow leak test sensors are alike.
Further, the ever-present drive to eliminate fat wherever possible in leak test methods are such that InterTech’s world-renowned test engineering specialists asked…contact IDC for more info….
