A gas leak tester is only as good as the parameters you run it with. Set the pressure too low and you miss small leaks; set the hold time too short and the test passes stoves that fail in the field. Getting these parameters right is the foundation of a safe assembly operation. Here is what to know.
The gas system should be tested at a pressure above its normal operating pressure, so any weak joint is exposed. The exact figure depends on the gas type and the appliance standard you follow, but the principle is universal: test higher than you run, so the margin of safety is real.
After pressurizing, the system holds for a set time while the tester watches for pressure drop. A short hold catches gross leaks; a longer hold catches slow, weeping leaks. Balance the two against your line speed — a proper test should be long enough to be meaningful without becoming a bottleneck.
Define a clear pass/fail threshold for pressure drop, and make sure the tester is calibrated so the result is repeatable. The same stove tested twice should give the same answer. Document the parameters so every operator runs the identical test.
Leak testing should cover the entire gas system, not just one burner. Verify each burner's connection and the main manifold. THREEMI advises CKD partners on leak test equipment selection and parameter setting, so your line meets safety standards consistently from the first stove to the ten-thousandth.
