How to Establish an Acceptable Leak Rate - Cincinnati Test
www.cincinnati-test.com• The characteristics of the hole (or leak) that determine whether it will leak are the smallest diameter in the hole path, the path length of the hole through the part material, surface tension, and the surface finish of hole (leak). Hole Size - The smallest opening in the flow (leak) path controls the rate of flow through the path.
