How to Establish an Acceptable Leak Rate - Cincinnati Test

• 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.

to close and send an alarm. If the expanding air can leak out of a vent hole, the resulting pressure will be reduced. However, if the air expands at a rate faster than the vent hole can compensate for, the contacts will close and an alarm will be sent. Combination heat detectors can combine the two operating principles of

Leak Detection Methods - Thomasnet

The acceptable leak rate, depending on refrigerant type and application, usually spans from 15 g/y (0.5 oz) of refrigerant for large air conditioning systems and/or automotive applications to 0.5 g/y (0.01 oz) for domestic refrigerators. This acceptance level is the main parameter to consider when selecting the ...
