5 Check the condition of the tested parts.
Probable Cause Treatment
Part temperature is higher or lower
than the ambient temperature.
Let the part temperature be ambient by adding a cooling/warming buffer in
the production line.
The tested parts are wet. Improve the drying process or add one if there isn't any.
The tested parts get deformed by
pressurization.
Add a stopper to prevent the deformation.
Leak due to the gas porosity or
internal leak
Look for leaks in the fittings by performing a bubble test applying soap
solution.
Redo the tubing if needed.
If no leak is confirmed, there may be internal leaks.
If there is a leak, re-evaluate the production process.
