Hi,

Long story short, if I want to check if my check ring is leaking (or barrel is the cause but that's not the point) I turn off HR (for example) and then at different screw positions I increase the holding pressure incrementally. At some point the screw starts moving forward but slowly. My question is how much leaking is acceptable. I think the borderline is blurry and it is process dependent. I would like to make a standard in my company so that no matter who does this test everybody should have the same judgement regarding this test.

What are your experiences?

Thanks,
Robert
