    Volume of Item being Tested by a Vacuum Tank

    CompositePro, [indent]I agree with the big size. I hadn't even brought that into this discussion, but that is the other factor. The square area of the bag surface that pressure is being applied would certainly affect the force that is being exerted overall on the seals. That's a point I made a...

    Volume of Item being Tested by a Vacuum Tank

    "Without a standard volume in the pouch, your "test" is fatally flawed IMHO, as your reading of the reduced pressure is not going to be the same as the differential pressure in the pouch and hence the test is not repeatable." "Exactly. That "industry standard", if it does not address the...

    Volume of Item being Tested by a Vacuum Tank

    BigInch, Thanks for the feedback, unfortunately, this is a test that is accepted and verified by our customers really as an industry standard. We do some pressure testing, but that testing is geared towards the tensile strength of the seal, and its bursting capacity as opposed to its leak...

When you close the lid, it forces the pouch under the water, and then we slowly evacuate the air from the tank...
