Does anyone know any test (pneumatic or electric) that avoid destroying parts to verify leakage in closures? Someone told our production supervisor that there is a "voltaic arc" that is a non destrutive test.

I am looking for devices in Brazil also, if anyone knows.

Kindly regards,

Alekra

Are you referring to the 'Holiday test' (http://www.buckleys.co.uk/holidayguide.htm) used to detect pinholes, etc. for pipe insulations?

Hello alekra,

Would this be of help? http://www.nema.org/stds/results.cfm?srchString=enclosures&UserSelectedSubSites=12

I was in plastic closures field in my past life. I am not personally aware of any testing that would consider non-destructive to verify leakage. Generally, you would want to apply pressure to check for leakage on a closure. Once you apply the pressure, it changed the character of the closure. The changes in the closure may not be "visible", however, once you apply the pressure, it will certainly change the character of the closure. We called the test SST (Secure Seal Test). I can't remember the manufacturer's name, but I'm sure you can find equivalent equipment in Brazil. It's just a basic tank with water. You will however need the air line for pressure and/or nitrogen tank (depending on the intended use of the closure).

Thanks for all the answers! I could learn from all of them!

I got a nice equipment from Google, starting from the name that Qualitychic has suggested. It is not electrical, but is for leakage. I will show them to my colleagues to decide which will be better.

The idea is not to loose so many parts with destructive tests. Nowadays we have a device were the closure is assembled under the water and air is injected. If bubbles appears through the closure, there is leakage - FAIL. But we have a lot of "scrap" due to that (we recicle the parts, but we´d rather not to generate scrap).

Regards and thank you!
