Rodney
Leak Test

Hello!! My name is Rodney and I work for a railcar repair facility in the US. Just recently we were told that we would have to develop a sensitivity and reliability for our Leak Test Procedure. We have done countless hours of research to see what exactly we have to do to fulfill this requirement, and so have been unsuccessful. Can anyone help or point me in the right direction?

Re: Leak Test Rodney

I'm sure some of us can help, but leak testing is a varied field.

can you advise:

What are you testing for leaks -e.g. Bodies, Doors/windows, pneumatic systems etc?

What method(s) are you using? e.g. Ultrasonic, Gas detection, pressure drop, bubbles, smoke?

Where has the requirement com from - is it a specific requirement, or simply "how can you show that you are doing what you say you are?"

All the best
Joe

Re: Leak Test We are testing tank cars using the bubble leak method. From my understanding, the only requirement is to simply show that we are doing what we say we are, but I am unsure what sensitivity and reliability actually are. I really appreciate any help that you can provide. Thanks!!!!!!!

You can do the test with Ultrasonic (Airborne) Leak Tester - which is available in the market. 1x10-6 std cc per second can be detected using the above.

You can contact UE Systems - they have different models and also SDT System. Sonatest too had a small one.
