A let by test is to make sure that the PCB shuts off. If the PCB does not shut off it will invalidate your tightness test completely! And we prove this in the video with a 60 second let by test. There is actually a gas leak on this installation which been masked by the let by and we set this up to show our gas trainees how important let by

The first part of the test is checking whether or not the emergency control valve is working correctly. To do this, slowly open the valve and keep your eyes on the test gauge you are looking for a reading between 7 - 10 Millibar. Let this sit for 1-minute to ensure you gain a correct reading. Step Four: Now it is time for the Tightness Test itself.

Gas tightness is accepted for a leakage rate of smaller or equal to 10-7 [mbar . L/s]. This means: With a test volume of 1 mL and a test pressure of 103 mbar = 1 bar gauge pressure, which is equal to an absolute test pressure of approx. 2 bar abs. = 2. 103 mbar abs by adding the atmospheric pressure of about 1 bar abs, a pressure decrease is
