Pneumatic test

[TRO]

hello,

I have a short question about the calculation of the pneumatic test pressure.

When I select the pneumatic test pressure to be equal to 1,1 times the calculated test pressure per UG 100 (b), I expect it to be equal to 1,1 times the MAP (which is 423.91 kPA). But compress gives a value of 418.34 kPa, which is lower.

Can someone explain how this value is calculated?

Be sure to set the test liquid specific gravity to 0 or an appropriate value. See the Set Mode Options dialog, Testing tab; or the Liquid Level, Test liquid input.
