Is there anywhere in the code that specifies the accuracy of the hydrotest gauge? I don't mean the range where the gauge is most accurate but how "sensitive" (+ or - X%) must the gauge be? If you are doing a 350 PSI hydro (random #) must the gauge be accurate to .5 #, 1#, 5#, etc.)? It is understood that a calibrated gauge is used.

test gages UG-102

1.5 no more than 4 times the test pressure... is that what ur wondering.
I think that would cover the sensitivity.

The accurate range to use between 10 - 2 o'clock.
