[MW:33345] HydroTest Pressure recorder and chart- Range selection

Dear Sirs,

In case of Hydrotest, as per ASME Sec VIII Div-1, UG-102 (b), 

only for the dial indicating gauges,

the range has been given such as 1.5 to 4 times of the test pressure, when selecting the pressure GAGEs.

But, for Pressure Test Recorder with the chart, is there any requirement in either ASME CODE Or any other project spec, given the range of selection of Pressure recorder like the dial indicating gages for the test pressure.

Please share your views.

Regards,

Saravanan Sornam,

Korea.
