Questions regarding the hydrostatic test values.
Thread Content
How many decimal places should be retained for the hydrostatic test values? Round it off? Is it related to the accuracy of the pressure gauge? :Q
At most two digits; pressure gauges do not have such high precision.
The accuracy class of the pressure gauge is 1.6. The method for calculating the allowable error is: A=±(measurement range of the gauge)×1.6%. For example, if the measurement range of the gauge is 0~10 MPa, the allowable error is ±0.16 MPa. If the measurement range is -0.1~1.5 MPa, the allowable error is ±0.0256 MPa
2 digits after the decimal point are sufficient.
:victory: Thank you
Retain at most two decimal places
The third floor explained it in great detail; we usually only take the last two digits
