- After performing the set up above, ensure that there is no leak.
- Increase the pressure until a sudden release or pop action is observed.
- Check the displayed pressure reading in the standard and record in your Measurement Data Sheet (MDS).
What is pop test for safety valve?
“Pop Test” is a set pressure test of Pressure Relief Valve (PRV) by compressing the pressure into the inlet of PRV until Valve opens. The pressure that causes Valve to open (Pressure) will be compared with the Set pressure of the PRV to see how Valve open pressure on the set or not.

What is the function of a pressure relief valve?
Relief Valves are designed to control pressure in a system, most often in fluid or compressed air systems. These valves open in proportion to the increase in system pressure. This means they don’t fly all the way open when the system is slightly overpressure.
