How to testing of Pressure relief valve as per API 6D ?

#1
I have a valve which has pressure relief valve placed on the valve. How to test working of the pressure relief valve for the validation of the valve.

Please provide any idea or sketch or video for the same.

Pressure-relief valve opened by the static pressure upstream of the valve and is characterized by a rapid opening or pop action. When the static inlet pressure reaches the set pressure, it will increase the pressure upstream of the disk and overcome the spring force on the disk. The fluid will then enter the huddling chamber, providing additional opening force. This will cause the disk to lift and provide a full opening at minimal over-pressure. The closing pressure will be less than the set pressure and will be reached after the blow-down phase is completed.

You have to do shell test, seat test CDTP test and ensure that no leakage is allowed.

For more understanding, can you share the drawing for the same?
