The appropriate variation between the steam gauge reading and the popping point of a safety valve should not exceed 5 lbs PSI. This standard is set to ensure safe operation within the boiler system.

A properly calibrated safety valve is critical for preventing overpressure conditions. If the difference between the gauge reading and the popping point is too large, it could indicate a malfunction or improper calibration of the boiler's safety mechanisms, potentially leading to hazardous situations.

Maintaining a maximum allowable difference of 5 lbs PSI ensures that the safety valve will operate effectively, providing reliable protection against excessive pressure. This level of tolerance strikes a suitable balance between operational efficiency and safety requirements established by industry standards.
