Can pressure test (hydrostatic or pneumatic) move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. A periodic proof test may be required by the written scheme or code, but a routine pressure test on a system that is monitored continuously duplicates what the transmitter already shows.

What condition would trigger pressure test (hydrostatic or pneumatic) instead of the calendar?

Partly. Continuous pressure monitoring on a system held at pressure detects a leak between tests; a test after modification or as part of a statutory examination stays.

What reading proves pressure test (hydrostatic or pneumatic) was done?

Pressure held over the test duration with the allowable drop, test pressure against design. Observed by: Calibrated gauge or transmitter with a logged hold period.

What evidence does pressure test (hydrostatic or pneumatic) produce for an ISO 55001 or ISO 45001 audit?

Pressure test record with test pressure, duration, drop and the gauge calibration reference

Pressure test (hydrostatic or pneumatic)

A system at working pressure with a transmitter on it is being pressure tested all day. Keep the proof test where a code requires it; drop the routine one.

Condition that replaces the interval: Partly. Continuous pressure monitoring on a system held at pressure detects a leak between tests; a test after modification or as part of a statutory examination stays.
Reading that proves it: Pressure held over the test duration with the allowable drop, test pressure against design
Why the interval stays: A periodic proof test may be required by the written scheme or code, but a routine pressure test on a system that is monitored continuously duplicates what the transmitter already shows.
Evidence an auditor accepts: Pressure test record with test pressure, duration, drop and the gauge calibration reference
First move: Check whether each pressure test on the list is required by a written scheme; if not, the transmitter log replaces it.
