What condition would trigger refrigerant leak check instead of the calendar?

Partly. Fixed leak detection in the plant room and an automatic charge monitor on the system detect a leak continuously; the periodic leak check is set by F-gas or refrigerant law by charge size and cannot be dropped, though fixed detection doubles the permitted interval.

What evidence does refrigerant leak check produce for an ISO 55001 or ISO 45001 audit?

Refrigerant leak check

Q: Can refrigerant leak check move from a fixed interval to a condition-based check?

Statutory: the interval is set by law or a statutory code and stays on the calendar. Leak check intervals are set by the EU F-gas Regulation and UK equivalent by charge in CO2 equivalent (every 12, 6 or 3 months, halved again without fixed detection), and by EPA Section 608 in the US.

The law sets the interval by charge size and gives you a longer one for fitting detection. That is the conversion on offer: fit the detector, halve the visits, keep the log.

What does a refrigerant leak check involve?

Refrigerant leak check checks: refrigerant charge (kg) against nameplate, fixed detector reading (ppm), superheat and subcooling. Observed by fixed leak detector; automatic leak detection system on the circuit; handheld detector at the check. Leak check intervals are set by the EU F-gas Regulation and UK equivalent by charge in CO2 equivalent (every 12, 6 or 3 months, halved again without fixed detection), and by EPA Section 608 in the US.

Condition that replaces the interval: Partly. Fixed leak detection in the plant room and an automatic charge monitor on the system detect a leak continuously; the periodic leak check is set by F-gas or refrigerant law by charge size and cannot be dropped, though fixed detection doubles the permitted interval.
Reading that proves it: Refrigerant charge (kg) against nameplate, fixed detector reading (ppm), superheat and subcooling
Why the interval stays: Leak check intervals are set by the EU F-gas Regulation and UK equivalent by charge in CO2 equivalent (every 12, 6 or 3 months, halved again without fixed detection), and by EPA Section 608 in the US.
Evidence an auditor accepts: Leak check record per system in the F-gas log with the charge, method, result and the technician's certification
First move: Record the charge in CO2 equivalent on every system so the correct statutory interval is visible on the register.
