What condition would trigger thermographic survey instead of the calendar?

Connection temperature above ambient by 10 C (investigate) or 35 C (act), or above the adjacent phase by 10 C; continuous temperature sensing on busbars and terminations replaces the periodic scan on critical boards

What reading proves thermographic survey was done?

Temperature rise over ambient and over the adjacent phase at each connection, under recorded load. Observed by: Thermal imaging camera under load; wireless temperature sensors on critical terminations.

What evidence does thermographic survey produce for an ISO 55001 or ISO 45001 audit?

Survey report per board with images, load at the time and the temperature rise per finding, and the repair record

Thermographic survey

Q: Can thermographic survey move from a fixed interval to a condition-based check?

Convertible: a monitored condition can replace the fixed interval. A loose connection heats up long before it fails, and an annual scan has a one in twelve chance of being in the right month. Sensors on the boards that matter watch every day.

Condition that replaces the interval: Connection temperature above ambient by 10 C (investigate) or 35 C (act), or above the adjacent phase by 10 C; continuous temperature sensing on busbars and terminations replaces the periodic scan on critical boards
Reading that proves it: Temperature rise over ambient and over the adjacent phase at each connection, under recorded load
Evidence an auditor accepts: Survey report per board with images, load at the time and the temperature rise per finding, and the repair record
First move: Scan under at least 40% load and record the load; a scan on a lightly loaded board proves nothing.
