Burn-in testing involves operating equipment or systems for a defined period to identify early failures, instability, or configuration problems before formal acceptance.

Depending on the product and project, this may involve continuous operation, repeated functional cycles, or monitoring system behavior over time.

Burn-in procedures are not necessary or appropriate for every equipment category and should follow relevant manufacturer guidance. For systems where early instability could affect many guestrooms, an agreed observation period may provide additional confidence before the project is fully handed over.
