What does Condition Based Maintenance (CBM) rely on for decision-making?

Calendar schedules
Noninvasive measurements and tests
Written maintenance logs
Team consensus

The correct answer is: Noninvasive measurements and tests

Condition Based Maintenance (CBM) relies on noninvasive measurements and tests for decision-making, making observables about the condition of equipment the foundation for maintenance actions. This approach emphasizes monitoring the actual condition of equipment through various diagnostic tools, sensors, and analysis methods. By obtaining real-time data, CBM allows maintenance practitioners to determine when maintenance should be performed based on the equipment's health and performance rather than relying on predetermined schedules. This method aims to optimize maintenance activities, reducing downtime and avoiding unnecessary maintenance tasks. It relies on data gathered from the equipment that can indicate wear and tear, potential failures, and operational inefficiencies, allowing maintenance decisions to be proactive rather than reactive. Utilizing noninvasive measurements ensures that the equipment's integrity is maintained while still gathering the necessary information to inform maintenance decisions accurately. In contrast, calendar schedules, written maintenance logs, and team consensus do not provide the same data-driven approach and may lead to either unnecessary maintenance activities or missed opportunities for timely interventions based on actual equipment conditions.
