RAM Reliability Centered Maintenance (RCM) 2

Question 1

Which of the following best describes a 'scheduled restoration task' in RCM?

Accepted Answer

Restoring an asset to its original condition at fixed intervals regardless of condition

Answer

A scheduled restoration task involves restoring an asset or component to its original condition at fixed time intervals, regardless of current condition.

Question 2

What criterion must be met for a condition-based maintenance (on-condition) task to be applicable in RCM?

Accepted Answer

There must be a clearly identifiable potential failure condition detectable before functional failure

Answer

An on-condition task is applicable when there is an identifiable potential failure condition (P-F interval) that allows intervention before the functional failure occurs.

Question 3

In RCM, what is the 'default action' when no proactive maintenance task is applicable or cost-effective?

Accepted Answer

Run-to-failure (no scheduled maintenance)

Answer

When no applicable and effective proactive task exists, the RCM default action is run-to-failure (redesign or operate to failure), accepting the consequences.

Question 4

What is the P-F interval in RCM terminology?

Accepted Answer

The time between a potential failure becoming detectable and functional failure occurring

Answer

The P-F interval is the time between when a potential failure becomes detectable (P) and when the functional failure (F) occurs, determining the window for condition monitoring.

Question 5

Which RCM task type is appropriate for addressing hidden failures, particularly in protective devices?

Accepted Answer

Failure-finding task

Answer

Failure-finding tasks (also called functional checks) are specifically designed to detect hidden failures in protective devices by periodically testing their functionality.
