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

Replacing a component before its failure probability increases significantly

Answer

Monitoring asset condition to schedule restoration at the optimal time

Answer

Restoring an asset only after a functional failure has occurred

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

The failure must be detectable by human senses alone

Answer

The P-F interval must exceed one year

Answer

The asset must have been in service for more than five years

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

Increase inspection frequency

Answer

Replace the asset with a more reliable model

Answer

Implement a manual workaround procedure

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 time between planned maintenance and functional failure

Answer

The interval between preventive maintenance tasks

Answer

The probability-frequency factor used in risk calculation

Question 5

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

Accepted Answer

Failure-finding task

Answer

Scheduled discard task

Answer

Scheduled restoration task

Answer

Condition monitoring task

Question 6

In an RCM analysis, the Failure Mode and Effects Analysis (FMEA) is used to:

Accepted Answer

Identify failure modes and their effects on asset function and operation

Answer

Calculate the financial cost of each failure mode

Answer

Determine the optimal maintenance interval for each task

Answer

Rank failure modes by frequency of occurrence only

Question 7

What is the key difference between RCM and traditional time-based preventive maintenance?

Accepted Answer

RCM selects maintenance tasks based on failure consequences and characteristics, not fixed intervals

Answer

RCM only applies to safety-critical equipment

Answer

RCM eliminates all scheduled maintenance in favor of condition monitoring

Answer

RCM is exclusively used in the aviation industry
