CMRP - Certified Maintenance and Reliability Professional Reliability-Centered Maintenance Analysis Questions and Answers

Question 1

What is the fundamental objective of a Reliability-Centered Maintenance (RCM) analysis?

Accepted Answer

To preserve the intended function of a system or asset within its operating context.

Answer

To eliminate all equipment failures regardless of cost.

Answer

To select the most advanced predictive maintenance technology for every asset.

Answer

To extend the useful life of all equipment components beyond their design specification.

Question 2

An RCM team is analyzing a critical cooling pump. They have defined its functions and identified a functional failure: 'Fails to provide a minimum of 500 GPM.' They have also listed a failure mode: 'Impeller worn beyond tolerance.' According to the structured RCM process (SAE JA1011), what is the immediate next question the team must answer?

Accepted Answer

What happens when this failure occurs (the failure effects)?

Answer

What proactive task can prevent this failure?

Answer

How often is this failure mode expected to occur?

Answer

What is the cost to replace the impeller?

Question 3

During an RCM analysis of a backup generator's auto-start system, the team identifies a failure mode where a control relay fails open. This failure is not apparent during normal operations and only becomes an issue during a power outage. How should the consequences of this failure mode be categorized?

Accepted Answer

Hidden, with potential Safety or Environmental Consequences

Answer

Evident, Operational Consequence

Answer

Evident, Safety Consequence

Answer

Non-operational Consequence

Question 4

Which of the following is NOT one of the seven basic questions that a Reliability-Centered Maintenance (RCM) process must answer, as defined by the SAE JA1011 standard?

Accepted Answer

What is the Mean Time Between Failure (MTBF) for each component?

Answer

In what ways can it fail to fulfill its functions?

Answer

What happens when each failure occurs?

Answer

What should be done if a suitable proactive task cannot be found?

Question 5

An RCM analysis identifies a potential failure mode that has direct and significant safety consequences. Which of the following represents the MOST appropriate hierarchy for selecting a proactive maintenance task?

Accepted Answer

Condition-directed (on-condition) task, followed by a time-directed (scheduled) restoration or replacement.

Answer

Time-directed (scheduled) task, followed by a failure-finding task.

Answer

Redesign the equipment, followed by a run-to-failure strategy.

Answer

Failure-finding task, followed by a condition-directed task.

Question 6

An RCM analysis team evaluates a failure mode on a non-critical conveyor system. The failure effect is minor operational disruption, and there are no safety concerns. The team determines that no applicable or effective proactive maintenance task is cost-justified. What is the most appropriate default action?

Accepted Answer

Implement a No Scheduled Maintenance (run-to-failure) strategy.

Answer

Initiate a complete redesign of the conveyor system.

Answer

Schedule a monthly failure-finding inspection.

Answer

Increase the frequency of operator rounds to check the conveyor.
