General Reliability Technician Practice Questions (1-50)
1. What does PMP measure in a maintenance context?
a) Labor hours per month
b) The ratio of planned maintenance to total maintenance
c) Production volume per shift
d) Inventory turnover rate
Answer: b) Planned Maintenance Percentage (PMP) is a key
metric that indicates the effectiveness of a proactive maintenance
strategy by measuring how much maintenance work is planned
versus unplanned .
2. What is a primary benefit of predictive maintenance?
, a) Reduces production speed
b) Extends equipment life and reduces unplanned downtime
c) Increases inventory requirements
d) Eliminates the need for maintenance personnel
Answer: b) By targeting potential failures, predictive maintenance
helps avoid unexpected breakdowns and prolongs the life of
equipment .
3. Which analysis method ranks failure causes from most to
least frequent?
a) Root cause analysis
b) Pareto analysis
c) FMEA
d) Trend analysis
Answer: b) A Pareto analysis is used to prioritize corrective
actions by identifying the most common and impactful causes of
failure .
4. Which lubrication practice is critical for preventing bearing
failure?
a) Over-lubrication
b) Clean handling and sealing of lubricants
c) Using minimal oil
, d) Switching lubricant types frequently
Answer: b) Keeping lubricants free of contaminants is essential
for bearing longevity and reliability .
5. Which maintenance strategy is least effective for non-
critical equipment?
a) Run-to-failure
b) Preventive maintenance
c) Predictive maintenance
d) Reliability-centered maintenance
Answer: c) The cost of predictive monitoring is often not justified
for non-critical equipment, where a simpler "run-to-failure" or
preventive approach is sufficient .
6. The "bathtub curve" illustrates what?
a) Equipment performance over temperature
b) Failure rate over equipment lifecycle
c) Maintenance cost over time
d) Labor efficiency over shifts
Answer: b) The bathtub curve maps the typical failure rate of
equipment over its life, showing high "infant mortality" failures, a
period of constant failures, and finally a "wear-out" phase .
, 7. What best describes an effective reliability program metric?
a) Employee satisfaction
b) Ratio of planned vs. unplanned maintenance
c) Production volume
d) Inventory levels
Answer: b) A high ratio of planned to unplanned maintenance is
a strong indicator that a reliability program is effectively
preventing failures.
8. What is the primary objective of a lubrication program?
a) Reduce energy consumption
b) Ensure equipment operates reliably and reduces wear
c) Eliminate maintenance personnel
d) Increase production speed
Answer: b) Proper lubrication is fundamental to minimizing
friction and wear, which is key to extending equipment life and
ensuring reliable operation .
9. Which metric indicates the average cost of maintaining a
system per unit of production?
