Ten high-intensity bulbs are tested for 100 hours each. One failed at 40 hours; another failed at 70 hours; all others completed the test. Calculate FR(%), FR(N), and MTBF.
High-Intensity Bulbs
Light bulbs designed to emit a brighter light compared to standard bulbs, often used in areas requiring high levels of visibility.
FR(N)
Refers to the function assessing the rate at which a system or component fails, emphasizing its reliability over time.
- Determine the Failure Rate (FR), Failure Rate Normalized (FR(N)), and Mean Duration Between Failures (MTBF).
