Meeting Reliability Standards for
Commercial Use
To conclude that a device meets reliability
standards for commercial use, reliability test
engineers have several responsibilities:
■■ Determining if a device will survive
environmental stresses and continue to meet
specifications
■■ Answering customer questions about device
lifetime (MTBF, MTTF)
■■ Providing key insight into device fit for
certain high reliability applications (mil/aero,
automotive, etc.)
Creating statistically relevant results requires
sufficient sample sizes of the test devices. The
nature of stress-measure cycling over many
devices necessitates multi-channel parallel test
with automated data evaluation
