4.4 Reliability
The demonstrated Mean Time Between Failures (MTBF) is done through 24/7 testing. Full Intel®
NUC systems in chassis with memory, SSD or HDD, and a fan are ran at 100% on time for 90 days
continuously while running system wide stress inducing software in a 40 °C ambient air
temperature chamber. The demonstrated MTBF for Intel NUC Board NUC13AN is >50,000 hours.
4.5 Environmental
Table 19 lists the environmental specifications for the board.
CAUTION
If the external ambient temperature exceeds 40
o
C, further thermal testing is required to ensure
components do not exceed their maximum operating temperature.
