MTBF

13 MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical
device failures, and indicates reliability of a device. It is the statistical representation of the
likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail.
A MTBF figure of e.g. 1 000 000h means that statistically one unit will fail every 100 hours
if 10 000 units are installed in the field. However, it cannot be determined if the failed unit
has been running for 50 000h or only for 100h.
