Andy MTBF is obtained by testing a number of units over a period of time at accelerated environmental conditions. First the infant mortality of a product is determined and then the MTBF is deduced. Some suppliers have an MTBF based on the number of products produced compared to the number of returned or reported failures. Not always very scientific or even accurate. So 1700 hours could be correct for products that are subjected to sales over faults reports.
Doing MTBF and infant mortality tests are usually reserved for military or mission critical equipment and is very expensive to conduct as all the samples are usually tested to destruction in order to determine useful life expectancy.
