7.1 Liability
exida prepares reports based on methods advocated in International standards. Failure rates
are obtained from a collection of industrial databases. exida accepts no liability whatsoever for
the use of these numbers or for the correctness of the standards on which the general
calculation methods are based.
Due to future potential changes in the standards, best available information and best practices,
the current FMEDA results presented in this report may not be fully consistent with results that
would be presented for the identical product at some future time. As a leader in the functional
safety market place, exida is actively involved in evolving best practices prior to official release
of updated standards so that our reports effectively anticipate any known changes. In addition,
most changes are anticipated to be incremental in nature and results reported within the
previous three year period should be sufficient for current usage without significant question.
Most products also tend to undergo incremental changes over time. If an exida FMEDA has not
been updated within the last three years and the exact results are critical to the SIL verification
you may wish to contact the product vendor to verify the current validity of the results.
