5.4.1.6.3.1 Characteristic values
The following matrix shows the relationship between potential failures and the suitability of the characteristic values
provided in the module for error analysis. The potential failures refer to the individual application possibilities.
This assessment is based on an estimation of typical applications.
Application possibilities
