→13.3.1 Measuring of Contact Resistance
By adding an upper threshold value (for ex. the 90% contact resistance value of the statistical cumulative frequency) it can be assured that that contacts are fulfilling the requirement from their new state for the respective application. The current carrying in normally dynamically operating devices is also assured by this measurement procedure. It is however not a valid indicator for the further behavior in a given application. To determine this, electrical life tests have to be performed under real electrical loads.
