Durability as per

Performance level 2 = 250 mating cycles in total.

IEC 61 076–4–101

 

First 125 mating cycles, then 4 days gas test using 0.5 ppm SO2 and 0.1 ppm H2S (at 25 + 2 °C and 75 + 3 % humidity). Measurement of contact resistance.

 

 

 

 

 

 

The remaining 125 mating cycles are subject to measurement of contact resistance and visual inspection. No abrasion of the contact finish through to the base material. No functional impairment.
