​Reliability Data

 


Actuators (pneumatic cylinders) are not taken into consideration in the calculation of performance levels (PL).
Since actuators are not an integral part of the control systems, they do not fall under EN ISO 13849-1 requirements. Manufacturers are, however, required to integrate the risks related to a failure of the actuator into their risk evaluation (EN ISO 14121 and EN ISO 12100).
