PL-c vs. PL-d 2006/42/EC MACHINERY DIRECTIVE EN ISO 13849 Safety of machinery – Safety related parts of control systems – General principles for design » EN ISO 13849 is an international standard common in the EU » Defines required Performance Level (PL) for safety function » Categorizes five Performance Understanding Performance Levels. To understand ISO 13849 – 1, it helps to know a little about where the standard originated. ISO 13849 – 1 is a simplified method for determining the reliability of safety-related controls for machinery.

EN ISO 13849-1: Performance Level (PL) Ju högre risk desto högre är kraven på styrsystemen. Risksituationen bedöms efter en skala med fem steg, så kallade Performance Levels (PL), från PL ”a” (låg) till ”e” (hög).

How is the disc used? To determine the probability of dangerous failure (PFH D) and the associated Performance Level Performance Level i olika nivåer I ISO 13849 -1 finns definierat fem olika Performance levels från Performance Level A till Performance Level E där Performance Level A ger minst riskreduktion och Performance Level E ger mest riskreduktion. Performance Levels are only referenced in one standard, ISO 13849. Safety Integrity Levels are referenced in IEC 61508 and all the other standards derived from it. But ISO 13849 is pivotal because of its role in the new Machinery Directive, so it is quickly making EN 954 obsolete, along with the safety “categories” referenced in EN 954. The latter are being replaced by Performance Levels. Each architecture is associated with a formula to determine the probability of dangerous failure per hour (PFH d) of the subsystem.

Mean Time to Dangerous Failure. In a safety system MTTF D is the portion of failure modes that can lead to failures that may result in hazards to personnel, environment or equipment.. MTTF D is critical to the determination of the performance level of a safety system. ISO 13849 defines three levels of MTTF D:
The topic of EN 13849-1, introduced on October 2006, is the reliability of safety systems, replacing the previous EN 954-1. The field of application of EN 13849
