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. e. ≥10 -8 and <10 -7.
Up to performance level PL e according to EN ISO 13849-1; Up to safety integrity level SIL CL 3 according to IEC 62061; Up to 5 enabling-current paths and 2
The requirements for developing systems at different levels can vary greatly in cost. A free EN ISO 13849-1 Performance Level Calculator is available from the IFA (Institut fuer Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung) in Germany. This simple tool, developed in conjunction with the German ZVEI and VDMA organisations, consists of two discs; rotating the bottom disc reveals different values through windows cut in the top disc. EN ISO 13849-1:2006 Performance levels Performance Level (PL) is related to the Probability of Dangerous failure per Hour (PFHD) The standard give a simplified ISO 13849-1:2015 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software.

This revision has caused major changes in the fundamentals of safety system design. EN ISO 13849-1: Performance Level (PL) The greater the risk, the higher the requirements of the control systems.

This standard was greatly revised in November 2006. This revision has caused major changes in the fundamentals of safety system design. EN ISO 13849-1: Performance Level (PL) The greater the risk, the higher the requirements of the control systems. The hazardous situation is classified into five levels, known as Performance Levels (PL), from PL "a" (low) to PL "e" (high).

Performance levels in BS EN ISO 13849-1 are defined in terms of probability of dangerous failures per hour (Table 3, clause 4.2.2) Performance level and SIL There is clearly a correspondence between the SIL required accord-ing to 62061 and the PL required according to 13849.
For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. PL EN ISO 13849-1 Performance level: corresponds to SIL, Levels a-e SIL EN/IEC 62061 Safety integrity level Note: This is an indicative example. Relevant installation, design and safety calculations need to be speficially completed for each system implementation according to machinery safety standards (EN/IEC 62061, EN ISO 13849-1, EN ISO 13850 Within the field of machinery safety, standards relating to the safety related parts of the control system have been a topic of concern for some time.
