This standard was greatly revised in November 2006. This revision has caused major changes in the fundamentals of safety system design. This document was prepared to help explain 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).
While there are two different standards, the scope of each standard is very similar. Note that either a SIL or Performance Level would be used, but not both. The figure below shows an overview of the risk assessment process: and performance levels (PL) are comparable (see Table 7). This document includes safety performance/ integrity examples for both standards. ISO 13849-1 – for making machines safe ISO 13849-1 provides instructions to designers to make machines safe. These instructions include recommendations for system design, integration and validation.

EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions.

EN ISO 13849-1 is the most important standard for regulating the basic principles and performance required of a safety control system for machines and devices. This standard was greatly revised in November 2006. This revision has caused major changes in the fundamentals of safety system design.

In other cases (mainly sensors) there are values given in the documentation that allow building a category 3 application by using the devices in redundancy. This part of ISO 13849 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. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. 2012-01-06 BS EN ISO 13849-1:2006 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. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. For the design of such products, it is important to refer to the specifically applicable International Standards, e.g.

La situazione pericolosa viene suddivisa in cinque livelli, i cosiddetti Performance Level (PL), da PL "a" (basso) a PL "e" (alto). Poziom Performance Level jest pasmem prawdopodobieństw uszkodzeń niebezpiecznych, zdefiniowanym w tablicy 2 normy PN-EN ISO 13849-1 Zakresy pokazane w tablicy 2 są przybliżone. Jeśli chcesz konkretne sprawdzić granice tych pasm, spójrz do załącznika K nomy PN-EN ISO 13849-1, który opisuje pełną rozpiętość PFH D w formie tabeli. 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. Performance level (PL) was introduced in ISO 13849-1: 2006, which is quantitatively expressed as the reliability of safety-related parts of a control system, including diagnostic coverage or failure rate.

EN ISO 13849-1, including its Amendment 1, formulates requirements with the aid of which safety-related controls of machinery can easily be developed, validated and certified. The standard com- IEC 62061 addresses SIL levels and ISO 13849-1 addresses Performance Levels. While there are two different standards, the scope of each standard is very similar.
