Directive and the harmonised stan-dards is illustrated by the diagram below. According to EN ISO 13849-1 the risk is estimated using three factors: injury

Standardization of a reliability data exchange format (VDMA) 6. David Collier of the Machinery Safety Alliance has written an article that dispels the myth that machine risk assessments are covered by the risk graph in EN ISO 13849-1 (or EN 954-1 as was). The new article article introduces EN ISO 12100:2010 , which is the current standard used for risk assessment and risk reduction on machines. ISO 13849-1, Pl. a IEC 61508, sil 1. IEC 62061, sil 1. IEC 60730-1, Class B. Note that ISO 13849-1 risk graph is very binary with little granularity. This tends The output of the risk graph indicates a required performance level of a – e, clearly the greater the risk of exposure to a hazard, the higher the performance of the safety related control needs to be.

This information then can be used in a risk assessment (e.g. ISO 12100, ANSI B11.0, etc.) to evaluate and ensure the appropriate risk reduction has been achieved

Background: EN ISO 13849-1 The normative requirements governing safety-related machine controls are set out in close detail in the applicable safety standard, EN ISO 13849 (formerly EN 954). After ten years' successful application, Part 1, "Safety of machinery – Safety-related parts of control systems: General principles for design", was subjected to a thorough revision and republished in 2006.

ISO 13849 – 1:2015 provides a graphical means for selecting the minimum Performance Level (PL) required for the safety function based on the risk assessment.

9. This information then can be used in a risk assessment (e.g. ISO 12100, ANSI B11.0, etc.) to evaluate and ensure the appropriate risk reduction has been achieved When using EN ISO 13849-1 the required performance level (PLr ) has to be defined by using the risk graph. Attention!
