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 13849-1 is the Safety Related Parts of Control System (SRP/CS), defined by the norm as: Part of a control system that responds to safety-related input signals and generates safety-related

Vi kan ge stöd både för Performance Level enligt EN13849 samt SIL enligt Riskbedömningar/Processäkerhetsanalyser för att avgöra vilka funktioner som kan 

Risk assessment for determining the required SIL level is based on severity of injury (Se), frequency and duration of exposure (Fr), probability of occurrence of a hazardous event (Pr), and probability of avoiding or limiting harm (Av) EN/ISO 13849-1 SS-EN ISO 13849-1:2008 och har utgivits i engelsk språkversion. Detta dokument återger EN ISO 13849-1:2008 i svensk språkversion. De båda språkversionerna gäller parallellt. Denna standarden ersätter SS-EN ISO 13849-1:2006, utgåva 1. The European Standard EN ISO 13849-1:2008 has the status of a Swedish Standard. The standard was RISK ASSESSMENT AND RISK REDUCTION FOR MACHINERY RISK ASSESSMENT AND RISK REDUCTION FOR MACHINERY Introduction Scope Machine risk assessment consists of a series of steps used to examine the hazards associated with machines and it consists of two stages, namely risk analysis and risk evaluation, as laid out in ISO 12100:2012.

The ISO 13849-1 methodology uses the category of circuit structure/architecture, mean time to dangerous failure (MTTFd), number of cycles with which 10 percent of components have a failure to danger (B10d), diagnostic coverage (DC) and common cause failure (CCF) to determine the PL of a control system. The next part of the report describes shortly how to perform a risk assessment and define an appropriate PLr(Performance Level required) for each identified safety function. A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions. 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). The required PL is determined and assigned as part of the risk assessment in accordance EN ISO 13849-1.

Step 1 – Risk assessment A risk assessment begins with determining the scope of the machine. This includes the space that the machine and its In the risk assessment method described in EN 13849 (see figure below) we follow the tree and realize that we end up with S=1 (you cannot severe your hand but it can hurt), F=2 (you are working close to the function) and P=2 (it is unlikely that you will be able to react quickly enough if something goes awry). requirements for the risk assessment of a machine.

ISO 13849-1.

Even when the Markov method is used, however, machines exist which execute numerous hazardous movements in a confined space, which leads to the permissible PFH being exceeded. In the risk analysis, safety functions for risk reduction have been defined and a PLr assigned to them.
