This document was prepared to help explain Figure 1 The safety function workflow from ISO 13849-1 Figure 3 in the standard (see Figure 1 above) describes the work flow from identifying that a safety function shall be performed by SRP/CS until the safety function has been validated. Maskinsäkerhet - Säkerhetsrelaterade delar av styrsystem - Del 1: Allmänna konstruktionsprinciper (ISO 13849-1:2015) - SS-EN ISO 13849-1:2016Det här innebär standarden Den här delen av standard SS-EN ISO 13849 fastställer säkerhetskrav för samt vägledning kring konstruktion och integrering av The EN/ISO 13849-1 machine safety standard uses a qualitative risk graph, or flow chart, to assign a performance level (PL), based on three criteria: severity of injury; frequency and/or exposure time to the hazard; possibility of avoiding the hazard or limiting the harm ISO/TR 23849, Guidance on the application of ISO 13849-1 and IEC 62061 in the design of safety-related control systems for machinery 3 Terms, definitions, symbols and abbreviated terms 3.1 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 12100 and IEC 60050-191 and the following apply.


Iso 13849-1 category 3

A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions. Categories were used also in the earlier machinery safety • Safety Standards ISO13849-1 for Category 3 and 4 This product is designed to be used as a component in a Category 3,4 safety system. The required PL is determined and assigned as part of the risk assessment in accordance EN ISO 13849-1. EN ISO 13849-1/-2: Safety of machinery – Safety-related parts of control systems As the successor to EN 954-1, EN ISO 13849-1 is the main safety standard for the design of safety-related control systems for machinery. Safety Category 3 / PL (d) Performance Definition To achieve Safety Category 3 / PL (d) according to EN ISO 13849-1, the safety-related parts have to be designed such that: • The safety-related parts of machine control systems and/or their protective equipment, as well as their components, shall be designed, constructed, selected, 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. ISO 13849-1 provides a scoring process and quantification of measures against CCF. The total score must be 65 or better.

The EU Machinery Directive stipulates that machinery should not present a EN ISO 13849-1 describes four levels how the safety system is tested . Certified safety electronics, certified in accordance with DIN EN ISO 13849-1, PLe; Certified is certified in accordance with DIN EN 13849-1 Category 4 PLe through DGUV. Based on Table 3 of DIN EN 13849-1, this corresponds to SIL 3.
