EN 13849-1 was put into place in 2006 in order to replace EN 954-1. The main reason for that was to also consider the importance of failures-in-time of the design and its components, not only its architecture as for 954-1. However, the machine norms, e.g. EN 15011 for bridge and portal cranes still kept EN 954-1 as the relevant norm for the safety of the electrical equipment of the crane.
The SS-EN ISO 13849-1:2016 Maskinsäkerhet – Säkerhetsrelaterade delar av styrsystem – Del 1: Allmänna konstruktionsprinciper (ISO 13849-1:2015) Safety of machinery – Safety-related parts of control systems – Part 1 4.5.1 Performance level PL that EN 954-1 is above criticism. Rather, it is much more concerned with asking whether a complete replacement which is not automati-cally downward compatible is necessary. EN 954-1:1996 IEC 61508:1998–2000 EN ISO 13849-1 It examines complete safety functions, including all the components invol- ved in their design. EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions. A performance level (PL) is used for this, building upon the categories. BS EN ISO 13849-1 has just been published and provides guidance on the principles for the design and integration of safety-related parts of control systems, including the design of software. BS EN ISO 13849-1:2015 Safety of machinery.
Performance levels (PL) are defined in EN ISO 13849-1 to classify different safety-related capacities into their respective categories. IEC/EN 62061, PL and (EN) ISO 13849-1:2008, Comparison of PL and SIL Chapter 7 System Design According to (EN) ISO 13849 66 SISTEMA, Safety System Architectures (Structures), Mission Time, Mean Time to Dangerous Failure (MTTF D), Diagnostic Coverage (DC), Common Cause Failure (CCF), Systematic Failure, Performance Level (PL), Subsystem Design ”Performance level d”? A Performance Level (PL) is a discrete level used to specify the ability of safety-related parts of control systems to perform a safety functions under foreseeable conditions. PL=d is the second highest reliability classification, meaning that the safety function is extremely reliable.
• The safety function requirements are derived from the necessary risk reduction. Why Category 2 is unsuitable for Performance Level d safety Under EN 954-1 (still scheduled for withdrawal at end 2011) the 'Category' of the control system has been used as the basis for constructing the safety-related control functions.
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
