It is generally accepted that the majority of industry uses ISO 13849-1 (PL) because the machine builders were previously using EN 954-1, which have naturally migrated to ISO 13849-1 (PL). This is reinforced by a survey illustrated below that was carried out by the joint working group of ISO/TC 199 – IEC/TC 44, which at the time was considering the merging of IEC 62061 and ISO 13849-1.

B 10d Antal cykler tills 10% av komponenterna får ISO 13849-1:2006(en) In order to assist the designer and help facilitate the assessment of achieved PL, this document employs a methodology based on the categorization of structures according to specific design criteria and specified behaviours under fault conditions. Performance levels for ISO 13849-1 are defined in terms of probability of dangerous failure per hour. Five performance levels are set out, from the lowest PL a to the highest PL e with defined ranges of probability of a dangerous failure per hour as per following table: Functional safety EN ISO 13849-1 (PL) Safety Instrumented System SIS (safety loop) Machinery directive 2006/42/EG has been valid since the 1st January 2010. It was signed on 17 May 2006 and published in the Official Journal of the European Union (OJ L 157) on 9 June 2006.

The PL obtained using this table refers to reliability values at mid-position for each of the intervals in Table 3 of ISO 13849-1. We have: PL low = d N low = 1 (< 3) Therefore: PL total = d and average probability of dangerous failure per hour for the entire system will be a number somewhere between ISO 13849-1:2015 3 Diagnostic Coverage (DC and DC avg) in % DC Ratio of Detected Failures to Danger to all Failures to Danger which result in the loss of the Safety Function for a component or sub-system DC avg Rate of failures to danger detected divided by the rate of all failures to danger for ALL COMPONENTS in the SRP/CS 4 Common Cause Failure (CCF) 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). The required PL is determined and assigned as part of the risk assessment in accordance EN ISO 13849-1.

On the other hand, the required performance level In order to assist the designer and facilitate the assessment of achieved PL, 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. • EN ISO 13849-1 employs one of these methods where the following parameters are evaluated: S – Severity of injury F – Frequency and time of exposure to the hazard P – Possibility of avoiding the hazard or limiting the harm. Safety Standard ISO13849-1 SF = safety function PL = performance level PLr = required performance level • PL (Performance Level) is a technology-neutral concept that can be used for electrical, mechanical, pneumatic and hydraulic safety solutions. • SIL (Safety Integrity Level) can, however, only be used for electrical, electronic or programmable safety solutions. Experience EN ISO 13849-1 uses categories from EN 954-1 for defining 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.

This revision has caused major changes in the fundamentals of safety system design. The EN 954-1 standard (categories) is being phased out and replaced by EN ISO 13849-1 (PL, Performance Level) and EN 62061 (SIL, Safety Integrity Level). Although the deadline for using EN 954-1 is set to 31/12/2011, it is beneficial to start applying the new standards as soon as possible as many new standards no longer refer to EN 954-1. ISO 13849-1:2015 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. The performance level (PL) is designated by an alphabetic character, a thru e, with PLe being the highest risk level. EN/ISO 13849-1 assigns a performance level (PL) rating from a to e, with PLe being the highest risk.

Image credit: TUV Once the performance level has been determined, the architecture that facilitates the defined performance level is classified into one of six categories (“B” and 1 thru 5, with B being the least safe and 5 being the most safe). Europastandarden EN ISO 13849-1:2015 gäller som svensk standard. Detta dokument innehåller den officiella engelska versionen av EN ISO 13849-1:2015.

The European Standard EN ISO 13849-1:2015 has the status of a Swedish Standard. • EN ISO 13849-1 employs one of these methods where the following parameters are evaluated: S – Severity of injury F – Frequency and time of exposure to the hazard P – Possibility of avoiding the hazard or limiting the harm.
