Performance level SIL Level a -- b SIL 1 c SIL 1 d SIL 2 e SIL 3 For each individual safety function, the PL of the corresponding SRP/CS must match the “Required Performance Level”. PLr and PL (ISO 13849-1:2006) ISO 13849-1:2006 introduced the idea of a standard for performance levels (PL). This expressed the reliability of a control system's safety-related parts as a quantitative value, including their failure rate and diagnostic coverage. 2019-10-18 EN ISO 13849-1:2015 (Cat. 4, PL e) Safety of machinery.

Integrated enhancements The modular design of VLT® drives means that they can be expanded with options from the factory, or later with simple plug-and-play, to perform complex tasks. As additional options are contained inside the drive, installation is easy and It’s true that the Performance Level (PL) system of EN ISO 13849-1 is quantitative based at the completion of the process. I’ve read that the “fathers” of this standard determined that a quantitative approach was needed to both have a direct comparison to the Safety Integrity Level (SIL) system for hazards and to provide the basis for the validation requirements of EN ISO 13849-2.

• 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

The standard was 2008-06-23 approved and published as SS-EN ISO 13849-1:2008 in English. This document contains a Swedish language version of EN ISO 13849-1:2008. The two versions are valid in parallel. NOTE 1 Designated architectures are defined in Annex B of EN ISO 13849-1 to give a simplified approach for quantification of performance level.

ISO 13849-1:2006 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.

If an electromechanical position switch fulfils the requirements of ISO 13849-1, Annex K, then, due to EN ISO 13849-2, it is about a so called „well-tried component“.

Experience EN ISO 13849-1 uses categories from EN 954-1 for defining 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).

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.

Both IEC 62061 (SIL) and ISO 13849-1 (PL) specify requirements for the design and implementation of safety-related control systems of machinery. The methods developed in each standard are different but, when correctly applied, can achieve a comparable level of risk reduction. COMPARISON OF THE STANDARDS ISO 13849-1, Part 1: General principles for design, provides safety requirements and guidance on the principles of design and integration of safety-related parts of control systems (hardware or software). The international standard ISO 13849-1 allows fault exclusions (see section 7.2): in this case the constructor of a machine has to indicate how these fault exclusions are justified (by description of conditions for the well-tried methods etc.).
