The EN ISO 13849 series of standards describes simple methods for evaluating safety-related control systems. The PLC disc supports you in estimating the probability of dangerous failure as described in the standard. How is the disc used? To determine the probability of dangerous failure (PFH D) and the associated Performance Level Each architecture is associated with a formula to determine the probability of dangerous failure per hour (PFH d) of the subsystem.

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. possible to accomplish Performance Level PL d with Category 3 according to ISO 13849-1. Application and fastening shall always be carried out considering the manufacturer instructions under the declared specifications and they must not change in the period of operation. This part of ISO 13849 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.

For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. The Performance Level is divided into five categories designated a to e, where a represents the lowest reliability, and e the highest reliability. In other words: the worse the risk, the higher the necessary PL category. SIL. At most companies, SIL is generally seen as solely for the process industry, but this is far from the truth.

To understand ISO 13849 – 1, it helps to know a little about where the standard originated. ISO 13849 – 1 is a simplified method for determining the reliability of safety-related controls for machinery. The basic ideas came from IEC 61508 [7], a seven-part standard origin 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. The performance level (PL) is a value used to define the ability of safety-related parts of control systems to perform a safety function under foreseeable conditions. On the other hand, the required performance level (PLr) is used in order to achieve the required risk reduction for each safety function.
ISO 13849-2, Part 2: Validation, specifies the procedures to be followed for validating by analysis or tests, the safety functions of the system, the category achieved and the performance level achieved. In Part 1, ISO 13849, the design of the safety system is based on the risk assessment performed by the manufacturer of the machine.

Apr 3, 2017 Safety Pressure Switch F01 from STW Technic has received certification according to EN 13849-1 through TÜV Süd and can now be used in Dec 7, 2016 IEC 62061 addresses SIL levels and ISO 13849-1 addresses Performance Levels. While there are two different standards, the scope of each Jun 7, 2017 The performance level is a measure of the reliability of a safety to EN ISO 13849-1, thereby reaching PL d, the second highest reliability level.
