EN ISO13849-1 uses an interactive process for the design of the safety-related parts of control systems, as follows: • A required performance level “PLr” (target value) must be specified for each intended safety function. • The safety function requirements are derived from the necessary risk reduction.

3.1 Required performance level (PLr). När Required performance level (PLr) bestäms, uppskattas eventuella skadornas  PL d/Kat. 3 enligt EN ISO 13849-1 (Performance Level/PL). – SIL 2 enligt EN 61800-5-2 (Safety Integrity Level/SIL).

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.

EN ISO13849-1 uses an interactive process for the design of the safety-related parts of control systems, as follows: • A required performance level “PLr” (target value) must be specified for each intended safety function. • The safety function requirements are derived from the necessary risk reduction.

Piece. EN ISO 13849-1: provides safety requirements and guidance on the principles for There are five performance levels: a, b, c, d, e, with “a” being low risk and “e”  described by the required performance level, PLr for short, which is defined see ISO 13849-1:2015, A.2.3.2.

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.

PLr . The level of each hazardous situation is classified in five stages, from a SIL 2 roughly equivalent to PL d (performance level d). (See IEC 62061 or EN 62061 for more details). Topic: Risk Assessment. Question.

To achieve Performance Level PL d with Category 3 according to ISO 13849-1 under use of only one position switch or only one hinge switch as well-tried component, „fault exclusions“ shall be defined for the „electrical Assigning category and performance level to a safety related system is somewhat complicated in ISO 13849. The following parameters play vital roles: MTTF d per channel; This means "Mean Time to Dangerous Failure" for one channel. Unlike IEC 61508, ISO 13849 is focused rather on channels than on complete safety related systems. The new EN ISO 13849-1 follows a similar process to define a performance level, but the user then has to perform a number of calculations involving diagnostic coverage, mean time to dangerous failure, architecture and common-cause failures to validate that the performance level has been achieved.
