This risk assessment identifies the safety functions required to mitigate risk and the performance level these functions need to meet to adequately mitigate the
This chart shows the relationship between Category, Diagnostic Coverage, and Mean Time to Dangerous Failure for PL levels under EN/ISO 13849-1. Note also the correlation with PFH D rates. Image credit: ABB. Note that the Performance Levels (PL) under ISO 13849-1 correspond to certain PFH D ranges — so can be cross-referenced to SIL levels
A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions. Categories were used also in the earlier machinery safety standard EN 954-1:1996. The report describes in detail the meaning of each category and The performance level (PL) is a value used to define the ability of safety-related parts of 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 2013-10-02 designated EN ISO 13849-1 and EN 62061 respectively. EN 62061 is applicable only to electrical control systems. Performance Level (PL) ISO 13849-1 defines how to determine the required Performance Level (PL) and how to verify the achieved PL within a system. 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.
User information to ISO 13849-1. The result of the procedure is a “required performance level”. (PLr). Applicable standards. • ISO 13849-1 uses a risk graph to determine the required sa to take you through the individual steps until the performance level is achieved. PL d.

Note that performance level (PL) ratings under EN/ISO 13849-1 are also correlated with probability of dangerous failures per hour (PFH d) values, so direct comparisons can be made between EN/ISO 13849-1 performance levels and EN 62061 safety integrity levels. Performance Level d (PL-d) Applicable for test systems in which the test specimen area is accessed more than once every 15 minutes. Performance Level d (PL-d) is the standard option on MTS Landmark Test Systems that are using hydraulic pressure of 57-114 lpm (15-30 gpm). This solution requires a load frame with test area enclosure*, a FlexTest controller and a load frame station supervisor.

ISO 13849-1 Safety of Machinery — Safety-related Parts of Control Systems PL , the achieved performance level of a safety control system after risk reduction has been implemented, must be equal to or greater Medium, b, ---, b, c, c certified for Performance Level "d" (PLd) according to DIN EN ISO 13849. The linear position transducers PLd comply with DIN EN 13849-1 and also with the EN ISO 13849.
which guarantees a high level of safety (SIL 2 according to standard IEC 61508) comparable with performance level "d" (PL d) according to ISO/EN 13849-1/-2

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.
