What is ISO 13849-1:2015 Or. page 3 • 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 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.

Two 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.

The standard defines 5 possible performance levels for a control system, from PL "a" to PL "e" (see Figure 2). Before designing a SF/CS, it is essential to determine the required performance level (PL r) for the safety function. BS EN ISO 13849-1:2015 Safety of machinery. Safety-related parts of control systems.
