It does not give specific requirements for the design of products which are parts of SRP/CS. Nevertheless, the principles given, such as categories or performance
EN ISO 13849-1 uses categories from EN 954-1 for defining the system structure, and therefore the step to the new calculations is not so great if you have previous experience of the categories. EN 62061 defines the structures slightly differently. Customer requirements If the customer comes from an industry that is accustomed

“Stop Category” is a classification of how robot motion is stopped in a safe way. There are three different (See ISO 13849-1 for more details). What is ”PLd” or

ISO 13849 offers 5 so called categories (Cat) and 5 performance levels (PL). Cat B and PL a reflect the lowest, and Cat 4 and PL e the highest safety level.
This standard BS EN ISO 13849-1:2015 Safety of machinery. Safety-related parts of control systems is classified in these ICS categories: 29.020 Electrical engineering in general; 13.110 Safety of machinery ISO 13849-1 is a revised version of EN 954-1. The complex mathematical formulas of the system reliability theory were replaced with pre-calculated tables. Some concepts of EN 954 were retained, i.e. categories, redundancy, monitoring.
Risksituationen bedöms efter en skala med fem steg, så kallade Performance Levels (PL), från PL ”a” (låg) till ”e” (hög). Den nödvändiga PL fastställs inom ramen för riskbedömningen enligt EN ISO 12100 och EN ISO 13849-1. View the "EN ISO 13849-1:2015" standard description, purpose.

The EN 954-1 standard (categories) is being phased out and replaced by EN ISO 13849-1 (PL, Performance Level) and EN 62061 (SIL, Safety Integrity Level). Although the deadline for using EN 954-1 is set to 31/12/2011, it is beneficial to start applying the new standards as soon as possible as many new standards no longer refer to EN 954-1.

Nevertheless, the principles given, such as categories In EN ISO 13849-1, PL is achieved by a combination of Category, MTTFd (mean time to dangerous failure) and diagnostic coverage (DC). According to figure 5 in Calculation of MTTFD values according to ISO 13849-1:2015 If the product is employed for safety-related structures with higher categories (2 to 4) according to .
