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 also gives an example of a category 2 safety function. The EN/ISO 13849-1 machine safety standard uses a qualitative risk graph, or flow chart, to assign a performance level (PL), based on three criteria: severity of injury frequency and/or exposure time to the hazard Figure 3: Safety calculation and design for the emergency stop function according to EN ISO 13849-1 (can also be made according to EN/IEC 62061).

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

Block diagram 3. Provide information about how the machine can be used safely. (For example, in manuals and on signs.) If risk reduction is performed using safety devices, the control system that monitors these needs to be designed as specified in EN ISO 13849-1.
