EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions. 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). These are designated EN ISO 13849-1 and EN 62061 respectively. EN 62061 is applicable only to electrical control systems.

Complex non-electrical safety-related control systems should be designed to EN ISO 13849-1. In addition, pay attention to the Type C standards that relate to specific categories of machinery; surprisingly, people are often not aware that these standards exist. 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 In Categories 1, 2, 3 and 4, safety principles which are well-tried must also be applied. Information on these aspects can be found in EN ISO 13849-2. Quantitative requirements the observance of which is checked by SISTEMA also apply to the Categories.

EN ISO 13849-1 is the most important standard for regulating the basic principles and performance required of a safety control system for machines and devices. This standard was greatly revised in November 2006.
