For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. 47 rows 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 ISO 13849 is a safety standard which applies to parts of machinery control systems that are assigned to providing safety functions (called safety-related parts of a control system).

The report describes in detail the meaning of each category and also gives an example of … 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. The ISO 13849-1 methodology uses the category of circuit structure/architecture, mean time to dangerous failure (MTTFd), number of cycles with which 10 percent of components have a failure to danger (B10d), diagnostic coverage (DC) and common cause failure (CCF) to determine the PL of … 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.

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.
