The basic ideas came from IEC 61508 , a seven-part standard originally published in 1998. IEC 61508 brought forward the concept of the Average Probability of Dangerous Failure per Hour, PFHD(1/h). Dang… Designated Architecture Category 3 Typical implementation Contactors with mechanically linked contacts Motor Requirements Safety monitoring relay Contactor monitoring Guard interlock switches •Category B • Well tried safety principles • Single fault does not cause a loss of safety function ISO 13849-1:2015 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. This third edition cancels and replaces the second edition (ISO 13849-1:2006), which has been technically revised. It also incorporates Technical Corrigendum ISO 13849-1:2006/Cor 1:2009 .

A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions. 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
