DIN EN ISO 13849-2:2013-02

This document specifies the procedures and conditions to be followed for the validation by analysis and testing of the specified safety functions, the category achieved, and the performance level achieved by the safety-related parts of a control system (SRP/CS) designed in accordance with ISO 13849-1. Some validation requirements are general and some are specific to the type of technology used. ISO 13849-2 also specifies the conditions to be followed for the validation by testing of safety-related parts of a control system. Descriptions of the safety functions and the requirements for the categories and performance levels are given in ISO 13849-1 dealing with the general design principles. This second edition replaces the first edition which has been technically revised in order to adapt to the current ISO 13849-1:2006. Furthermore, the new Annex E gives an example for validation of fault behaviour and diagnostic means. This standard deals in particular with aspects of occupational health and safety and product safety and is primarily directed at manufacturers of machines. The committee responsible for this standard is NA 095-01-03 GA "Gemeinschaftsarbeitsausschuss NASG/NAM/DKE: Steuerungen" ("Joint working group NASG/NAM/DKE: Control systems") at DIN.
