ISO 13849-1 (Safety of machinery - Safety-related parts of control systems - General principles for design), an international standard, was revised in 2006. As the background of the revision, semiconductor parts such as transistors and MOS-FETs have been put to use in the safety machinery that composes the safety-related parts of control systems,

ISO 13849-2, Part 2: Validation, specifies the procedures to be followed for validating by analysis or tests, the safety functions of the system, the category achieved and the performance level achieved. In Part 1, ISO 13849, the design of the safety system is based on the risk assessment performed by the manufacturer of the machine. – also published as ISO 13849-1 : 1999 – based on a risk assessment – Will remain valid until: Got 2 years more so now for use until 2011 • P t 2 f EN 954Part 2 of EN 954-1 [V lid ti ][Validation] – is published as EN ISO 13849-2 : 2003 • EN 954-1 has been revised to include aspects of functional safety. It has changed number to EN SF2 Opening of the safety door leads to halting of all drives of Robots 2, 3 and 4 Figure 3 shows the structure and calculation of the PFHs for these two safety functions.
