possibility of avoiding the hazard or limiting the harm. As the successor to EN 954-1, EN ISO 13849-1 is the main safety standard for the design of safety-related control systems for machinery. Performance Level In contrast to the previous standard EN 954-1, which took a deterministic (reproducible) approach, EN ISO 13849-1 is based on a probabilistic approach to assessing safety-related control systems. – 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.
